I have the scotty elec. with 60" booms. This last year I tried the scotty weight retrievers, they are great!!. They are simply a sleeve around the DR cable, and a cord attached to the sleve. The cord is pulled through a small clench chock, and the ball is held close to the boat  within easy reach. I mounted the clench chock on the side of the scotty swivel mount, a very convienient location. I have noticed a significant increase in tending speed. IMO  swivel mounts are not for tending, only for transport.
