Bug, the egg trap is no way like the coon cuff,other than it is considered a dp.
Special tools are needed not only to set the egg trap, but they are also needed to remove any catch. They are also not the easiest to set.
These are the main reasons you have never seen any egg traps,they are at the bottom of the totem pole,as far as dp's are considered.
They do work,it's just that the others are easier to use.
