The Off Shore Tackle OR39 Sam's Pro Releases are very popular with anglers that troll with braided line. This release allows you to trip your board/rig to release with braided line. Many anglers use this with mono as well. It can be attached to the tow arm rigidly with the provided lock nut or loosely with the split ring. If the split ring is used, these will work with most inline boards on the market. Sold per each.
