Aluminum GPS Mount with 25-17mm Adapter and 10.9in Extension - Secure

In this review of the Aluminum GPS Mount with 25-17mm Adapter, the bottom line is simple: this is a durable, adjustable mounting solution for boaters and drivers who need a closer, more ergonomic view of their Garmin GPS or phone. The review finds the mount most valuable for users who want a stronger alternative to dash or suction holders and need a reliable arm that brings the device nearer to eye level. Its 10.9in extender and 17mm rotating ball make positioning straightforward while the aluminum construction keeps the mount stable in rough conditions.

Key Features

• 10.9in Dual Rod Extension: The extended arm brings screens closer to the operator for reduced neck strain and improved visibility while navigating.
• 17mm Rotating Ball Joint: The rotating ball accepts common cradle mounts and phone holders so you can fine tune angle and orientation quickly.
• AMPS Standard Round Plate: The AMPS plate accepts tablet and marine electronics mounts, expanding compatibility to iPad style holders and radios.
• High-Strength Aluminum Alloy: The metal construction resists flex and holds heavier devices more securely than many plastic mounts.
• RAM B-Size Compatibility: Works with RAM 1in ball accessories, providing easy integration with existing B-size systems and accessories.
• Multiple Mounting Options: Can use the AMPS plate screwed into the tilt base or connect directly with the 17mm ball plus cradle for Garmin Striker 4 style units.

Who It's For

The mount is best for boaters, anglers, and drivers who use Garmin 5-7in units, Striker 4, or similar GPS/fish finder heads and want a rigid, close-in viewing position. It also suits users who already own RAM B-size accessories and want a metal upgrade to dash or beanbag mounts.

It is less appropriate for people who need a purely portable or ultra-compact solution that stows away completely, or for those whose devices require proprietary brackets not compatible with a 17mm ball or AMPS plate.

Pros & Cons

Pros

• Solid aluminum build gives dependable stability in choppy or bumpy conditions.
• Long 10.9in extender reduces neck strain by bringing the display nearer to eye level.
• Dual compatibility with 17mm ball cradles and AMPS round plates increases device options.
• Works with RAM B-size systems for easy accessory integration.

Cons

• Heavier than plastic mounts, so it requires a secure base and careful installation to avoid stress on thin dash surfaces.
• No included device-specific cradle for every model; some users will need to supply a compatible 17mm ball adapter or AMPS plate mount.
