The Supski Mobile Fishing Platform, the newest must have for your fishing gear, is an HDPE plastic sheet which has holes running the perimeter of the platform for bungee cords to hold coolers and tackle boxes in place. In between the anchor holes are brass 1/4-20 inserts designed for attaching fishing tackle and other accessories for fishing and leisure activities. The Mobile Fishing Platform takes up very little space in your vehicle. The mobile fishing platform sets up quickly and in a very short time you're ready to fish.
