Protect Your Fishfinder with Connector Protector™

The BerleyPro Connector Protector™ is a universal marine-grade solution to safeguard plugs and connectors on the rear of your fish finder from water ingress and debris, preventing corrosion and unit failure. Crafted from durable silicon, Connector Protectors slide over your plugs, folding snugly to create a barrier around the cables and then pressed against the unit’s rear. This is designed to sit against the rear of the unit to provide a shield against water but also allow water to drain from the bottom and breathe. This straightforward addition provides peace of mind, preventing corrosion and potential damage. Keep your cables and graphs free from costly repairs or replacements with this simple yet effective protective measure. The Connector Protector™ is designed for easy application, ensuring your marine electronics remain in optimal condition, ready for your next adventure on the water.

When not in use the built-in seal cap protects your connector from dust, spray, and water. The precision internal seal creates a tight barrier against moisture, even in harsh marine conditions. Ideal for kayaks, tinnies, jetskis, and any boat where electronics are exposed. Whether you’re in calm waters or rough conditions, the Connector Protector™ keeps your connections clean, dry and working optimally.

Fits Every Setup - One Size Fits All

Designed to fit Lowrance, Garmin, Humminbird, Simrad, Furuno, Raymarine, and most other fish finder brands, Connector Protectors are simple to install, accommodating multiple plug types and cable sizes, from Ethernet and transducer cables to power leads.

On compact fishfinder units where two connectors sit within 15 mm of each other, a single oversized protector can seal both ports simultaneously. This cluster installation simplifies protection on space-constrained rear panels.
