Raymarine 5 in 1 5m Extension Cable

Extend the reach of your Raymarine multifunction transducer setup without compromising signal integrity or waterproof performance. The Raymarine 5-in-1 5m Extension Cable delivers reliable connectivity for boaters who demand precision in challenging marine environments. Whether you're mounting instruments farther from the transducer or rerouting cables through tight bulkheads, this extension provides the flexibility to optimize your dashboard layout for safer, more intuitive navigation.

Why Choose a Dedicated Extension for Your Raymarine System?

Generic cables often fall short in saltwater conditions, leading to corrosion, signal loss, or intermittent readings. Engineered specifically for Raymarine's 5-in-1 transducers—which bundle depth, speed, temperature, and heel/trim data into one streamlined sensor—this 5-meter extension maintains factory-spec performance. It plugs directly into the transducer head without soldering or adapters, preserving your warranty and ensuring plug-and-play simplicity.

Boaters report fewer false alarms and sharper data during rough seas, thanks to the cable's shielded construction that resists electromagnetic interference from engines and radios. Imagine repositioning your depth sounder display to the helm's sweet spot, all while keeping wiring hidden and protected.

Key Features That Stand Out on the Water

• Precise 5-Meter Length: Extends total run to 8 meters, ideal for mid-sized vessels without excess slack that invites wear.
• Marine-Grade Durability: UV-resistant jacket and waterproof connectors withstand constant submersion, abrasion, and temperature swings from -25°C to 70°C.
• Multi-Signal Integrity: Supports all five channels (depth, speed through water, water temperature, heel, and trim) with minimal attenuation for accurate NMEA 0183 or SeaTalk integration.
• Strain Relief Design: Reinforced ends prevent kinking during installation or flexing in heavy swells.

Streamlined Installation Tips for Peak Performance

Start by powering down your system and disconnecting the transducer. Align the keyed connector—note the small notch for foolproof orientation—and secure with the twist-lock mechanism. Route the cable along existing loom paths, using zip ties every 30cm to avoid chafe points near rudders or props. For through-hull setups, apply marine sealant around entry glands to block moisture ingress.

Test continuity with a multimeter across each pin before finalizing. Pro tip: In high-vibration areas like sailboats, add foam padding under cable runs to dampen resonance that could loosen connections over time. Most installs take under an hour, freeing you to focus on what matters—smooth sailing.

Real-World Benefits for Everyday Boaters

Owners of Raymarine i40, i50, and ST-series instruments praise this extension for enabling custom panels on flybridges or center consoles. It eliminates the hassle of short factory leads, reducing clutter and trip hazards below deck. Speed log accuracy improves with longer, stable runs away from hull turbulence, helping you trim sails or plane hulls efficiently. Plus, in tournaments or coastal cruises, reliable temp and depth data means spotting bait balls or shallows first.

For upgrades, it pairs seamlessly with Axiom plotters or Element series, feeding SmartSense data into your chartplotter for auto-calibrating speed-over-ground corrections.

Long-Term Maintenance for Lasting Reliability

Rinse with fresh water after every outing to flush salt crystals. Inspect connectors quarterly for corrosion—using dielectric grease sparingly on pins extends life. Avoid sharp bends (minimum radius 5cm) and store spares coiled loosely in a dry locker. With proper care, this cable outlasts seasonal replacements, saving you downtime during prime fishing windows.
