I did alot of river trapping and would use floats when the shore line would start to ice. Mine were triangular and I would set two traps on the open downstream end and use apple for bait. Had to anchor them well as I'd catch a couple of beaver in them every season. I used 1 1/2 coilsprings on them and would catch rats, coon, mink and beaver on them.
Bank hole were always good rat, mink and coon getters. Caught a lot of rats when baited with rat carcasses.
