L.H.--I learned to trap beaver with footholds,I have use #3 coils,and also the 4 and 14 jumps,and the newer 7 1/2 inch coils.While I did very well with footholds,it has been several years since I set one for beaver.
I have gone to 330s exclusively. Now some will tell you that you must also use snares and footholds to be effective.To This I say-"-Baloney".
If a person uses one tool for everything,they come up with ways that others never think of to make sure it produces.
I have worked for many years perfecting my methods.I find 330s are just faster and easier for me.Now I am not trying to put down the footholds or snares--it is just that the 330 is my choice for beaver and otter. Tom
