Fish a lot at night and like to set my tip ups spread out pretty far, so sometimes it's a few minutes before I get to a flag. Many times the fish has dropped the bait by then so I was thinking going about 10 ft above the depth I like to fish at and cinch a rubber band on the line then loop it over the spool, then reel up the spool to the depth I wanna fish. This way the fish can take 10ft of line to make sure it's eating the bait then the rubber band will set the hook, probably would work great with circle hooks. If it's a big fish the rubber band would break and let the tip up free spool. Any one ever try this? Can't see why it wouldn't work
