Protect Your Fishfinder with Connector Protector
The Connector Protector is your solution to safeguard plugs and connectors on the rear of your fish finders from water ingress and debris often leading to 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.

Frequently Asked Questions
What level of waterproofing does the Connector Protector provide?
The precision compression seal is engineered to offering dust-tight and continuous submersion protection. Once installed, you can immerse the connector in water without moisture ingress compromising the seal.
Can one Connector Protector cover multiple closely-spaced connectors?
Yes. 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.

How should I maintain the seal and cover over time?
After heavy saltwater exposure, rinse the protector in fresh water and allow it to air-dry. Periodic inspection for cuts or abrasion is recommended—replace the protector if the lip profile shows any permanent deformation.
