Off Shore Tackle Stacker Downrigger Releases allows you to run two lines off of the same downrigger. After the first single line has been attached off the to the cannon ball using a standard single release, lower the cannon ball a distance then attach the snap (to protect from loss of the stacker) and the release which is on the short leader to the downrigger cable to hold the stacker in position. Then set the second fishing line in the release on the long leader. Attach the clip to the downrigger weight and place the line in the pad. The soft pads won't damage or fray line. Tension is adjusted based on how far you place the line in the pads.
