Introduction
Thank you for purchasing the MarCum LX-3TC multicolor sonar unit. The
LX-3TC incorporates the latest in sonar technology, featuring a patented
flexible zoom that can be set anywhere between surface and bottom, a patent
pending TrueColor display, 2000 watts of peak-to-peak power, patented signal
interference rejection and target separation down to 1 inch. 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 LX-3TC system.
Only by reading this manual can you realize the maximum benefit from your
purchase — enjoy your new LX-3TC sonar system!
General Description
The LX-3TC multi-color sonar unit utilizes three different colors within its
display to differentiate between densities of objects. Each of the three colors
is represented by a separate LED on the display board. This new patent
pending TrueColor display eliminates the blending of two colors to make a
third and results in an ultra-crisp display that greatly enhances target identi-
fication. 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 LX-3TC offers 12 levels of signal 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 LX-3tc offers a Zoom feature that allows the user to hone in on a specific
section of water within the water column. The Zoom window (area of water
being selected) can be set at either 5 or 10 feet on the 20- and 40-foot depth
range, 10 or 20 feet on the 80-foot depth range, or 20- or 40-feet on the
160-foot depth range.
This allows for a larger Zoom window to be viewed on the deeper range
settings. The Zoom window can be moved anywhere between the surface and
the bottom by use of the UP / DN arrow keys located on the keypad.
The LX-3TC 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 trans-
ducer 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 your Marcum be allowed to be in direct contact with water, and if it
does get wet, every attempt should be made to get your system dried off as
soon as possible.
