I'm betting 90% of all trappers never ever tuned a 330. Then they blame the trap.

I think a lot of misses that get attributed to target critters setting off the trap are from other things - fish, small turtles, random junk bumping the trigger. Lots of things can set off a 330 and not get caught in it. A well adjusted BG will fire with very little trigger movement - most catches will be right behind the head to right behind the front legs with the trigger set in a V. If you L the trigger or twist the wires together and push them to one side you will get more catches farther back. One thing about playing with the triggers to avoid otter, it may work OK where there aren't a ton of otter but my experience in the southeast where we have a ton of otter is that you will still catch a bunch of otter. If there are multiple otter going through that trap each night the law of averages says one will bump the trigger, and they do. I have hundreds of large body grips, they all get set some time during the season. Each and every one of them gets set and checked for proper adjustment before season and if one gets roughed up during season it gets swapped out and thrown into the repair pile. I like the Terminator replacement trigger as they are tension adjustable which comes in handy when setting a fast flowing stream and the trigger wires are stainless steel, super easy to bend if needed and next to indestructable. I hate the trigger on Belisles - the wires break way too easy. The trigger body is OK, but the wires are the worst. My arsenal of BG is a hodgepodge of things - Duke, Sleepy Creek, Victor, Belisle, Bridger - they all kill beaver and otter fine as long as the springs are strong and the trap is properly adjusted.
