This is what I have found when fishing for perch in deep 35+ water, the ice is covered in a foot of snow so there is very little light that makes it through. When test drilling holes looking for active fish, I bring a piece of foam with a 1 inch hole in the middle to allow for me jig. I have found that active perch will come off the bottom much more aggressive then if I jig with covering the hole first. This doesn't mean that I get any takers it just tells me that the light spooks the fish in deep water.
That's why to me it seems that setting up fish house to be able to have the best shot at catching active biters in deep water.
Also being mobile is your best bet when searching for perch and the snobear is the ultimate vehicle
It's been a few years but I have managed to find some bigger schools of hungry perch but I can only seemed to get them to follow the lure up off the bottom either under the fljlover or with my foam circle covering the test hole.
