Garmin 12-Pin Transducer Y-Cable Port/Starboard - 10m

Enhance your marine sonar setup with the Garmin 12-Pin Transducer Y-Cable designed specifically for port and starboard SideVü transducers. This specialized cable splits a single 12-pin connection into two, enabling seamless integration of dual thru-hull or transom-mount transducers. Ideal for boaters and anglers seeking crystal-clear side-scanning images without the interference from engine lower units or hull structures, it delivers superior underwater visibility on both sides of your vessel.

Why Choose the Garmin 12-Pin Y-Cable for Port/Starboard Setup?

Traditional single-transducer setups often suffer from shadowing, where the boat's keel or engine blocks sonar signals on one side. This Y-cable solves that by supporting a dedicated port transducer for left-SideVü imaging and a starboard transducer handling traditional CHIRP sonar, ClearVü down imaging, right-SideVü, water temperature readings, and automatic transducer identification. Stretching approximately 10 meters (32 feet), it provides ample reach for most installations, ensuring flexibility in transducer placement for optimal performance.

Whether you're navigating shallow waters, hunting structure for fish, or mapping the bottom in real-time, this cable transforms your Garmin sonar unit into a powerful dual-side scanning system. It's built tough for marine environments, with rugged construction that withstands corrosion, vibration, and constant water exposure.

Key Benefits for Boaters and Fishermen

• Eliminate Shadowing: Position transducers strategically to capture unobstructed left and right SideVü views, revealing fish, wrecks, and contours hidden from single-unit scans.
• Versatile Imaging: Starboard side delivers comprehensive data—traditional sonar, ClearVü, SideVü, temp, and ID—while port focuses on dedicated left-side detail.
• Easy Expansion: Perfect upgrade for Garmin chartplotters and fishfinders supporting 12-pin GT-series transducers.
• Long-Reach Design: 10-meter length accommodates larger vessels or complex routing through bulkheads and consoles.
• Reliable Performance: Garmin's precision engineering ensures plug-and-play compatibility and stable signal transmission.

Compatibility and Technical Specs

Engineered for GT30-THP port/starboard SideVü transducers, this Y-cable works with all 12-pin GT-series models. It connects directly to compatible Garmin sonar modules, echoMAP, STRIKER, or ECHOMAP UHD series units. Confirm your sonar's port supports 12-pin networking for the best results.

Installation Tips for Peak Performance

Installing this Y-cable is straightforward but rewarding. Route the starboard leg to your right-side transducer near the hull's waterline, angled slightly downward for best SideVü sweep. Place the port leg symmetrically on the left, ensuring at least 0.6 meters separation from the starboard unit to minimize crosstalk. Secure cables away from high-voltage lines and use zip ties or conduits for protection. After connection, run your Garmin unit's transducer wizard to auto-detect and calibrate—your screens will light up with dual-side imagery in moments.

Pro tip: For thru-hull mounts, fair the transducers to the hull's deadrise angle using Garmin's mounting kits. This reduces drag and air bubbles, sharpening your scans even at higher speeds.
