Do electronics affect fish?
Nope, motor noise, boat movement, or they just moved on their own (they often do that you know They're not far away.
I know from experience that boom shockers affect fish.
I dont worry about it though when I fish.
... maybe it depends on the lake and how much traffic it bears?
lakes around hear are multi-use lakes and busy, and fish still get caught
ice fishers with flashers/finders would probably think ...not so much
