first and foremost , that comment about the bank den will get you a citation , house , lodge , or den is all the same . stay back , if you can cath them at the lodge you can get them 100 s of yards away .
the loop i use is about 7-8 inches
as far as snare or cable restraint , anytime you put entanglement into the set either one will become a snare which could prove deadly . im using snares , 1x19 cable with a bent washer lock , no BAD . these ones are loaded , but i have used ones that were not many times . once you get a beaver committed to swimming in he is done , no hitting the brakes to back out .
great to see the replies and questions . snares are the best tool ever for beavers . 99.9 percent of them will be alive when you check which lets you let any kits free . the weight as compared to footholds or conibears is miniscule , they fit in a pocket . i wire off with 14 gauge wire that i double up , can wrap around anything . lots of people have asked ... cant the beaver chew that sapling you are tied off to down , well the short answer is sure , however they lack the brains that it would set them free . a root , sapling or tree all works . the added advantage is seeing your catch alive , that is the nice thing we all like with land critters . most times when i approach the beavers are just sitting on land waiting . if anyone else wants to chime in feel free , or if anyone has questions ask . thats what we are all here for , to learn and teach .
