The Scotty 166 gives you a solid 1.5" ball system base for mounting 7–9" fish finders to nearly any surface. Engineering-grade nylon shrugs off UV exposure while stainless steel hardware resists the corrosion that salt air delivers. The 1.5" ball joints deliver a full 360° of rotation and 180° of tilt at both ends, so dialing in your display angle takes seconds. A multi-hole top plate spans most popular electronics brands, and the easy-grip T-knob locks everything down tight when conditions get rough.
