Fish Finder Ball Mount with 36in AMPS Base and 10.3in Aluminum Arm

In this review the Keuvirya fish finder ball mount system is assessed for boaters and vehicle users who need a rugged, adjustable mounting solution for GPS, chartplotters and backup camera monitors. The bottom line: this mount stands out for its heavy-duty AMPS-compatible 36in bases with 1in B-size TPU balls and a 10.3in aluminum extension arm that gives broad, repeatable positioning without flex. It is best for marine and vehicle installs where corrosion resistance and a firm connection matter; those needing a very small hole pattern or a specific Garmin Striker 4cv spacing should check measurements before buying.

Key Features

• Heavy-Duty AMPS Compatibility: 36in diameter bases with pre-drilled AMPS patterns accept a wide range of mount plates for secure device attachment.
• 1in B-Size Ball System: Two 1in TPU balls provide standardized connections compatible with many RAM-style B size components for easy swaps and upgrades.
• 10.3in Aluminum Extension Arm: The long aluminum arm gives flexible rotation and reach, allowing better sight lines and reduced glare when positioned on dash or rail.
• T-Bolt Attachment: Includes a 1in ball T-bolt that adapts to dashboard, rail track systems and backup camera monitor brackets for versatile installs.
• Marine-Grade Construction: Die-cast aluminum alloy with powder coating resists high temperatures and salt environments for reliable marine use.
• Wide Device Compatibility: Designed to work with many fish finders, GPS units and monitor types from major brands when hole spacing matches.

Who It's For

The mount is aimed at boat owners, anglers and vehicle operators who need a robust, adjustable way to position a fish finder, GPS or backup monitor. It suits people who value metal construction and repeatable ball-style joints that hold position under vibration and rough water.

It is less suitable for buyers whose device uses a nonstandard hole spacing, especially units that require a 2.24in / 5.7cm pattern such as the Garmin Striker 4cv; measure your device mounting holes before ordering to confirm fit. If you need an ultra-compact puck-style mount, look for a different low-profile solution.

Pros & Cons

Pros

• Solid build quality from die-cast aluminum with powder coating for marine durability.
• Flexible positioning from the 10.3in extension arm and dual 1in ball joints for optimal viewing angles.
• AMPS-compatible 36in base makes it easy to use existing mounting plates and RAM-style components.
• Includes a T-bolt attachment for track systems and dashboard or rail installations.

Cons

• Not compatible with devices requiring the smaller 2.24in / 5.7cm hole spacing, so fit must be confirmed before purchase.
