trap setter, the coon cuffs fits nicely into end of a section of PVC pipe, just cut a notch for the swivel/chain to allow the trap to fit inside and. I shove the PVC pipe into the creek bottom and angle it back to the edge of the bank. This is good where a hot trail is right along the edge of the water...the PVC has a lot of eye appeal. But, it also sticks out like a sore thumb so be careful if you are concerned about others in the area seeing your set.
trails that run along a sheer bank you can just dig into the side of the bank like a pocket set and put the coon cuffs into the hole. I like the trigger design on the coon cuffs for this type of set as the triggers must be "pushed" rather than "pulled" (as they are on the Duffers DP model) so the coon sets the trap off as it is reaching into the coon cuffs. You can get away with liquid lure, fish oil, etc with this set up as the coon will keep reaching but not get any baits for its effort and you get a good catch ratio. You can run this on a drowner or use a stake, or an earth anchor, etc. too.
I also painted the face plate black on a few of my coon cuffs to give them a little more eye appeal. The little hole isn't much of an attractor in itself so you need to put it right on location, and use a good stout food lure to get them to reach into the hole to get.
I've taken quite a few possums in mine also so don't discount it as a possum taker. I think the possibilities are endless. I've seen them in the end of PVC pipes that are wired to an overhanging limb with coon sign on it. I've wired mine to sides of fence posts where the fence post was the "highest" and "most prominent" object in the area near a stock pond and took coon that way with it. They seem to prefer to check things out a little from high points nearby. that might not work everywhere but was good for me.
However you use them, just make sure they are stabilized enough to get fired by a reaching coon and not "played" with if you just set them along a trail.
These traps are a little pricey new, but with care they last forever and are a very efficient tool.
