Mark,I just looked at how you set your traps,again.I noticed(funny I didn't catch this before) you set with your trigger on top.I flip that baby over and go with the trigger on the bottom.The trigger is bent into an -m-, and when the 330 is half submerged,the beaver has a clear,open window to the mound.Nothing whatsoever to impede it,from getting to the mound(or so they think).
