Aluminum 1.5" Double Ball Mount with Two AMPS Round Plates, Fish Finder/Truck/GPS Mount (WINDFRD)

What buyers think

Across the available buyer feedback, the most consistent themes are build quality and day-to-day stability. Users describe the mount as solid, versatile, and able to stay where it is set, including in longer-term use on a boat. Reviewers also highlight a spring-loaded design element as a positive for maintaining tightness when conditions get rough. Buyer-review evidence is limited in scope, but the recurring pattern points toward reliable holding power and practical adjustability rather than frequent readjustment.

What this mount is for

This is a 1.5 inch double ball mount intended for mounting larger electronics and accessories like fish finders and GPS/chartplotters. It is designed to work on a range of flat or install-ready surfaces, including vehicles, boats, carts, desks, and other setups where you can drill down and secure a pedestal base.

The “double ball” concept matters because it gives you multi-angle positioning, so you can aim the screen for glare control, comfortable viewing, and better access during operation. The included AMPS round plate support is aimed at simplifying the device-side connection when your holder uses an AMPS hole pattern.

Key features that affect real compatibility

1.5 inch / 38 mm C-size ball system

The mount uses a 1.5 inch (38 mm) / C-size ball design, intended to be compatible with industry-standard 1.5 inch / 38 mm / C-size adapters and arms. If your existing ecosystem is built around that same ball size standard, this is more likely to integrate smoothly with your current parts.

AMPS round plate connection

Two round ball bases are included, along with an AMPS round plate approach for attaching compatible device holders. If your device mount uses an AMPS round pattern, this helps reduce the guesswork when choosing arms or brackets. If your device holder uses a different pattern, you may need additional adapters.

Marine-oriented materials for harsh environments

The mount is constructed with powder-coated marine-grade aluminum and stainless steel hardware. It is designed around corrosion resistance, and the hardware and materials are intended to hold up in salty or outdoor conditions.

Pros and cons (buyer-focused verdict)

Pros for the right setup

• Strong stability for fixed positioning: Buyers describe it as solid and able to stay where it is set.
• Adjustability without constant fiddling: The ball-and-socket design supports frequent angle changes, and feedback suggests it holds tight better than some less-secure alternatives.
• Better fit for marine use: Powder-coated marine-grade aluminum and stainless steel hardware are aimed at corrosion resistance.

Potential tradeoffs

• Compatibility depends on the rest of your mount system: You still need arms, bases, and device plate parts that match the C-size 1.5 inch ecosystem and your device holder’s pattern.
• It may not solve every install by itself: If your setup requires a different plate standard or additional bracket hardware, plan for extra components.

Who should buy it

• Boat and watercraft owners mounting a fish finder or chartplotter and wanting corrosion-resistant hardware.
• Truck or vehicle users who need multi-angle adjustment but do not want the mount drifting out of position over time.
• Anyone building a mounting system around 1.5 inch (38 mm) C-size ball standards who wants a durable, adjustable base.

Who should avoid it (or double-check first)

• If your existing device holder or arm system uses a different ball size standard than 1.5 inch C-size, you may face compatibility gaps.
• If you need a complete, device-specific mount kit and do not have matching arms, bases, or plate adapters already, you may need additional parts.

How it compares to other mounting options

If you are choosing between mount styles, focus on your priorities:

• Ball-and-socket mounts vs. simpler fixed pivots: Ball-and-socket systems typically offer finer aiming control, which is useful for screen viewing angles.
• Standardized ball sizes vs. proprietary mounts: If your accessories are already built around 1.5 inch C-size, this mount is more likely to integrate cleanly. If not, you might need adapters or entirely different components.
• Marine-grade materials vs. generic alloys: For salty outdoor use, corrosion resistance becomes a primary factor, and marine-oriented aluminum plus stainless hardware is a meaningful advantage.

Setup checklist before you buy

• Confirm your screen or holder uses the AMPS-compatible round plate pattern (or ensure you have the right adapter parts).
• Verify you have compatible 1.5 inch (38 mm) / C-size ball arms or adapters for the rest of your mounting configuration.
• Plan your install surface, since this uses a drill-down mounting approach for the base on a table, cart, desk, or vehicle/boat mounting area.

FAQ

Is this mount compatible with 1.5 inch C-size ball arms?

It is designed around a 1.5 inch / 38 mm / C-size ball joint standard, which is intended to be compatible with industry-standard 1.5 inch / 38 mm / C-size adapters and arms.

Does it include AMPS plate support for device holders?

Yes. The mount includes two round ball bases and an AMPS hole pattern-based round plate approach for attaching compatible device holders.

Where can this mount be installed?

It is built for drill-down mounting on flat surfaces, including a table, cart, desk, vehicle, or boat installation area.

Will it resist corrosion for marine use?

It is made with powder-coated marine-grade aluminum and stainless steel hardware, and it is positioned for high salt corrosion resistance.

Is this a complete fish finder mount kit?

It is a mounting component (the double ball mount and plate connection). Depending on your existing parts, you may still need compatible arms, bases, or a device holder that matches the AMPS plate pattern.

Will it stay tight during rough rides?

Buyer feedback highlights spring-loaded behavior as helpful for staying tightened, particularly under rougher ride conditions, though results can still depend on your installation and the rest of your mounting setup.
