Universal Mounting Bracket Extended Arm for Fish Finders - Secure

In this review of the Universal Mounting Bracket, the bottom line is simple: this is a solid, flexible mounting solution for small to medium marine electronics. It is aimed at boaters, kayak anglers, and off-road enthusiasts who need a stable, adjustable arm for devices like fish finders, GPS plotters, depth sounders or CB radios. The standout reason to buy is the combination of a 1.5-in ball head base, an extended aluminum alloy double-socket arm and a universal rectangular plate that accepts a wide range of hole spacings for straightforward, dependable installation.

Key Features

• Complete mounting system: Includes a 1.5-in diameter ball head base, a metal arm and a universal rectangular plate so you get a ready-to-install kit without hunting for additional parts.
• Versatile circular base: The circular base with pre-drilled holes and an AMPS pattern allows quick direct mounting to flat surfaces on boats, kayaks or ATVs.
• Adjustable long arm: The double socket arm uses a ball-and-socket design for a secure, non-slip grip with 360 rotation and infinite positioning to dial in the best viewing angle.
• Wide device compatibility: The rectangular plate supports devices with mounting hole spacings from 2.8 to 5.5 in, fitting many popular fish finders and chartplotters.
• RAM system compatibility: Fully compatible with RAM C-size (1.5-in) ball components so it can be mixed with other modular accessories.

Who It's For

This bracket is ideal for anglers and small-boat operators who need a durable, adjustable mount for fish finders, GPS units or radios. It works well for kayak and small craft installations where space is limited but a stable viewing position is important, and for vehicle or ATV use on flat mounting surfaces.

Those who should look elsewhere include users who require permanent flush mounts hidden below deck or heavy industrial installations needing oversized load ratings; this bracket is built for consumer marine electronics and general-purpose mounting rather than heavy structural tasks.

Pros & Cons

Pros

• Strong 1.5-in TPU ball and metal arm combination provides reliable holding power and smooth angle adjustment.
• Pre-drilled circular base with AMPS pattern saves time during installation and fits many flat surfaces directly.

• Compatibility with RAM C-size components increases modularity with other accessories.

Cons

• The arm and plate are designed for marine electronics sized up to medium units; very large or unusually heavy displays may require a heavier duty mount.
