Like Vaseline a light coating of wax where the dog and pan meet works wonders on rusty traps. If used make sure your middle finger is pressing hard on the pan when setting. Ted
I know I am not the sharpest tack in the box but I have never had good luck with OOS, I up graded to the SS pan and dog. Just think the pan tension is very hi. It takes a lot to set if off. JMO.
It does take a bit to set it off. That’s why you have to bed your traps well. If you don’t jam the scissor legs in the ground then you run the risk of the trap being pushed up and out of the run without going off. I set mine so the trigger pan is about 1/2” off the bottom of the run. The mole faceplants into the trigger pan and then tries to dig under it, setting off the trap. I rarely miss them in the OOS traps.
