Important Notice

The NaviTrack® II is a diagnostic tool that senses electromagnetic fields emitted by objects underground. It is meant to aide the user in locating these objects by recognizing characteristics of the field lines and displaying them on the screen. As electromagnetic field lines can be distorted and interfered with, it is important to verify the location of underground objects before digging.

Several utilities may be underground in the same area. Be sure to follow local guidelines and one-call service procedures.

Exposing the utility is the only way to verify its existence, location and depth.

Ridge Tool Co., its a liates and suppliers, will not be liable for any injury or any direct, indirect, incidental or consequentialdamagessustainedorincurredbyreasonof the use of the NaviTrack® II.

OperationTime

Using alkaline cells, typical operation time is from about 12 to 24 hours depending on sound volume and how often the backlight is on. Other factors that a ect the operation time will include chemistry of the battery (many of the new high performance batteries, such as the “Duracell® ULTRA” last 10%-20% longer than conventional alkaline cells under high demand applications). Operation at lower temperatures will also reduce battery life.

The NaviTrack® II display can also show random symbols when the battery power is too low to drive the internal logic circuits correctly. This is remedied by simply putting fresh batteries into the unit.

Sonde Locating

The NaviTrack® II can be used to locate the signal of a sonde (transmitter) in a pipe (must be a non-metallic pipe !!), so that its location can be identified above ground. Sondes can be placed at a problem point in the pipe using a camera push rod or cable.They can also be flushed down the pipe.

IMPORTANT! – Signal strength is the key factor in determining the sonde’s location. To ensure an accurate locate, take care to maximize the signal strength prior to marking an area for excavation.

Thefollowingassumesthatthesondeisinahorizontalpipe, the ground is approximately level and the NaviTrack® II is held with the antenna mast vertical.

The field of a sonde is di erent in form than the circular field around a long conductor such as a pipe or cable. It is more like the field around a bar-magnet, with a north pole and a south pole. Because of di erences in the two kinds of fields, the display in Sonde mode shows signal strength in the upper left corner, rather than Proximity signal.

In the sonde’s field, the NaviTrack® II will detect the points at either end where the field lines curve down toward the vertical, and it will mark these points on the map display with a “pole” icon (). The NaviTrack® II will also show a line at 90 degrees to the sonde, centered between the poles, known as the“equator”, much like the equator on a map of the Earth.

Pole	Pole

When locating a sonde set up the locate in the following manner:

•Activate the sonde before putting it in the line.

Select the same frequency on the NaviTrack® II and make sure it is receiving the signal.

Figure 17: Sonde Frequencies On the Main Menu

•After the sonde has been sent into the pipe, go to the suspected sonde location. If the direction of the pipe is unknown, push the sonde a shorter distance into the line (~4-5 m from the access is a good starting point).

Location Methods

There are three major parts to locating a sonde. The first stepistofinddirection.Thesecondpartishominginon(or “localizing”)theareaofthesonde. Thethirdiscompleting the locate by pinpointingits location.

Step 1: Finding the Direction

1.Hold the NaviTrack® II so the antenna mast is pointing outward. Sweep the antenna mast in the suspected direction of the sonde while observing the signal strength and listening to the sound. The signal will be highest when the antenna mast is pointing in the direction of the sonde.

2.Lower NaviTrack® II to its normal operating position (antenna mast vertical) and walk in the direction of the sonde. Approaching the sonde, the signal strength will increase and the audio tone will rise in pitch. Use the signal strength and the sound to maximize the signal.

10

Step 2: Localize the Area

1. Maximize the signal strength. When it appears to be at its highest point, place the NaviTrack® II close to the ground over the high-signal point. Note the Signal Strength and move away from the high point in all directions. Move the NaviTrack® II far enough in all directions to verify that the Signal Strength drops significantly on all sides. Mark the point of highest signal strength with a yellow marker.

2.If while“getting closer”a stable equator appears on the screen it can be followed toward an increasing signal strength to localize the sonde.

Figure 18: Poles and Equator of a Sonde

3.If while“getting closer”a pole appears first, localize the sonde by centering in on the pole icon (the icon may move closer in to the sonde as the receiver approaches it).

Step 3: Pinpoint the Sonde

The poles should appear on either side of the maximum signal point, an equal distance on either side if the sonde is level. If they are not visible on the screen at the point of maximum signal strength, move from the maximum point perpendicular to the dotted line (equator) until one appears. Center the locator over the pole.

The dotted line represents the equator of the sonde. If the sonde is not tilted, the equator will intersect the sonde at maximum signal strength and minimum depth. NOTE: being on the equator does not mean that the locator is over the sonde. Always verify the locate by maximizing signal strength and marking both poles.

1.Mark the first pole location found with a red triangular marker. After centering on the pole, a double-line indicator will appear representing the direction of the sonde

When the locator gets close to a pole, a focusing ring will appear centered on the pole, allowing precision centering.

2.The second pole will be a similar distance from the sondelocationintheoppositedirection.Locateitinthe same manner and mark it with a red triangular marker.

3.Ifthesondeislevel,thethreemarkersshouldbealigned and the red pole markers should be at similar distances from the yellow sonde marker. If they are not, a tilted sonde may be indicated.

Verify. It is important to verify the sonde’s location by crosschecking the receiver’s information.

4. Double-check. Move the NaviTrack® II away from the maximum signal strength, to make sure that the signal drops o on all sides. Make sure to move the unit far enough to see a significant signal drop in each direction.

Figure 19: Sonde Locate: Equator

5.Double-check the two pole locations.

6.Notice that the depth reading at the maximum signal strength location is reasonable and consistent. If it seems far too deep or too shallow, recheck that there is an actual maximum signal strength at that location.

7.Notice that the poles and the point of highest signal strength line up.

IMPORTANT! – Remember that being on the Equator does NOTmeanoneisoverthesonde.Note that seeing two poles aligned on the display is not a substitute for centering over each pole separately and marking their locations as described above.

It is important to realize that a severely tilted sonde can cause the pole locations and the equator to appear out of true because of the angle of the sonde; but the signal strength will still guide to the best location for the sonde.

Figure 22: Tilted Sonde, Poles and Equator

Note the right-hand pole is closer to the equator, due to tilt.

Floating Sondes

Some sondes are designed to be flushed or to drift down a pipe pushed by water flow. Because these sondes swing much more freely than a torpedo-shaped sonde in a pipe, they can be oriented any which way.

This means the equator may be distorted by tilting, and the location of the poles may vary. The only guarantee of having located a floating sonde is maximizing the signal strength and double-checking that the signal falls away on every side of the maximum signal location.

Measuring Depth

The NaviTrack® II measures depth by comparing the strength of the signal at the lower antenna to the upper antenna.

Depthismeasuredcorrectlywhenthemastisheldverticaland the bottom antenna is touching the ground directly above the signal source.

Active LineTracing

In active line tracing, underground lines (lines that can“carry” anelectromagneticsignal(thusplasticpipescannotbelocated this way)) are energized with a line transmitter. This active signalisthentracedusingtheNaviTrack® II.Alinetransmitteris di erentfromasondeinthatitisusedfortracinganenergized line,ratherthanactingasatargetforalocateasasondeis.Line transmitters energize lines by direct connection with clips, by directly inducing a signal using a clamp, or by inducing the signal using inductive coils built in to the transmitter.

1.Energize the line according to the manufacturer’s instructions. Select the transmitter frequency.

Set the frequency used on the NaviTrack® II to the same frequency used on the transmitter. Be sure it has a line trace icon . Push the main menu button to return to the map display.

4.Use the Proximity Number, Signal Strength, and Signal Trace Lines to guide the line trace. These three pieces of information are generated from discrete signal characteristics to help the locator discern the quality of the locate. An undistorted signal emitted from a line is strongest directly over that line. By maximizing the Proximity Signal, and centering the Signal Trace Lines on the screen the confidence in a “good” locate is high. Confirm a locate by testing whether the depth reading is stable and reasonable. One way to test for the consistency of the depth reading by raising the NaviTrack® II a known distance (say, 35 cm exactly) and observing whether the depth indicator increases by the same amount. Small variation is acceptable, but if the depth does not change, or changes drastically, it is an indication of a “distorted” field, or very low current on the line. (As always, the only way to be completely certain of the location of a utility is through visual inspection by exposing the utility.)

Figure 24: High Probability Locate

CAUTION:Careshouldbetakentowatchforsignalinterference that may give inaccurate readings. Depth readings should be taken as estimates and actual depths should be verified by exposing the line before digging.

Using a LineTransmitter

In active Line Tracing, the NaviTrack® II works in conjunction with an active line transmitter unit. There are three ways to connect a line transmitter.

Direct Connection

The best way to connect a transmitter is usually by directly connecting it (metal to metal) to one end of a target utility pipe, trace-wire or cable, and sending the transmitted current directly along the target.

Clamp Connection

Where direct connection is not possible, it is often possible to fix an inductive clamp connector around the target conductor, which energizes it inductively. To e ectively induce a signal using a clamp, the line must be metallic, and must have both ends of the line grounded. (Signal can not be induced onto a line in one direction unless current is able to flow in both directions.)

InductiveTransmission

The transmitter can be used in an inductive mode without a direct connection.This requires making sure the transmitter is directlyoveraknownsegmentofthetargetlineandactivating the transmitter’s “inductive mode” which will illuminate the line at a selected frequency.

NOTE: Refer to the manual provided with the transmitter being used to ensure it is properly connected and grounded, and set to the correct frequency.

NaviTrack® II

Each of these methods has advantages depending on the situation. Direct connection is usually most reliable in that the signal is being applied directly to a known line; but situations exist where induction may be the only option, or may work better.

Passive LineTracing

InpassivemodetheNaviTrack® IIsensesalternatingcurrent,or AC fields generated by wires already carrying current, without a transmitter being attached. Buried power lines typically do not emit any traceable signal unless power is flowing in the wires. For example streetlights that are turned o are hard to trace passively. Due to coupling (either through induction or through capacitance), all metallic lines in an area can be energizedpassively.Becauseofthisitispossibletolocatelines passivelybutitcanbedi culttoidentifywhichlinethelocator is tracing.

WARNING:Inpassivelocatingorwhensignalsareextremely weak, the depth will generally read too DEEP and the actual buried depth may be MUCH shallower.

1.Select a Passive AC Trace Frequency with the passive line trace icon.

Figure 25: 60 Hz Passive Trace Frequency

2.The NaviTrack® II has two passive AC tracing frequency settings. They are 50 Hz, and 60 Hz. They are identified with the power icon.The 50 Hz and 60 Hz respond to a harmonic of commonly used AC frequencies. European installations are typically 50 Hz.

When passive tracing, it is important to remember that T’s, curves, other conductors in the vicinity, and nearby masses of metal can add distortion to the field requiring closer scrutiny of the data to determine the path of the target.

In general, passive tracing is the least e ective option.

NaviTrack® II

OperatingTips for LineTracing

•The NaviTrack® II quickly identifies distorted fields. If the lines are not centered on the map, and Proximity Signal or signal strength is maximized, distortion is creating a complex rather than circular field. To improve the tracing circuit:

a)Try changing the frequency used to a lower one.

b)Move the ground stake position away from the line being traced.

c)Make sure that the line is not commonly bonded to another utility. Undo common bonds only if safe to do so.

d)Move the transmitter to a di erent point on the line and try doing the trace in the opposite direct (B to A instead of A to B).

•If the lines will not center or if they move across the screen erratically, then the NaviTrack® II may not be receiving a clear signal. The depth and the Proximity Signal may also scroll up and down under these circumstances.

a)Check the transmitter to be sure that it is operating and well grounded.

b)Test the circuit by pointing the lower antenna at either transmitter lead.

c)Check that the NaviTrack® II and transmitter are operating on the same frequency.

d)Try di erent frequencies, starting with the lowest, until the line can be picked up dependably.

e)Re-locate the ground connection for a better circuit. Ensure there is enough contact (ground stake is su ciently deep) especially in dryer soils.

•While tracing, the signal should maximize, and the depth minimize, at the same place where the lines center on the display. If this is not the case, the utility may be changing direction or other coupled signals may be present.

•Higher frequencies bleed over more but may be needed to jump breaks in tracer wires or go over insulating couplers. If the line is ungrounded at the far end, higher frequencies may be the only means to make the line visible (see Figure 37).

•When using the transmitter inductively, be sure to begin the locate about 10 m feet away to avoid“direct coupling”,

also known as air coupling or “air lock”. This occurs when the NaviTrack® II picks up the signal from the transmitter directly through the air and not from the line to be traced. To test for air coupling, point the NaviTrack® II directly at the transmitter; if signal strength increases, then the transmitter is too close to the receiver to trace accurately.

•While tracing, the mapping display operates best under the following conditions:

1.The Line is level

2.The NaviTrack® II Locator is above the target utility level

3.The NaviTrack® II antenna mast is held approximately vertical

If these conditions are not met, pay close attention to maximizing Proximity Signal and signal strength.

In general, if the NaviTrack® II is used in a zone over the target line within a sweep area of about two“depths”of the line, the map will be useful and accurate. Be aware of this when using the map if the target or line is very shallow. The useful search area for the map can be small if the line is extremely shallow.

Measuring Depth

The NaviTrack® II measures depth by comparing the strength of the signal at the lower antenna to the upper antenna.

Depth is measured correctly in an undistorted field when the bottom antenna is touching the ground directly above the signal source.

1.To measure depth, place the locator on the ground, directly above the sonde or the line.

2.Depth will be shown in the lower left hand corner. A depth reading can be forced by pressing the Select key.

Clipping

Occasionallythesignalstrengthwillbestrongenoughthatthe receiverwillbeunabletoprocessthewholesignal,acondition known as “clipping”. When this occurs a warning symbol will appear on the screen. It means that the signal is particularly strong. If clipping persists, it can be remedied by reducing the strength of the current from the transmitter.

NOTE: In Line Trace mode, pressing the Select key will force a depth reading and will force the angle indicator to change to current. If sound is turned on, it will also re-center the audio tone.

NaviTrack® II

Appendix: A BetterWay Of Locating

TheNaviTrack® IIisaprofessionallocatorusedfortracingburied lines, pipes, cables and locating sondes. The NaviTrack® II uses Omnidirectional antennas and advanced processing to make locating sondes and tracing buried utility lines fast, accurate and easy. It has a number of features which advance the art of locating significantly.

The NaviTrack® II gives the operator a picture of the situation around as the receiver moves along the target area and makes it easier to understand where a target line’s electromagnetic field is. It shows what the situation is with the line or sonde being located. With complete information, an operator can understand how things stand underground and resolve complex situations, avoid inaccurate mark-ups, and find the right line or cable more rapidly.

WhatThe NaviTrack® II Does

The NaviTrack® II is used above ground to sense and trace electromagnetic fields emitted from underground or hidden lines (electrical conductors like metal wires and pipes) or sondes (actively transmitting beacons).

When the fields are undistorted, the information from the sensed fields gives an accurate picture of the buried object. When the situation is made complex by interference from more than one line or other factors, the NaviTrack® II provides a display of information that show multiple measurements of the detected field. This data can make it easier to understand where the problem is, by providing clues as to whether a locate is good or bad, questionable or reliable. Instead of just laying paint in the wrong place, a locator can see clearly when a di cult locate needs re-evaluation.

The NaviTrack® II provides more of the critical information a locator needs to understand the situation of the utility being located.

What It Does Not Do

The NaviTrack® II locates by sensing electromagnetic fields surrounding conductive objects; it does not sense the underground objects directly. It provides more information about the shape orientation, and direction of fields than other locators but it does not magically interpret that information or provide true X-RayVision.

A distorted, complex field in a noisy environment requires intelligenthumanthoughttoanalyzecorrectly.TheNaviTrack® II cannot change the results of a di cult locate, even though it shows all the information about those results. Using what the NaviTrack® II shows, a good operator can improve locating results by “making the circuit better”, changing frequency, ground or changing the transmitter’s location on the target line. This gives the locator a better chance of getting it right the first time.

Advantages of the

Omnidirectional Antenna

Unlikethesinglecoilsusedinmanysimplelocatordevices,the Omnidirectionalantennadetectsfieldsonthreeseparateaxes, and can combine these signals into a“picture”of the apparent strength, orientation and direction of a field. Omnidirectional antennas o er definite advantages:

The Mapping Display

ThemappingdisplayenabledbytheOmnidirectionalantennas provides a graphic view of a signal’s characteristics and a bird’s eye view of the signal underground. It is used as a guide for tracing underground lines and can be used to better pinpoint sondes. It can also be used to provide more information for complex locates.

The use of lines (representing the signals sensed by upper and lower antennas) gives the locator a graphic way to see where he is, and where the target utility or sonde is. At the same time the display provides all the information needed to understand what is happening with the field being located

–itssignalstrength,continuousdistance,angle,andproximity to the target.The information available at one moment on the NaviTrack® II would take multiple sample readings with some conventional locators. A distorted or compound field will be easiertointerpretwhenalltheinformationisinasingledisplay as it is with the NaviTrack® II.

Orientation to the Signal

Because of the multiple signals being processed by each Omnidirectional antenna, the target’s signal always gets stronger as the receiver gets closer to the target. How the unit is held does not a ect signal strength. The user can approach from any direction and does not need to know the lie of the pipe or wire.

Locating Sondes

Used with a sonde, the NaviTrack® II eliminates Nulls and ”Ghost Peaks”. A conventional locator signal often sees a signal increase followed by a null (better described as no signal registering on the antenna) and then a peak.This can confuse the operator especially if they interpret a smaller peak as the target.

False Peaks

by a conventional locator

The main peak is in the center, and two false peaks

are outside the two nulls.

The NaviTrack® II uses just one peak to draw the user to the target. Finding a sonde using signal strength is a very direct process.

The only way to go is “up” toward the maximum

signal.

NaviTrack® II

Proximity Signal

TheNaviTrack® II’sProximitySignalisanewpieceofinformation

– a tool to help center the locator on the target line. It tells the operator how close the instrument is to the target. Using the Proximity Signal in a locate gives a more defined peak than using simple signal strength.

The proximity signal is based on comparing the information being sensed by two Omnidirectional antennas in the upper and lower node casings of the NaviTrack® II. The NaviTrack® II provides an instant, integrated picture of field conditions at any moment and location along the line trace.

“Informational”Locating

Because of NaviTrack® II’s advanced processing and display, the information provided by the NaviTrack® II makes it clear when a good locate is certain, and when a locate is suspect.

A good locator can understand the underground picture with much less e ort by using the combined information provided by:

•Proximity Signal/Signal Strength

•SignalTrace Lines from each antenna

•Continuous Depth indications

These indicators show what the antennas are “sensing” as theymovethroughthefield. Thissignalswhenafieldisbeing pulled or pushed out of shape by interference from other lines or objects nearby, because either indicator will disagree with other indicators when significant distortion is present. Knowing distortion is present allows the operator the option of taking action to reduce it or at least account for it. (For example, depth reading in distorted fields becomes suspect.)

The other side of having more information is verification that a locate is good. If all of the indicators are in agreement and reasonable, then the degree of confidence in a locate can be much higher.

GettingThe Most Out

OfThe NaviTrack® II

The basic features of the NaviTrack® II make it quick to learn. But the instrument also has advanced features that will make locating in tricky conditions much easier if the operator understands what they are showing him.

More on Informational Locating

The normal shape of a field around a long conductor such as a pipeorcableiscircular.Whenoverthecenterofacircularfield, expect the following indicators:

•Maximum signal strength

•Maximum Proximity Signal (LineTrace Mode)

•Centered trace lines

•Reasonable and consistent depth reading

•Sound pitch and volume will increase until they maximize over the line.

The experienced operator learns to“see”the ground situation by knowing how the di erent pieces of information provided by the NaviTrack® II relate to each other. While a simple straightforwardlocateofacircularfieldisfastandeasy,tracing alinewhichisnearotherlargeconductorssuchaspowerlines, phone lines, gas mains or even buried scrap metal can lead to questions which can only be correctly answered by taking all the available information into account.

By comparing signal strength, angle, proximity signal, the Signaltracelines,anddepthanoperatorcanseewhichwaythe field is being distorted. Comparing the field information with an educated view of the ground, noticing where transformers, meters, junction boxes, manholes and other indicators are located can help in understanding what is causing field distortion. It is important to remember, especially in complex situations,thattheonlyguaranteeofthelocationofaparticular line or pipe is actual inspection, such as by potholing.

Notes on Accuracy

Depth, Proximity and Signal Strength measurements rely on a strong signal being received by the NaviTrack® II. Remember that the NaviTrack® II is used above ground to sense electromagnetic fields emitted from underground lines (electrical conductors like metal wires and pipes) or sondes (actively transmitting beacons). When the fields are simple and undistorted, then the information from sensed fields is representative of the buried object.

If those fields are distorted and there are multiple interacting fields, it will cause the NaviTrack® II to locate inaccurately. Locatingisnotanexactscience.Itdoesrequiretheoperatorto usejudgmentandlookforalltheinformationavailablebeyond what the instrument readings may be. The NaviTrack® II will give the user more information but it is up to the operator to interpret that information correctly. No locator manufacturer will claim that an operator should follow the information from their instrument exclusively. A wise operator treats the information he gets as a partial solution to the problem of locatingandcombinesitwithaknowledgeoftheenvironment, utilities practices, visual observation and familiarity with the instrument to arrive at an informed conclusion.

Locating accuracy should not be assumed under certain conditions:

•When other lines or utilities are present. “Bleed over” causes distorted fields and will illuminate lines other than the target line. Use lower frequencies when possible and eliminate all connections between the two lines.

Figure 37: Bleed-over

•When T’s, turns or splits are present in the line. When followingaclearsignalthatsuddenlybecomesambiguous, tryseekinginacircleofabout5-6maroundthelastknown point to see whether the signal picks up again. This may reveal a branch, joint or some other change in the line. Be alertto“splitopportunities”orsuddenchangesofdirection in the utility being traced.

•When signal strength is low. A strong signal is necessary for accurate locating. A weak signal can be improved by changing the grounding of the circuit, frequency or transmitter connection. The wise locator also knows that insulation will provide a better signal. Worn or damaged insulation, bare-concentric cables, and iron pipes exposed togroundwillcompromisesignalstrengththroughleakage to ground.

•Far-endgroundingwillchangesignalstrengthsignificantly. Where far-end grounding cannot be established a higher frequencywillprovideastrongersignal.Improvingground conditions for the locating circuit is a primary remedy to a poor signal.

•When soil conditions vary. Extremes in moisture, either too dry or overly saturated, may a ect measurements. For example, ground that is saturated with salty water will shield the signal severely and be very di cult to locate in, especiallyathighfrequencies.Butaddingwatertoverydry soilaroundagroundstakecanmakeamajorimprovement in signal.

•In the presence of large metal objects. Simply walking past a parked car during a trace, for example, can cause an unexpected increase in signal strength, which will revert to normal when past the distorting object. This e ect is stronger at high frequencies, which “couple” more readily onto other objects.

A receiver cannot change the underlying conditions of a di cult locate, but changing frequency, ground conditions, transmitterlocationorisolatingthetargetlinefromacommon ground can change the results, by making a better ground connection, avoiding signal splits, or reducing distortion. Other receivers will indicate that they may be over a line, but they have less ability to tell him the qualityof the locate.

The NaviTrack® II provides more information. If all of the indicators are aligned and in agreement, mark-outs can be made with more confidence. If the field is distorted, it shows immediately. This allows the operator to do something to isolate the target line, change the grounding, connection point, move the transmitter or change the frequency to get better reception with less distortion. For extra certainty, take steps to inspect the situation such as by requesting potholing.
