I got out to a local beaver pond to try my luck. I'm trying something different this year and set a 330 as a bottom edge set. I saw Bob Noonans bottom edge mink video and he mentioned that this set was very effective on beaver as well. Here are a couple of pics. Hopefully you will be able to see them without too much glare.
This is the beaver pond. After the 4 inch snowfall we had yesterday, it's melting real quick.
