Picture this: you’re out on the water, chasing that perfect fishing spot or navigating tricky shallows, but your transducer cable just isn’t long enough to reach your ideal mounting spot. That’s where the Raymarine 5-meter extension cable steps in, designed exclusively for CP470 and CP570 CHIRP sounder modules. This 11-pin cable gives you the flexibility to position your sonar transducer exactly where it performs best—whether that’s farther aft on the hull, amidships for better water flow, or even up on the console for easier access.
Crafted from tough, marine-grade materials, it withstands constant exposure to saltwater spray, UV rays, and the relentless pounding of waves. Boaters trust it because it maintains crystal-clear signal integrity, ensuring your CHIRP sonar delivers precise fish arches, detailed bottom contours, and accurate depth readings without dropouts or interference.
Engineered for Real-World Boating Demands
Seamless Signal Transmission: The 11-pin connector locks securely, preserving every bit of high-frequency CHIRP data for superior target separation and bottom discrimination.
Flexible Installation Options: At 5 meters (about 16.5 feet), it bridges the gap between tight engine bays and open deck spaces, letting you customize your setup without signal loss.
Battle-Tested Durability: Double-shielded wiring resists electromagnetic interference from motors and electronics, while the rugged black jacket shrugs off abrasion from lines, gear, and foot traffic.
Plug-and-Play Simplicity: No soldering or adapters needed—just connect and go, saving you hours on the water or in the yard.
Peace of Mind Protection: Backed by Raymarine’s commitment to reliability, it holds up season after season in harsh conditions.
Perfect Fit for CP470 and CP570 Systems
This extension cable is tailor-made for Raymarine’s CP470 and CP570 CHIRP modules, integrating flawlessly with popular chartplotters like the Axiom series, eS, or gS platforms. It’s ideal for offshore anglers needing wide-coverage scanning, wreck divers mapping structures, or cruisers tracking underwater hazards.
Quick Installation Guide
Power down your system and disconnect the existing transducer cable from the CP module.
Align the 11-pin connectors—note the keyway to prevent misalignment—and push firmly until it clicks.
Route the cable along secure paths, using zip ties or conduits to avoid chafe points near props or rudders.
Test the system: Run a sonar benchmark scan to verify clear images and no artifacts.
Seal all connections with marine silicone if exposed to heavy washdown.
Pro tip: For stepped hulls or multihull setups, this length strikes the sweet spot—long enough for versatility, short enough to minimize voltage drop or noise pickup.
Unlock Better Sonar Performance On Any Vessel
Whether upgrading a compact center console or outfitting a larger sportfisher, this cable adapts to your boat’s layout. Mount your transducer deadrise-optimized for laminar flow, and let the extension handle the distance. Anglers report sharper bait schools and bottom hardness readings, turning good trips into legendary ones.
Maintenance Essentials
Keep it performing like new: Rinse with fresh water after every saltwater outing, inspect for nicks annually, and store coiled loosely to prevent kinks. Avoid sharp bends under 4-inch radius to protect internal conductors.
