Introduction

Thank you for purchasing the MarCum VX-1i multicolor sonar unit. The VX- 1i
incorporates all of the sonar technology from the VX-1p, but now with the added
view-ability that the flat face design provides. Still featuring 1000 watts of
peak-to-peak power, patented signal interference rejection, auto zoom, and
target separation down to 2.15 inches. Our goal is to set the industry
standard for performance while maintaining the highest level of reliability.
Please read this manual carefully before using your VX-1i system. Only by
reading this manual can you realize the maximum benefit from your purchase
— enjoy

your

new VX-1i sonar system!

General Description

The VX-1i multi-color sonar unit utilizes three different colors within its display
to differentiate between densities of objects: RED, ORANGE, and GREEN.
The use of different colors in defining return signals is meant to be informative
in indicating the size of fish, type of bottom or location of weeds. The
interpretation of these signals improves with experience and use in the field.

The VX-1i offers multi-level Interference Rejection (IR) from nearby competing
units. This is most prevalent in ice-fishing applications where anglers utilizing
sonar are often grouped together within small areas.

The VX-1i can utilize any one of three different twenty-degree (cone angle)
transducers. The puck-style transducer is often used for mounting on the
bottom of trolling motors or for in-hull applications. The high-speed trans­ducer is intended for outside the hull mounting on the transom of a boat
and is designed for picking up depth or return signals at higher speeds.
The ice transducer is a weighted, self-aligning transducer used for ice-fishing
applications.

Your Marcum is water and weather resistant and is designed to be used in the
outdoors, but in extreme weather conditions, care should be taken to shield
the monitor from driving rain and boat spray. At no time should the monitor
be in direct contact with large amounts of water. Should your VX1-i become
wet, it is unlikely that any harm will come to it, but make sure to get the entire
system completely dried out as soon as possible.

BATTERY CHARGING

Your Marcum system comes with a 3-stage battery charger. This s tyle of charger
has proven to be the most effective and easiest t o use of all char ging systems
available. Because this is a 3-stage charger, there is no dan ger of overcharging your
battery. When properly cared for, a sealed lead acid battery w ill last for at least a
couple of years. Batteries are made to be used, and they need to be used to make
the most of th em. The most important th ing you can do is to promptly recharge your
battery after each use. Not charging your batt ery immediately after use is the
number one thi ng that leads to battery failure.

For safety reasons, it is recommended that you place your system on a flat, hard
surface like cement or tile when charging it, away from any flam mable mater ials. Be
sure to disconnect the charger from t he wall when not in use, and avoid leaving your

battery hook ed up to the c harger for ext ended periods of time.

When you get home from a tri p, put your battery on charge right away and leave it
there overnight, or for around 8-12 h ours. Likewise, on the night before an ice fishing
trip, put it on the charger again, just to make sure. Again, there is no danger of
overcharging your battery. We often talk to people who hesitate to charge their
battery after each use for fear that the battery w ill develop a “memory” and this will
lead to a shortened run time—THIS IS FALSE!!! ALWAYS CHARGE YOUR
BATTERY AFTER EVERY USE!!! Be sure to use the charger that came with your
system, or a sim ilar one that is between .5 amp and 1 amp. Using a larger charger,
like you would use on a car, truck, RV , or boat is likely to cause damage to the
battery. There is really no danger of overcharging your battery with a low amp
charger, and m ost chargers automati c ally go into “maintenance mode” once a full
charge has been achieve d.

CHARGE YOUR BATTERY:

TO

Your batter y has a wiring harness attached to it that has “piggyback” terminals on it,
enabling you to keep the power cord from the unit attached to the battery at al l times,
as well as having the wiring harness with receptacle for your charger attached at all
times. To charge, simply c ouple the end of the charger with the end of the wir ing
harness. I t is normal f or a green light to appear on the charger at this tim e if the
charger is plugged into t he battery only. It is also normal for the light on the charger
to be green if it is just plugged into the wall. When it is plugged into the wall and
battery, you will see a red LED light appear on the charger. If the light is red, the
battery is b eing charge d. When your battery is fully charged, this red light should
change to gre en. If it is time to go fishing and the l ight has not turned green, go fish
and try to allow a longer charging period next time.

Batteries are an expendable item, and must be repl aced perio dically. The batteries
that we use are the “Seale d Lead Acid” variety, they are 12 volts, and range from 7
to 9 amps. The more amps the battery has, the longer it will run on a full charge.
Your Marcum can be powered off of any battery that is 12 volts, even a large
automotive or deep cycl e battery.

you are having difficulty with the charging process, please s ee the Charger

If you need to remove the battery, slide the power cord leads from the battery.
Remove the strap that is holding the battery in place and lift the battery out. To
replace the battery, place a new battery of similar specifications into the battery
compartment and secure it with the Velcro strap and re-connect the positive and
negative terminals.

Ice System Set-Up

Your VX-1i comes virtually ready to fish. All you need to do is hook up the positive
lead from the VX-1i power cord to the battery. Your VX-1i is delivered with a
charged battery, so you can take it fishing right away. Inside the VX-1i deluxe
softcase is an electronics shuttle that has recessed compartments for the battery
and the dual beam transducer. Take the transducer out of the recessed holder and

- 3 -

rotate the adjustable ice arm out from inside the shuttle. The adjustable ice arm
allows for maximum flexibility in positioning the VX-1i around the ice hole.

SETTING THE TRANSDUCER FOR ICE FISHI NG :

When used in conjunction with the retractable pivoting transducer arm and rubber
stopper, the VX-1i ’s transducer will automatically level itself in your ice hole. To begin
operation, take the transducer out of the recessed holder, and rotate the adjustable
ice arm out from inside the shuttle. Extend the transducer arm, (the cable should
already be threaded through it with stopper in place) and deploy the transducer into
the water. We recommend setting your stopper to have the transducer down the least
amount possible. The Marcum VX-1i puts out enough power that in most cases it is
not necessary to have your transducer down more than a few inches below the water
line to get a good reading. When the ice thickness is over two feet, it may be
necessary to have your transducer set somewhat farther down. Remember--the less
transducer cable you have out, the easier it is to pull it out of the water when bringing
in a fish, or to move to a new location. Under no circumstances should you ever have
the ducer below the ice—this can lead to the ducer becoming damaged.
It is also important that you keep t he cable near the center of t he ice hol e. We
frequently hear from angler s who allowed their ca ble to freeze into the side of the ice
hole. If this should happen to you, ma ke sure the unit is turned off before attempting
to chisel it out. If you accidentally cut the ducer cable, do not try to use that ducer
again.

MOVING THE DUCER TO A NEW LOCATION

Being mobile is one of the keys to being successful on the ice. Whenever you move
from one spot to another, it i s tempt ing to leave your transducer h anging on the
transducer arm. This is l ikely to lead to failure of t he transducer arm, and can cause
damage to the transducer itself. Always stow the transducer inside the pack when
you are moving. Keeping the amount of transducer cord you have out at a minimum
will make transporting your VX-1i easier. Similarly, you may need to quickly remove
your transducer from the hole when about to land a fish. We have actually seen
anglers in a panic actually grab the shuttle itself and toss the entire unit to the side.
This is no way to treat any piece of electronics; a much better approach is to simply
lift the transducer out of your way by the cord, and the shuttle itself can be gently
pushed aside. Whenever you are moving via sled or vehicle, always fold up your
transducer arm, stow the transducer inside, and close the protective soft pack.

READ ING TH ROUGH ICE –

The VX-1i will provide accurate information reading through ice providing the ice is
reasonably clear. Wet the ice with at least a cup of water to improve the coupling of
the transducer to the i ce. P l ace the face of the transducer firmly on the wetted ice,
and you will now be able to see the depth displaye d digitally, and a signal showing
the bottom (and fish) on whichever sonar windows yo u have open. Drilling into the ice
1-2” before taking a reading may be necessary if the surface of the ice is very rough,
or if the ice is filled with air bubbles.

Operation

The VX-1i utilizes a combination of control knobs (Gain & Range) and keypad

- 4 -

Versa Electronics

www.marcumtech.com

(IR) and (ZM) to change or activate various system functions. The keypad has
an audible beep when the key is depressed to indicate that a system function
has been activated. The following is an explanation of the various system
functions.

Range Select

- The Range select knob is used for turning the VX-1i on or off,
as well as choosing the correct depth range. The VX-1i offers four depth
ranges to choose from that can be selected by rotating the knob clockwise.
The depth ranges are 20, 40, 80, or 160 feet. The depth-range setting is
determined by turning the unit on and turning the Gain knob looking for a solid
return (band of light) indicating bottom on the display. If no return is present,
then select the 40-, 80-, or 160-foot range until a bottom reading is displayed
on the screen.

Interpreting the different rings of numbers around the dial
When on the 20’ range, simply go by the white numbers. When on the
40’ range, use the outer white numbers, but multiply x 2 to determine
your depth [13 on the dial = 26 feet]. When on the 80’ range, use the
blue numbers. When on the 160’ range, use the blue numbers x 2.
The innermost numbers are for the split screen zoom, and they are
used in a similar manner.

Gain Knob

- The Gain knob controls the amount of sensitivity required by
the unit to pick up objects like bottom, weeds, fish, smaller bait-fish, or small
lures and jigs. The lower the number, the less sensitivity, conversely higher
numbers mean more sensitivity. However, too much Gain (sensitivity) will
result in too much information being displayed, and it becomes difficult to
interpret the return signals. The best Gain setting is achieved by turning up
your Gain from 0 until you receive a clear and steady bottom reading. If

looking for your lure or bait, turn up the gain until you just begin to

you’re
display your bait without it fading or flickering on the screen. The lower the
sensitivity, the narrower the display segments, the easier it is to distinguish
targets. We

cannot emphasize this strongly enough. Too much Gain will only
clutter the display with unnecessary information, making it more difficult to
interpret the return signals. Keeping the Gain at minimum levels will actually
provide you with the most accurate and precise information.

Interference Rejection

- The Interference Rejection system is designed to
knock out competing return signals from other sonar units being used within
close proximity. When other sonar units are causing interference to the display
of the VX-1i , activate the IR feature by depressing the IR key located on the
face of the VX-1i When you press the key, a beep will be heard. There are
multiple levels of interference rejection, and each press of the key will change
the level of Interference Rejection. The correct level of IR will be achieved
when the display is clear of display clutter. In some extreme cases, clutter will
be greatly reduced but not totally eliminated. It is recommended that only one
person in a group adjust the interference rejection at a time.

Zoom

- The VX-1i is equipped with a “bottom zoom” feature. When the ZM
key is depressed the circular display is divided in half. The right half of the
display (12 to 6 o’clock on the dial) will become the entire depth range (20, 40,
80, or 160 foot) you chose when turning the depth range knob to your desired
depth setting. This will be indicated by a red light at the zero mark (12 o’clock)
and another red light at 6 o’clock. These will be stationary and will not move
while in the Zoom mode. The backside of the display (6 to 12 o’clock) is the
other half of your split screen display. This is the Zoom window portion. The
VX-1i comes with a bottom zoom that displays the bottom 5 feet in an
expanded view. This expanded view of the bottom 5 feet is what is
displayed on the left side of the split screen display (6 to 12 o’clock). For the

be

Zoom to

activated, you must have a strong bottom return signal (Red) that
equals or exceeds one foot on the display dial. If a strong return signal is not
achieved (this can happen if fishing over a very soft bottom or when trying to
activate the zoom out of the water) the unit will not go into the Zoom mode. If
the unit will no t go into zoom mode, turn the GAIN up to 10, this will make the
bottom signal very strong. Once the ZOOM has been activated, turn the
GAIN back down to a normal operating level.

Signal Interpretation

Hard-bottom readings (rock or gravel) will be displayed by a wide band of RED
light indicating a strong return signal. Conversely, a soft bottom (mud or silt)
will return a weaker signal and will result in a narrower RED band or possibly
even a combined RED and ORANGE band. A soft bottom wi th weed growth
will often appear as a narrow RED or ORANGE band combined with both solid
and broken GREEN segments indicating weeds. Any fish in the weeds may
show as RED or ORANGE depending on fish size and relationship within the
transmit beam (in the middle or on the outside of the transmit signal).

Reading Bottom

- In interpreting depth, always read the leading edge
(shallowest side) of the signal return. If you have a strong signal return (wide
band of RED light) and it starts at 13 feet and ends at 16 feet, the correct
depth is 13 feet or the shallowest leading edge of the return signal. Anything
beyond the shallowest leading edge indicates the strength of the return
signal.

Reading Fish

- Fish will generally appear as sepa rate targets from the bottom.
A fish target can be displayed as RED, ORANGE or GREEN, depending on the
size of the fish and the location within the transmit beam. Larger fish located in
the center of the beam (cone) can appear RED and will be displayed as a
wider band on the display. Smaller fish or fish on the outside of the cone may
appear ORANGE or even GREEN. Fish moving through the transmit beam may
change color as the return signal strengthens or weakens reflecting their
location. Fish that are right on the bottom can appear as part of the bottom.

best indication of a fish sitting right on the bottom is that the leading edge

The
of the bottom return signal is either ORANGE or possibly a dithering or
flickering RED segment. It is important that the GAIN or sensitivity be kept to a
minimum when displaying a strong bottom return. Too much GAIN will flood
out the ability to differentiate targets and clutter the display.

Reading Lures or Bait

lures or bait. When tuning the unit to display your lure or bait, lower the object
to the desired depth and turn up the GAIN until you see the lure or bait on the
display. It is important that the GAIN be set so it displays the lure or bait as
you raise or lower it.

NOTE: Too much GAIN will cause clutter and may make it difficult to
distinguish other targets like fish near the bottom. When tuning the unit to
display lures or bait, make sure that the objects are in the center of the hole
and therefore in the center of the transmit beam. If there’s water current (some
lakes have underwater current or movement) and the lure doesn’t weigh
much, it may move to the outer edge of the signal or out of the transmit beam
altogether. This will make it difficult or impossible to pick it up on the display.

- The VX-1i will pick up and display small objects like

Dead Zone

This occurs on sharp drop-offs where the transmit beam (cone) hits the
shallower edge of the drop-off and returns before the deeper edge returns.
This in effect creates an undisplayed area between the shallower and deeper
water within the transmit beam.

Open Water Set-Up

The VX-1i is an excellent sonar unit for open-water use. To convert the VX-1i
from an ice system to an open water unit, remove the VX-1i powerhead from
the electronics shuttle. A new gimbal bracket is supplied with the open water
transducer kit and can be mounted on any flat surface. The unit should be
mounted in a location that is free from other electrical apparatus to eliminate
interference. If interference is observed, reposition the unit until optimum
performance is obtained. Your boat’s 12-volt DC electrical system can be
used to power the unit.

The VX-1i is protected from accidental polarity reversals. No damage will
result from an incorrect battery hook-up. The ice-fishing transducer supplied
with the Ice System is not designed for open-water use. There are two trans­ducer choices for use in open water. The high-speed transducer is designed
for transom mounting (outside the hull) and reads depth while the boat is on
plane. The puck-style transducer is most often mounted on the bottom of a
trolling motor or epoxied into the hull of a fiberglass boat.

High-Speed Transducer Installation

High-Speed transducers are designed to be mounted on the transom of a
boat. If properly installed, you will be able to read depth, weeds, and fish while
the boat is on plane. Transducer mounting location is critical for optimum
performance of the VX-1i sonar unit. The mounting location should be free of
any white water or turbulence resulting from rivets, ribs or hull strakes. It
is preferable to mount the transducer at least 18 inches from the centerline
of the boat to avoid turbulent water resulting from the outboard motor. The
transducer is wedge-shaped and should be mounted with the leading edge
mounted against the transom. The leading edge of the transducer should be
mounted flush with bottom of the boat. This can be best achieved by using
a flat object like a ruler and holding it flat along the bottom of the boat and
matching the bottom of the transducer to the bottom of the boat. Attach the
mounting hardware to the high-speed transducer as shown in the instructions

- All sonar units will have a dead zone in certain circumstances.

included with the transducer. Hold the transducer, with attached mounting
hardware, to the transom of the boat (flush to the bottom) and mark the center
of the holes on the transom. Drill the appropriate-size holes and attach the
transducer to the transom. Tilt the rear of the transducer between 2 and 5
degrees below the transom to ensure solid contact with the water when the
boat is on plane.

More-detailed installation instructions are included with the high-speed
transducer and mounting hardware.

Puck Transducer Installation

Puck-style transducers can be mounted on the bottom of a trolling motor,
epoxied in the hull of a fiberglass boat, or mounted to a suction cup for
portable use. Mounting to a trolling motor is achieved with the use of a large,
adjustable stainless steel hose clamp available at most hardware or
automotive stores. Slots are included in the puck transducer for passing the
clamp through and then around the motor. Align the transducer so that it is
perfectly centered from right to left on the bottom of the motor. If the
transducer is tilted or angled, you won’t receive a signal on your sonar display.
Do not mount the transducer next to the propeller. Turbulence from the
propeller may cause disruption in the sonar display. In-hull mounting is
designed for achieving high-speed sonar readings in fiberglass boats. For the
best readings, the transducer must be mounted in the layer of fiberglass that is
in direct contact with the water. This is best achieved by mounting the
transducer in the area surrounding the bilge pump in the transom area of the
boat. Some boats have false bottoms or floors. Mounting the transducer in a
location not in direct contact with the water will result in dead air space and no
sonar reading. Once the correct area is located, the transducer is installed
using a good grade of marine epoxy. For more-detailed installation
information, refer to the directions included with the puck transducer.

The VX-1i has a current draw between 250 and 300mA per hour. With a
standard 7.2-amp hour battery, the VX-1i should last between 18 and 22
hours if fully charged. To extend the battery life, recharge the battery after
every use.

Cone Angle Coverage

The cone angle of all VX-1i transducers is 20 degrees. The approximate area of
coverage with a 20 degree transducer is determined by dividing the depth by 3
