The bottom line: this is an OEM-quality bracket built for a secure, corrosion-resistant fit and simple tilt-and-swivel adjustment, making it ideal for boaters who need reliable, stable mounting and easy viewing angle changes. Our review focuses on fit, durability and ease of installation to help decide if the GB-20 is the right replacement or upgrade for your HDS-7 or HDS-7m unit.

Key Features

Who It's For

It suits those who value a tried-and-true OEM solution and who need simple, repeatable angle adjustment while underway or when switching helm positions.

It is less appropriate for owners of different display sizes or third-party mounting setups, and anyone seeking a multi-axis modern mount with integrated cable routing or quick-release features should look at alternative mounting systems.
