Extend the reach of your Raymarine RealVision 3D sonar system with confidence using this durable 5-meter (16-foot) transducer extension cable. Designed specifically for marine enthusiasts who demand crystal-clear underwater imaging without compromising on performance, this cable bridges the gap between your RV-series transducers and multifunction displays (MFDs). Whether you’re mounting a transom RV-100 or opting for through-hull RV-200 and RV-300 models, it delivers seamless connectivity on boats of all sizes.
Boaters know the frustration of short cables limiting transducer placement. This extension solves that by providing extra length while maintaining the high-fidelity signals essential for RealVision 3D’s photorealistic views, CHIRP fishfinding, SideVision, and DownVision capabilities. It’s a simple upgrade that unlocks flexible installations, ensuring you capture every fish, structure, and contour beneath your vessel.
Why This Extension Cable Elevates Your Boating Setup
Rugged Marine-Grade Build: Engineered to withstand saltwater corrosion, UV exposure, and constant vibration, it thrives in harsh offshore conditions where lesser cables fail.
Zero Signal Degradation: The 25-pin design preserves RealVision 3D’s advanced sonar imaging quality, so you see detailed 3D bottom topography and fish arches as sharp as ever.
Effortless Connections: Features a secure, waterproof twist-lock connector on the MFD side and a matching socket for the transducer, making swaps and extensions hassle-free.
Versatile Length: At 5 meters, it’s perfect for mid-sized boats needing just enough reach without excess cable cluttering your bilge or deck.
Proven Longevity: Backed by Raymarine’s reputation for reliability, it outlasts standard cables, reducing downtime and replacement costs over seasons of heavy use.
Perfect Fit for Your Raymarine Ecosystem
This cable integrates flawlessly with RV-100 transom-mount, RV-200 in-hull, and RV-300 through-hull transducers, pairing with popular Raymarine chartplotters like those in the Axiom and Element series. It’s ideal for anglers targeting wrecks, sportfishers scanning reefs, or cruisers mapping shallows.
Smart Installation Tips for Optimal Results
Plan your route to minimize bends and avoid heat sources for best signal integrity.
Use no more than two extensions in series to keep performance peak—great for custom dash layouts.
Secure with cable ties away from props and rudders to prevent snags.
Test connections on water post-install to verify 3D sonar rendering before your first outing.
Its sleek black sheath blends into any hull or console, keeping your setup clean and professional-looking.
Real Boaters’ Edge: Scenarios Where It Shines
Imagine repositioning your transducer farther aft for cleaner water flow on a planing hull, or extending to a through-hull mount amidships without drilling new holes. Tournament bass pros use it to fine-tune SideVision sweeps for precise lure placement, while offshore captains rely on it for DownVision clarity in murky depths. It’s not just wire—it’s the difference between spotting that trophy fish first or watching it swim away undetected.
