There`s a lot of fun to be had in fishin at night,I always figured thats when the big ones come to surface to chow down.Tip ups,the setlines of the ice ponds set up with the proper bait for the fish You want to catch then sit back and drink a lot of beer and whiskey and every 1/2 hour or so run the circuit and see how many tipups ya got with the flags flying.not much to doin that and ya dont need some kind of underwater lantern so the fish can see the bait,They`ll find it.
