Can’t see….

I have one of these as well (Orvis Dropper Box). It lets you tie several three nymph rigs at home instead of tying all of those knots on the stream. You waste way less fishing time and you don’t have to struggle as much with seeing.

These save me a lot of time when at a stream fishing. Tie one knot and you have a 2 fly ( or more) rig attached.
