Gain Knob
- The Gain knob controls the amount of sensitivity required by the
unit to pick up objects like bottom, weeds, fish, or 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 you’re looking for your lure or bait, turn up the gain
until you just begin to display your bait without it fading or flickering on the
screen. The lower the sensitivity, the narrower the display segments, and
therefore 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 LX-5i, activate the IR feature by depressing the IR key located on the
face of the LX-5i. When you press the key, a beep will be heard. There are 12
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 Zoom function can be activated by depressing the ZM key. An
audible beep will indicate that the Zoom function has been activated. The
Zoom function divides the circular display screen in half. The right half of the
display, (12 to 6 o’clock on the dial) will become your entire surface-to-bottom
display. This will be indicated by a RED band of light at the top (zero) and a
RED band of light at the bottom (or 6 o’clock). If you are on the 20-foot depth
range, the 12 o’clock position will be the surface of the water and 6 o’clock
will be the bottom of your chosen depth range (20 feet on the 20-foot scale).
When utilizing the Zoom function, you will be reading your depth markings by
viewing the inner circle (YELLOW numeric) located in the center of the LX-5
display dial. If you select the 40-foot scale, the same applies, except you
multiply the YELLOW numeric markings by 2. The 80-foot range setting is a
multiple of 4, and the 160-foot range setting is a multiple of 8.
Once you use the LX-5i a few times, your brain will automatically make the
adjustment without any noticeable thought process. The backside of the
display (6 o’clock moving clockwise to 12 o’clock) is the other half of your
split-screen display. This half reads what you see on the right half, but in a
magnified version. This will greatly enhance the precision of your presentation
and show that multiple smaller targets might exist on the left half (Zoom) where
it appears that one larger target is showing on the right (normal display). You
can determine the size of your Zoom window (the width or amount of water
viewed within the water column) by depressing the ZM key. If you
