Abstract: Losing your best/favorite reel and rod while fishing, is devastating. I have lost a few. I have observed other fishermen losing reels and rods also due to fish pullover. The fish were literally taking our reels and rods. I said, “There has to be a solution.” I began experimenting with many items from boat holders to bungee cords; from hard materials to soft materials and spikes to rope tees. Nothing worked until I put together The Barge Assistant Rod Saver. The Barge Assistant Rod Saver consists of: a hook, link chain, screws, washers, holding nut and a round weight. This was designed to prevent immediate rod pullover on a fish initial strike. The results were astonishing. The Barge Assistant Rod Saver allowed me time to get to my fishing rods before losing them. I have not lost a rod as a result of using The Barge Assistant Rod Saver.
