The RAM ROD® Jr Fishing Rod Holder, compatible with both spinning and casting reels, is specifically designed for light-duty environments and smaller fishing rods. It features a flexible latching strap to secure your rod. A hexagonal attachment point makes the rod holder compatible with the C-Size and B-Size hex ball bases. This configuration includes a short spline post. The RAM ROD® Jr is also GoPro® compatible – just attach your GoPro factory mount directly to the rod holder or use the Double Ball Mount to attach any action camera. If you want to mount your phone to utilize your mobile fishfinder app, use the Double Ball Mount with X-Grip®.
