Johnny Ray Fish Finder Mount JR-300 - Portable Swivel Bracket

Our review of the Johnny Ray JR-300 finds it is a practical, no-nonsense swivel mount for anglers who need fast removal and flexible positioning of fish finders. The single biggest reason to buy is the push-button quick-release combined with 45 lock-in positions and full 360 degree rotation, which together let one person change viewing angle or stow electronics in seconds. Built from DuPont nylon with stainless steel springs and screws, the JR-300 targets boaters who want a sturdy bracket that supports common models and handles the knocks of regular marine use.

Key Features

• Push Button Release: Lets the user remove depth finders quickly for storage or security without tools, saving time at the dock.
• 45 Lock Positions: Provides precise incremental stops so the screen stays at the chosen angle even in choppy water.
• 360 Degree Rotation: Allows full swivel for sharing the display between bow and stern or adjusting for glare.
• Durable Construction: DuPont nylon with stainless steel springs and screws offers corrosion resistance and long-term reliability in a marine environment.
• Wide Compatibility: Works with many top brand fishfinder heads and chartplotters when used with the appropriate adapter plate as shown in the compatibility images.
• Strong Support: The mount reliably supports devices up to 7 lbs, accommodating most portable fishfinder units and small chartplotters.

Who It's For

This mount is best for freshwater and inshore anglers who use portable fishfinders or smaller chartplotters and want quick one-handed removal and flexible viewing. It suits boat owners who prefer a compact base that can be locked at many angles and rotated fully to reduce screen glare or to hand the display to a fishing partner.

It is less appropriate for heavy electronics beyond the stated support weight or installations that require permanent, vibration-isolated mounting. If you need a large, fixed heavy-duty pedestal for a multi-unit console, look for a heavier dedicated mounting system designed for larger displays.
