Aluminum Fish Finder Lock 2 Pack, Oval Fishing Graph Security Hardware for Gimbal Mount, Anti-Theft Marine GPS Unit Protection Compatible with Garmin, Lowrance, Humminbird (Black)
Quick take
This NUOVEPE fish finder lock set is meant to secure your marine electronics more firmly than basic factory hardware, especially during storage, transport, or quick stops on the water. It’s built around an anodized aluminum housing with stainless steel hardware, but install success depends on your specific unit and mount hole sizes, since some buyers report missing or unclear installation guidance.
Pros and cons
Pros
- Corrosion-resistant materials, anodized aluminum housing with stainless steel hardware for marine use.
- Includes a 2-pack so you can protect more than one unit or setup.
- Designed for anti-theft and a stable, vibration-resistant mount feel.
- Installation uses included stainless-steel screws, with no major modification described.
Cons
- Buyer-installation support is limited, and some shoppers say instructions or dimensions are hard to find.
- Compatibility can be sensitive to your exact Garmin model and the drilled hole dimensions.
What buyers think
Buyer-review evidence is limited but points to a consistent theme: the locks generally do what they’re intended to do, providing a secure feel once tightened. Several reviews describe the hardware as working well and being sturdy, with at least one noting the install is only “somewhat easy” mainly because clearer instructions would help. There is also at least one compatibility caution involving the included anti-rotation roll pin size for a particular Garmin model, where the supplied pin did not match the hole dimensions, requiring sourcing a different size. Overall, the pattern suggests the locking concept is effective, but setup quality depends on matching your exact unit and mount hardware tolerances.
What this lock set is for
If you’ve ever left your fish finder setup exposed while loading gear, docked briefly, or transported your boat or kayak, you already know how quickly “easy to remove” mounting hardware becomes a weak point. This 2-pack focuses on replacing less-secure factory-style parts with a more rigid metal lock and stainless-steel fasteners, aiming to deter unauthorized removal and reduce shifting under vibration.
Materials and build quality
The lock housing uses corrosion-resistant anodized aluminum alloy, paired with stainless steel hardware. That combination is relevant for saltwater exposure, direct sun, and repeated day-to-day use on the water. In plain terms, it’s built to handle the typical abuse marine electronics see, rather than relying on plastic knobs or hardware that can loosen or wear over time.
Compatibility: Garmin, Lowrance, and Humminbird mounting fit
These locks are designed for common fish finder mounting setups from Garmin, Lowrance, and Humminbird. The key buying factor is whether your unit’s gimbal mount and drilled hole dimensions match the lock’s provided hardware. The review evidence includes at least one report where the anti-rotation roll pin was too small and too short for the hole size on a specific Garmin model, requiring a separate replacement part. If you’re upgrading hardware on a particular model, it’s worth measuring and confirming the mount hole requirements before you commit.
Installation experience
Installation is described as straightforward: align the lock with the mount, tighten the screws using the included stainless-steel hardware, and secure the unit. However, buyer feedback suggests documentation and exact dimensions may not be as clear as some shoppers expect. If you prefer fully guided instructions or you’re working with tight tolerances, plan on taking careful measurements, especially for any anti-rotation components.
Pros and cons in context
Who it’s best for
- Boat and kayak owners who want additional anti-theft security for their fish finder or marine GPS during storage and transport.
- Shoppers who value metal, corrosion-resistant materials over plastic-style hardware.
- Buyers who are comfortable verifying fit by checking mount hole sizes and hardware compatibility for their exact unit.
Who should avoid it (or double-check first)
- People who need highly detailed step-by-step instructions or published dimensions, and don’t want to measure parts themselves.
- Anyone installing on a specific model where prior reports suggest mismatched anti-rotation pin dimensions, unless they verify the roll pin size and hole tolerances first.
Is it worth it?
If your main goal is improving anti-theft security and stability for a compatible marine unit using a more corrosion-resistant metal lock, this 2-pack is the right category of accessory. The biggest reason it may not feel “worth it” is buyer-fit: correct compatibility with your exact Garmin, Lowrance, or Humminbird mounting and hole dimensions. With that in mind, it’s a strong value proposition for shoppers who can confirm hardware fit before install.

FAQ
Will this work with my specific Garmin, Lowrance, or Humminbird model?
It’s designed for compatibility with major brands including Garmin, Lowrance, and Humminbird, but exact mounting fit depends on your unit’s gimbal mount hole dimensions and the lock hardware tolerances. If you’re installing on a specific model, measure and confirm the hole size and the anti-rotation hardware requirements before tightening everything down.
What’s included in the 2-pack?
The set includes two locks and the accompanying hardware components, including keys, stainless-steel screws, an anodized aluminum housing, and zinc-plated lock hardware.
Is installation difficult?
Installation is intended to be simple, using alignment and tightening the included screws. That said, some buyers report that clearer installation instructions or dimensions would help, so expect to do careful fitting if you’re unsure about hardware size or drill tolerances.
Does the lock help with vibration and shifting?
It’s built to provide a more stable, secure hold intended to resist loosening and shifting under vibration, which is especially relevant during rough water or transport.
Is this lock set durable enough for saltwater?
It uses corrosion-resistant anodized aluminum and stainless steel hardware, materials that are typically suited to marine environments where salt spray and moisture are part of everyday use.
Where is the best use case for this lock set?
It’s best for securing fish finder or marine GPS units on boats and kayaks during loading, quick stops, storage, and transport, when you want stronger security and less chance of loosening than basic hardware.
