"Basic" in the sense that there is no riser pole included with other machined parts (yes, we have a pontoon control screen mount that has more sophisticated features on this same page here:  https://www.fishfindermounts.com/product-page/pontoon-rail-control-screen-mount ), just a great robust solution with the capability to rotate your screen via the swivel mounting plate attached directly to the pontoon rail clamp.  This is a great way to get your 4-9" screens mounted onto your pontoon boat (or round rails if your boat has them) if you don't want to screw into your console, don't have the room on your console or you rent pontoon/other  boats with rail systems.  Another rock solid control screen mounting solution for your pontoon boat from Fish Finder Mounts .com!
