On an earlier discussion on hard setting traps. I broke these out to take a picture. I got them on a Bridger #3 i'm getting ready to wax. These "setters" fit the dukes. But with a little modification, will fit the Bridgers. I'm going to mod them to fit those 650's and keep them in my bucket in case I run into trouble in the field. They do work well. I just have not needed them until these 650's.
