Aluminum 1.5" Ball Fish Finder Mount for Hummingbird Helix 5,7, etc., C Size Universal Marine Electronics Bracket
Quick take
This 1.5” ball-and-socket fish finder mount is made for anglers who want a sturdy, highly adjustable way to position a compatible Hummingbird Helix control unit and screen. It’s built from marine-grade aluminum with stainless hardware and is designed for saltwater conditions, but it is not compatible with several newer larger Helix models (like Helix 8/9/10/12/15 and Solix 10/12/15).
Pros and cons
Pros
- Marine-grade aluminum construction with stainless steel hardware for corrosion resistance in salty environments.
- Near-infinite adjustability via a 1.5 inch (38mm) C-size ball joint and socket system.
- Drill-down mounting with a universal flat-surface base and included mounting hardware.
- Compatibility designed around 1.5” C-size adapters, including systems using standard C-size ball mounts.
Cons
- Not compatible with certain larger Hummingbird Helix and Solix models, so double-check model fit before buying.
- Some buyers report disappointment with the quality of included dash mounting screws, suggesting you may want better hardware for your installation.
What buyers think
Buyer-review evidence is largely positive on fit, stability, and day-to-day usability. Reviews frequently describe a secure feel, straightforward adjustment, and an installation experience that is easy when you are mounting it to the right compatible unit. A small amount of review feedback suggests the included screws for attaching to the dash or deck can be weaker than the rest of the mount, so your mounting outcome may depend on your surface thickness and how the fasteners hold up during tightening.
Who this mount is for
This mount is a strong match if you are trying to upgrade or replace a fish finder/GPS mount for a compatible Hummingbird setup, especially Helix 5 and Helix 7 series units. It is also a good fit for kayak, small-boat, and flat-surface installations where you want to drill down once, then freely adjust the screen position afterward.
Best for
- Helix 5 or Helix 7 owners who want a 1.5” C-size compatible ball mount system.
- Saltwater anglers who want corrosion-resistant materials (aluminum plus stainless hardware).
- People who value fine screen angle adjustment for different seated positions or changing ride angles.
You may want to skip it if
- You plan to mount a model listed as not compatible (including Helix 8/9/10/12/15, and Solix 10/12/15).
- Your installation depends heavily on the included dash screws and you prefer to use higher-quality hardware from the start.
Key features that affect real-world use
1.5” C-size ball-and-socket adjustability
The central advantage is the C-size (1.5 inch / 38mm) ball joint design, which is made for broad compatibility with standard 1.5” C-size adapters and arms. That adjustability is helpful if you share a setup between multiple users or frequently change viewing angles for glare and comfort.
Heavy-duty mounting capacity (and what it means)
The mount is rated for up to 15.5 lbs at rest and 4.5 lbs in motion. For most fish finder and chartplotter screen units, that is intended to provide stable positioning during typical boating vibration and movement.
Marine-grade materials for saltwater conditions
It uses powder-coated marine-grade aluminum along with stainless steel hardware. The design is also salt spray tested for extended resistance, and the body is cast as one piece of aluminum for strength under wave impact.
Drill-down install with included mounting hardware
The system includes a flat-surface base (with a universal hole pattern) and includes multiple sets of stainless steel machine screws, lock nuts, and sheet metal screws. You also get a double socket arm (5.5” length) as part of the kit, plus plates that work with the 1.5” ball adapter approach.
Compatibility notes (important)
This mount is designed to work with specific Hummingbird Helix units, including Helix 7, Helix 5, and multiple Helix 5 variants (DI, SI, GPS combinations, XD GPS, sonar variants). It is not compatible with certain larger Helix models and Solix 10/12/15 units. If you are upgrading from a different model family, confirm fit based on the device listed as compatible, and also confirm you have the correct 1.5” C-size ball interface for your setup.
Pros and cons summary
- Pros: corrosion-resistant build, strong adjustability, drill-down stability, and broad 1.5” C-size adapter compatibility.
- Cons: model compatibility limitations for certain Helix/Solix lines, and some reports of weaker included screws for dash attachment.
Verdict
If you have a compatible Hummingbird Helix 5 or Helix 7 control unit and you want a sturdy, saltwater-ready mount with lots of viewing-angle flexibility, this 1.5” C-size ball mount is a practical choice. The main reason to hesitate is compatibility with your exact model, plus the possibility that you will want to use better mounting hardware than the included screws for your specific deck or dash setup.
