They work great for mako baits. Tie the clip to a bleach bottle and set your baqit at desired depth and it slides up the line at the bite. Texas mako technique

I use them to clip rubber bands on my plannerline. Also to keep the outrigger haliards from slipping.

And of course, on my diving duck decoys.
