Have been given some Magnum bodygrip 116's, and having not used them before, am wondering what the benefits are , if any , over the Mk6 Fenn trap, which I use regularly for squirrels and the odd rabbit etc. It seems that while the Fenn operates in a horizontal plane and is very stable, the bodygrip when set , is in a vertical plane, with only a small base area, and could be knocked over or moved if brushed against. I know both must be used in tunnels. Any opinions ?
