Setting Sensitivity for Ice Fishing
The IceMachine's basic operation is pretty easy, right out of the box. If
you're a sonar novice, try operating the unit with the automatic factory
default settings until you get a feel for how it's working.
As you're learning the basics however, Sensitivity is the one important
setting that you should adjust while ice fishing. We strongly recom-
mend you try the following method for "tuning" your sensitivity to
match the current water conditions. It will help you see your bait, cut
through any clutter in the water and dramatically show fish when they
move in to check your offering. As you learn to interpret the signals on
the flasher screen, you'll be able to modify your presentation based on
how fish react to your lure.
