Thermoelectric works. The bears don't seem to care. Act like you're a part of the landscape. Don't move if you don't absolutely have to. Make sure your clothes and raingear are quiet. The ears often circle the bait before coming in and will hold just inside the trees and look things over. They know you're there. If they don't see you as a threat in They come. If you can use the same bugs pray as the person doing the baiting so good. That smell means snacks. Above all have fun.
