Ok, I understand the concept of the basic dirthole set. Lure on the backing, hole with or without bait, trap in front of hole. Target animal steps on trap while investigating the hole. Now onto the flat set. I see there is also a backing, but no hole. So is the backing getting the lure? Where is the trap bed? What is the concept with this type of set? What's the difference between the flat set and a post set? How do you get the animal to approach the correct side of the backing? Would like to ad d this set to my arsenal this year as I am going to be k9 trapping pretty hard, and would like to know the hows and whys of this set. Thanks! Chris Wanna kill these ads? We can help!
