If you go with connibears you will need 330’s which is the big boy. Make sure you watch a lot of instructional videos or have someone show you how to SAFELY work them. They break whatever they hit. There are several veteran beaver trappers on here. I asked k bush 100 questions and he got me catching beavers right a way

See if you can find the dam and do a simple dam break set. Or slides and do a castor mound set
