A great release is more important than the downrigger itself !
Try my improved Pro Release II, you will love them, guaranteed!

The Pro Release II was designed to release smoothly and predictably at any tension setting using a unique "pinched bobbin" design.
A few wraps of the line around the bobbin, pressing against the rubber wheel provide rod loading tension
Thumbnut adjusts release tension from less than 0 all the way to 20 pounds of pull.
It's unique design is perfect for braided or monofilament line.

The Pro Release II has the following key features:
Proven design from 1977, was very popular, but disappeared after 9/11. I started this biz to bring the best back for you.
Best product at the best value for what you get, one release does it all.
Eliminates false releases through precise rod loading / release tension adjustment
No tools required
Complete and ready to fish and stack out of the package
Simple loading. Lay the line on the bobbin and wrap 3-4 times for rod loading
