Gills are right under you hole, just not biting your offering. Are you using electronic? Are you fishing early and late?
Drilling holes like a Texas oil tycoon,I use a troller ,but somehow they seem to be elsewhere.
Not sure what a troller is. ( Marcum ice troller,)thanks for the info,I will give it a good effort to find them.
There is a small local lake I fish that you can drill 200 holes and spend all day looking and never mark a fish. But show up at 8-9 o'clock after dark, and it's a slamfest of hogs.
