Replacement for RAM-109HU Universal Horizontal 6ft Swing Arm Mount

Our review of the Replacement for RAM-109HU finds it is a straightforward, heavy-duty option for anglers and boaters who need a reliable, adjustable mount for chartplotters and fishfinders. The bottom line: this mount is for users who want a corrosion-resistant, stable arm with wide compatibility across Garmin, Humminbird, Lowrance and Raymarine units; its dual 360 pivot points and 6' swing arm make achieving the ideal viewing angle easy even from different seating positions. If secure attachment and long-term saltwater durability matter most, this mount delivers.

Key Features

• Universal Compatibility: Works with a broad range of Garmin, Humminbird, Lowrance and Raymarine fishfinders and chartplotters so it fits most popular heads without adapters.
• 6' Dual Pivot Arm: Two independent 360 degree pivots at the base and the swing arm allow full horizontal adjustment for optimal screen visibility from any position.
• Marine-Grade Construction: Built from aluminum and composite materials meant to resist corrosion in harsh marine and saltwater conditions for longer service life.
• Vibration Resistant: Engineered to stay locked in place at speed, offering stable viewing even during high-performance runs up to boat speeds found in the product description.
• Secure Mounting: Heavy-duty build and locking pivots reduce unwanted movement and keep displays steady while underway or when idling in chop.
• Customer Support: Manufacturer support is available for fitment questions and post-purchase assistance to resolve issues.

Who It's For

This mount suits recreational and serious anglers who own compatible Garmin, Humminbird, Lowrance or Raymarine units and need a rugged, adjustable mounting solution that resists saltwater corrosion. It is a good match for users mounting screens on consoles, side decks, or portable stations where horizontal swing and repeated angle adjustments are needed.

Those who should look elsewhere include buyers needing a tilt-only mount, extremely compact folding solutions for tight storage, or mounts explicitly rated for larger commercial displays; this model focuses on universal compatibility and horizontal swing rather than full heavy-gauge commercial duty.

Pros & Cons

Pros

• Strong construction from marine-grade aluminum and composite materials ensures corrosion resistance in salty conditions.

• Designed to remain stable at higher speeds, reducing screen vibration and movement when underway.

Cons

• Because it emphasizes horizontal swing and sturdy build, it may be bulkier than ultra-compact folding mounts for very tight storage spaces.
