each time you move locations, depending on the depth and
bottom composition.
Signal Interpretation - Sound waves emitted by the LX-3
bounce off targets and return with the strength of the targets’
density. Denser targets return with a stronger signal, displayed
as RED. Less-dense objects (small fish) return a medium-
strength signal, displayed as ORANGE. The least dense objects
(weeds, bait-fish, lure) return a weak signal, displayed as
YELLOW. Objects on the edge of the sound cone may appear
as yellow. A fish moving through the cone may appear first as
yellow, then orange, then red, depending on its size and how
close to the center of the cone it moves.
Using the Ice Transducer - The weighted transducer suspends
in the ice hole from the adjustable ice arm. The shuttle system
does not have to be on a flat surface for the transducer to hang
straight. The self-aligning transducer hangs like a plumb bob and
always transmits and receives a direct signal. The transducer
should be positioned just below the water line, except when the
ice begins to get thick (more than 24 inches). Once the ice gets
thicker than 24 inches, ringing off the side of the ice hole can
occur. This is usually displayed as a solid band of light between
2 and 3 feet on the display dial. If this occurs, lower the trans-
ducer to the bottom of the ice hole. This should eliminate most
display clutter.
Battery Draw - The LX-3 has a current draw between 300 and
350mA per hour. With a standard 7-amp hour battery, the LX-3
should last between 18 and 22 hours if fully charged. To extend
the battery life, it is preferable to recharge the battery after
every use.
Cone Angle Coverage - The cone angle of all LX-3 transducers
is 20 degrees. A general rule of thumb is that the coverage (dis-
tance across the signal beam) is 3.5 feet per 10 foot of depth. In
10 feet of water, the coverage is 3.5 feet; at a 20-foot depth, the
signal beam is 7.0 feet across; and in 30 feet its 10.5 feet
of coverage.
