RAILBLAZA Fish Finder Mount R-Lock S

The RAILBLAZA Fish Finder Mount R-Lock S is a purpose-built cradle for getting your sonar or chartplotter exactly where you want it, and keeping it there. It's a three-axis mount with friction joints top and bottom, and RAILBLAZA's R-Lock lockable joints do the real work. Set your angle, lock it down, and the display stays put whether you're idling on a flat calm morning or pounding through a chop on the way back in.

The center joint adjusts in 15 degree increments, so dialing in your viewing angle is quick and repeatable. You're not fighting a floppy ball head that slowly creeps out of position every time you take a wave. The friction joints hold, and the R-Lock backs them up. For anyone who's watched a fish finder slowly tilt toward the sky over the course of a day, that's the whole point.

It's compatible with fish finders and chartplotters, which covers most of the small to mid-size displays boaters actually run at the helm or up on the bow. The footprint is compact, just 4 inches wide by 4 inches deep, and it sits low. That low profile matters more than people expect. On a small tiller boat, a kayak, or a tight center console, you don't have room for a mount that eats half your dash or blocks your sightline to the water. This one tucks in close.

The body is molded from UV stabilized fiberglass reinforced plastic. In plain terms, it's built to live outside. Sun, salt spray, rain, and the constant flex of a boat working through waves, this material shrugs it off without going brittle or chalky the way cheap plastics do after a season in the weather. The black finish disappears against most consoles and dark decks instead of shouting for attention.

Who's this for? Kayak anglers who want their finder angled up toward them while they're seated low. Small boat owners rigging a helm and adding electronics. Anyone running a portable or second display who needs to reposition it depending on where they're fishing that day. The three-axis adjustment means you can point the screen at your seated position, then swing it toward a buddy, then lock it back. That flexibility is what separates a good mount from a bracket you screw down once and resent forever.

Install is straightforward. The compact 4 by 4 base gives you a stable footprint on a flat surface at the helm, on a console, or on a gunwale. Once the base is set, everything above it is adjustable, so you're not committing to a single fixed angle the day you rig it. Get it roughly where you want, then fine-tune on the water with the 15 degree increments and lock the R-Lock joints.

A quick note on what this is and isn't. It's a display mount, sized for fish finders and chartplotters in the small to mid-size range that dominate helms on boats under about 25 feet, kayaks, and jon boats. It isn't a heavy pedestal for a large glass-bridge display, and it isn't a transducer mount. If you're mounting a compact sonar or a combo unit and you want it locked, adjustable, and low profile, this is squarely in its wheelhouse.

RAILBLAZA builds modular gear for boats, and this mount fits that philosophy. It's versatile, it's user-friendly, and it's made to be adjusted and re-adjusted for years without wearing out. If you've been running your finder on a wobbly bracket or balancing it on a seat cushion, then the upgrade to a solid locking three-axis mount is one you'll really notice the very first time you take a wave and the screen simply doesn't budge.
