Was out yesterday, stopped out for some lamping and checked the snares again when the light faded... Another two out of the runs, one foul caught, ample room left for feet clearance, sometimes the rabbits commit to these points and jump clear through without touching anything, hence waist caught, you could try and counteract this by raising even higher, with a loss of killing area, risking a rabbit slipping under or knocked snare... Peoples opinion would differ.
