Your sounder's bolted in one spot and you can't reach it without unbolting everything. Or you've got a bracket with weird hole spacing that doesn't match any off-the-shelf mount. The 102mm Rotating Platform locks into any StarPort, spins a full 360°, and gives you a flat surface to drill your own bracket holes exactly where they need to be. UV-proof engineering plastics. Stainless steel screws. Pop it on your inflatable, kayak or sailboat, lock it in, pull it off when you're done. The StarPort stays put – you just swap what sits on top
