I fish often for hybrids, and with hybrids I have watched many times where once one fish is pulled from the school they get lock jaw….until you turn the FFS off. You can watch them approach and follow, but they will not commit after that first fish. What I do now is scan and mark them, pause the unit, and cast/catch. I will periodically switch back on and pan, but the unit is paused during casts/retrieves. That approach makes a noticeable difference for me, and I was never really a fan of video games anyway so I’m fine with it 😉.
The tech is definitely a game changer as I can “see” what I had previously only deduced from partial data. I would agree that in my experience crappie don’t seem to be affected by it at all.
