I like the Frabil circle ones.Dont freeze up as bad as others.The orange ones are good you get a 50/50 shot of snowmobiles running them over.

Ive seen enclosed boxes with a candle in them and sensor lights..

If the hole is freezing up make a little channel from the tip up hole. Get a coffee can put some charocal in it lite it up, should keep hole from freezing up.

Seen Canadians use branches, that was differ..
