It depends on where you are located, when your season is and how much if any snow you have on the ground in your season.
I have incidentally caught more fisher at dirthole sets made for canines and lured with a skunky smelling lure than I can remember counting so I know that is a good set before snowfall.
Generally speaking, there is a considerable snow on the ground here in fisher and marten season and trappers either prefer cubbies guarded with a body grip trap or leaning poles above snow line with a body grip trap. Skunky smelling call lures are great on both fisher and marten and trappers in my area generally use beaver meat as a bait along with the lure. Ace
