The Absolute Original. The Fish-On! Rod Holder set the standard for adjustable rod holders, and continues to lead the pack. With well over a MILLION rod holders sold, the Fish-on! Rod Holder is in a class by itself. It is supremely adjustable, with 360 degrees of horizontal adjustment, and 90 degrees of vertical. Designed with an enlarged opening, just the act of removing your rod creates a hook setting motion. It features a sliding locking ring to secure your rod, and comes equipped with a side mount ready for installation and use.
