Å-------------------------------------Beam the width of the locator, at the Front edge.-------------------------------------Æ
Extremely high frequency signals are
transmitted and received in line with
the front edge of the instrument. This
return signal is processed on board
and is reported to the flashing, then
becoming steady, Red LEDs.
When both Red LEDs “LOCK” onto a
target at the same time, a RED Laser
Pointer automatically spots the target
on the surface, IN A DIRECT LINE to
the target at the angle at which you
have detected the target (object).
NOTE: If one Red LED locks onto a
target and the other does not, but you
feel the target should be there, try
twisting your wrist around the axis of
the LED which is locked onto the
target/object. This is done in an
effort to “Line up” the front edge of
the unit (thus the other LED) with the
target… when the second Red LED
locks on, you have then locked onto
a target or object and direction.

This is NOT Radar
The Alignment of Signal to Target
Provides the “lay” or “direction” of the target:
Target Line
Horizontal plane with Laser in Front
Center.
The Target line or edge of an object
must align parallel with the Horizontal
Plane of the locator, for the locator to
“lock onto” the target edge. This
provides “direction” of the target edge.
If one Red LED is solid the locator is
not ‘parallel” with the target, OR, there
may be a false target.
Rotate the locator with wrist action
around the axis of the Red LED that is
solid, to attempt to “line the locator up”
with the target.
Hard to Show in a picture:
When the Red LEDs indicate
that a target has been “locked”
onto, and the automatic RED
“Position” Laser activates, it will
appear in a “Direct Line” looking
right across the top of the
locator like aiming a pistol. It is
also the direct line angle to the
target.

Please Notice: The “hand” is
not “high up” on the handle,
nor any other object near the
“head” of the locator/detector.
Technology Overview
This is not “GPR” (Ground Penetrating Radar), although mu ltiple signals are sent/received and processed. The technology is
proprietary, and patents are pending. “AML” is also Trademarked. So we are not going to talk about the technology, itself. This
is a single handheld unit that weights about 2.5 pounds, and is simple and easy to use… it just takes patience and common
sense. The locator cannot “tell you” what the target is; that’s up to you. It simply tells you a target has been located.
The great thing is this locator finds just about everything. That means it finds about everything you can find with current
technology magnetic, metal detector, radio frequency, and GPR locators; AND about everything else that they CAN’T find. You
just have to know, or figure out, what you are “on”. You can test the unit with the same type target you will be searching for
underground if you find the target in an open or partially filled trench, but completely buried is best. With the knowledge and
understanding that one must go slowly and use common sense; one should understand that this is a great tool. The locator
loves “edges” of objects.. That means that you can transition from known pipe locations of metallic pipe/cable, or have properly
installed tracer wire; right onto those sections that turn into non-metallic pipe, or the tracer wire is not installed properly, or has
corroded over time. Let’s explore further:
If you use the “AML” to find those things that you know are “…somewhere over here. …run through somewhere along there… I
know it’s down here somewhere, but I just can’t find it with my other locators.” You can see how valuable it is. You may not
have been able to find these items at all before now, unless you hit one. What a difference that makes! And, that’s just pipes &
cables… what about all the other markets… use your imagination… the possibilities are nearly endless. However, the
responsibility of locating/detecting, safety, and confirming the target, as always, still lies with the Operator. Like any “tool” the
more you use it, the better you get. As you can imagine, however, a trench with lots items in it close together will be near
impossible to pick out (follow) one single target.
There have been many cases during testing and demos, where we found the target in a matter of seconds. There is NO setup,
NO plugging in cables, NO installing ground stakes, NO trying to run a “snake”, “fiche”, or “sonde” up a non-metallic pipe to then
hook onto, and still not work part of the time. NO “squiggly” lines to try to interpret. NO need to be an engineer to operate it.
Pull it out, turn it on, and start detecting. One word of caution: There is no way to make this unit impervious to physical abuse;
you must protect the unit against physical shock. Working in rain may be a problem; if it’s uncomfortable for you, it will be so for
the unit. Like a horse, “don’t put it away wet”; let it dry off before putting it back in the case. But, DO NOT THROW this un
it
anywhere; not even in the case. It is a scientific instrument, treat it as such… take care of it, and it will take care of you.

Searching for Pipes & Cables – Scan & Step
• (We’ve located pipes & cable in a matter of seconds using this
method.) Walk up fairly close to the area where the pipes or
cables are thought to be, and...
• Turn on the “AML”. Stand still and point it across to the other side
of the area… Scan a 6’ swath or less, at a time., even 2 to 4’ is
better. (Pretend you are “slicing the earth” in front of you,
attempting to “slice” the pipe, cable, or object in two.)
• Bring the “AML” slowly down through the area from that point of
beginning, to near your feet… being careful not to get too close to
your feet, or you’ll “locate” them, as well.
• NOTE PHOTO AT RIGHT: When the two “RED indicator LED’s”
are lit up at the same time, it is a “hit”; the locator has detected an
object. Continue through the “swath” and mark or remember each
“hit”, then:
• You MUST “confirm” that you ARE on your DESIRED valid target,
take a couple steps to your right or left, or both, and repeat the
scan; and mark the “hits”. Do the hits “line up”? Is this
reasonable? If you need to pinpoint exactly where the target is,
then move to your mark or past it, and hold the AML vertically
(pointed directly at the ground)… move it slowly to find the “hit”.
When detecting, move the unit, not your feet.
• NOTE PHOTO AT RIGHT: The orange spots are marks where we
had “hits”… (There were two more marks to the left that are out of
this picture.) In this “trial” we detected two non-metallic natural
gas lines, 18” apart, parallel to and 3 feet from a third gas line
marked by the required “utility marking service”… these adjacent
two lines could not have been detected with “RF” locators.
• If the pipe or cable turns, make your scans closer together; and/or
scan at varying degrees to the line… 20, 45, 90, etc. It is
“possible” to “scan” down the line but must be done slowly &
carefully. It’s just a lot easier to “scan & step” sideways.
RED Laser Pointer comes on, and points to a spot on the ground, when a
target has been detected.

About Pipes & Cables
• The “AML” MAY detect the edge–middle–edge of a shallow pipe, or a large pipe, as you “slice” through the
cross-section. If it is a non-metallic pipe with a tracer wire, you may detect the edge-middle-edge-wire or
wire-edge-middle-edge… depending on which side of the pipe the wire is on, in the trench; unless the wire is
in direct line with the edge or middle of the pipe. …as show below:
Pipe
w/Cable
End View
<Cable
“hit” “hit” “hit” “hit”
If Searching Vertically as in Pinpointing:
If Searching at an angle:

While we’ve found the “scan & step” method to be the quickest in most cases; if the pipe is large enough, one may be able to trace
slowly along the pipe similar to the method of using an “RF” locator, if one moves slowly, and keeps the unit steadily “on” the pipe
while holding the unit in the vertical position only… do NOT swing back and forth like an “RF” locator. In such a case, one would
detect only the “center hit”, unless the pipe is very large. One reason we don’t use the walk-in-line method is it is hard not to detect
your feet or shoes when walking and holding the unit vertical.
You MAY be able to “test” the AML on pipes & cables lying on top of the ground or in an open trench so that you can see exactly
how it locates… Keep in mind that it “loves” edges: that is, the sides and top of a round pipe, again depending on size… thus a
small cable or pipe, or a deep one, would only produce one “hit”, on the rounded side that is directly in line with the unit.
Pipe & Cable cross section on the right
shown “oblong” on purpose. The unit will
detect the “edges” it “sees” in a direct line
from/to the unit. If the pipe at the right
were perfectly round, the hits may be
exactly the same distance from the side
as they were from the top. Notice also
that the cable is in the path of the bottom
edge of the pipe, so only three “hits”
would be seen in the case from the right.
11
NOTE: It may not always be possible to detect the
target at 45-degrees due to distance caused by depth.
Some Other Objects:
-Key Point to Remember from the last slide – The AML “loves edges” –
-That could be the center “edge”, the side edges, or all three-
-The composition of the object does not matter –
Septic Tanks, Boxes, and all types of buried Drums: Imagine the edges of the tank, box, or drum, and align yourself to
point the locator in such a manner as to detect the edges as previously discussed. By walking around the tank and taking
scans (slicing the tank in two), one can define the outline of the tank. Remember also, that “rounded edges” like a round pipe
will be defined as an edge. The flat surface of the side or top may be detected if the locator is pointing directly at the flat
surface. If the tank has one or more “clean-out lids” on the top, the edges of that lid may also be detected. If one is careful,
one may be able to keep the locator on a detected edge and slide carefully along the edge to outline it, until it turns a corner.
The drain-field pipes are also detectable by the “scan & step” method.
Graves/vaults/Skeletons: Coffins & vaults would be detected as described above. A buried body or skeleton would be
detected by “hits” on the individual larger bones, and multiple hits on groups of smaller bones.
Buried Walls & Old Foundations: May be detected by the edges of the wall or foundation by the same “scan & step” method.
Storm Sewers and other concrete pipe, or pipe-like structures: would be detected like any other pipe, just remember the
estimated size of such a pipe, it’s shape, and any joining structures; in order to imagine where “edges” would be formed.
Rebar in Concrete, Hot Water Pipes in Concrete Floors: Rebar can be detected in concrete by the same method as
detecting pipe in the ground. One may also be able to “slide” along a piece of rebar once detected if very careful. To detect a
pipe or cable under a concrete floor with rebar in the concrete, is slow and tedious, may be done, but is very time consuming.
One may identify the rebar and then the pipe that runs at an angle to the rebar, and/or between the rebar at other than a normal
distance between the bars… but is very tedious, and may just be too difficult. If the concrete is reinforced with fiberglass
particles instead of rebar, detecting a pipe or cable in it becomes easy, because the reinforcement would not be detected.
Think about it… since the AML finds just about everything, it will also find things like tree roots and other things that could
have been “thrown” in the ground and covered up at construction sites… thus the need to always “verify” your locate.
12
About Depth & Depth Estimating
“Triangulation”
• This model is not capable of push-button depth – so triangulation may be used on some
targets. (*See next page for additional information on “triangulation”.)
• Use the appropriate method, previously discussed, to find the target while holding the locator
at a 45 degree angle; and note/mark the spot of the laser point on the ground.
• Go to where you think the target would be directly below, based on the angle at the time of
detection; and detect the target with the locator in the vertical position. This is “pinpointing”
directly over the target. (Be careful to avoid detecting one’s own feet.) Mark the spot of the
laser point on the ground.
• The distance between the two marked spots is the estimated depth of the target. *
• Remember, that is the depth from the surface to the “detected edge” of the target. If it is a
shallow or very large pipe, I’d want to do the depth to the center mark (center edge). *
• 10 to 12 feet is the depth that the AML has been repeatedly tested.
Objects have been
found up to 20 feet deep, but they were large and the edges were not precise.
*Regardless, depth by any method, by any locating instrument, should always be considered to be an
“estimate”… BE AWARE that “Triangulation” may NOT be possible, due to the distance necessary to
make the detection at distance from a 45-degree angle. Deeper targets may make it impossible to do
Triangulation because of the greater distance to the target at 45 degrees.

Distance between “spots” is the depth*
NOT Drawn to Scale!
The triangle on the right, if drawn to scale,
would have vertical and horizontal sides
“equal” -- The depth equals the distance
between the two “marked spots”, as long
as the “laser pointer line” is at a 45
degree angle… depending on the
diameter of the target.
Now, notice the triangle at the left does not
completely reach to a “point” at the bottom,
the two sides do not “join” at the bottom.
The vertical side comes off the closest
point: the top of the pipe. The 45 degree
angle comes off the closest point of the
angle in that direction, so the sides do not
meet.
So. If the target were a “wire”, the distance
would be extremely accurate. If the target is
a 48” diameter pipe, the measurement
would be off 2 feet… The top of the pipe
would be 2’ higher than the measured
distance, because the sides of the triangle
come to a point in the center of the pipe.
So: KNOW YOUR TARGET!
(We’re picking the center
detectable “edge” of the
target for this example –
not the outside edges.)
14
*unless the target is not of a small diameter. See the bottom of the corner of the triangle
above as it (hidden) meets at the center of the target… so it will be “shallower” then the
distance between the “spots”, or about ½ the diameter of the target.
