you guys, as someone who has to check depth manually EVERYTIME, not just to verify. I can promise you there is a better solition then your hemostats and various aligator clips. I just use an old spool of floro that I keep rigged in the tube. bare hook on the end, hooked into one of these. or to keep it even simpler you can just hook onto your dropper, send it down to the bottom, grad the leader at surface level and set you bobber 6"-1' shallower. fastest way ive found to dial right into the bottom in 20-30ft of water.
