I wouldn't even consider sitting there waiting for a shot.
Wrap everything you want to keep. They'll move on when there's nothing left available.
I wouldn't even think about setting a Conibear on land; they aren't forgiving at all. Your dog can be a perfect gentleman, staying by your side and still get caught in one. The only exception is the smallest size; 110 or 120, which we used to set in cubby traps for marten until it became illegal due to the Canada Lynx.Conibears are easy and deadly for beavers. But when set on dirt, they will catch anything...raccoons, otters, coyotes, dogs, cats, turtles. So you have to be careful where you use them. Also check your local laws. But I was a beginner trapper, and quickly learned to trap beavers with this effective trap.
