INTERFERENCE REJECTION EXPLAINED
The purpose of interference rejection is to reduce cross-talk interference from other nearby depth sounders. This can be very helpful if you have
another sounder mounted on your boat running at the same frequency as your asher. It is also helpful when other anglers are running sounders
operating at the same frequency as your asher nearby.
Cross-talk interference occurs when the signals sent from one depth sounder are received by another. If the two sounder’s frequencies are the same,
each unit is unable to dierentiate between its own signals and others. What you see as interference is actually the reading of the other sounder
displayed on your screen. The signals can circle around the display or remain
stable. Beware of the stationary interference signals. They can lead you to
believe the depth is dierent than it is or that there’s a sh hanging below
you which really isn’t there.
Usually, when you see interference on one sounder, the other sounder will
show it too. Therefore, when you use your Interference Rejection to reduce
or eliminate the interference on your display, the other sounder will see
a similar reduction. This means you can use your Vexilar asher next to
another sounder which does not have the I.R. feature and both sounders
can run more clearly.
If two Vexilar units are operating together, you will get the best results
by leaving the IR setting at one level on one unit, while adjusting out the
interference displayed on both units using the second unit’s IR feature.
Interference occurs when the cone angles of two different sounders
operating at the same frequency intersect. It can also occur if the
sonar signal from one sounder bounces off an underwater object and is
received by another sounder.

VEXILAR ICE FISHING
The Vexilar FL & FLX series color ashers oer
distinct advantages over LCD depth sounders for the
sport of ice shing. This unique style of shing oers
a stable platform to sh from. Because everything is so
stable, the only movements below are that of sh.
Additionally, the conditions allow you to drop your bait
directly down into the center of the transducer’s cone
of sound. This allows you to be able to see your bait
and the sh on the display at the same time. You can
tease the sh and see his reaction in real time.
With practice, you will soon be able to judge for
yourself both sh species as well as the mood of the
sh, and whether your lure presentation is working or
not.
Please Use Caution
Before venturing onto the ice to go shing, be sure
you know if the conditions are safe. Check with the
local bait shops AND cautiously check the ice thickness
yourself. You should have at least 6” of clear ice to
safely support yourself and your ice shing equipment.
