Extending the reach of your StructureScan 3D transducers just got simpler and more reliable. This dual 10-foot extension cable set, equipped with 12-pin connectors, gives you the flexibility to position your side- and down-imaging sonar modules exactly where they perform best—without signal loss or added noise. Ideal for larger boats or custom installations where stock cables fall short, these black cables blend seamlessly into your setup while delivering the crisp, detailed underwater views Lowrance anglers demand.

Why Extend Your StructureScan 3D Transducers?

Stock transducer cables often limit mounting options, forcing compromises on transducer placement. Poor positioning leads to shadowed scans, reduced resolution, or interference from hull vibrations. With these 10-foot extensions—sold as a matched pair—you can route transducers to optimal spots like amidships or transom edges. This setup maximizes StructureScan 3D's 455/800 kHz imaging, revealing fish-holding structures, bait balls, and bottom contours with unmatched clarity, even in murky water.

Built for Marine Demands

• Precision Engineering: 12-pin design ensures secure, waterproof connections that maintain sonar signal integrity over the full 10-foot length.
• Dual Cable Pair: Perfect for left/right transducer installs, keeping your port and starboard scans synchronized.
• Rugged Construction: UV-resistant jacket and flexible shielding withstand saltwater exposure, engine vibrations, and repeated coiling—proven tough in real-world fishing conditions.
• Plug-and-Play Simplicity: No soldering or adapters needed; just connect between your HDS or Elite units and transducers for instant extended range.

Installation Insights for Peak Performance

Start by powering down your electronics. Disconnect the transducers from the head unit, attach the extensions inline, and secure with zip ties away from power lines to minimize interference. For transom mounts, route cables through existing conduits; on stepped hulls, tuck them under gunwales for a clean look. Test in shallow water first—adjust gain and range to fine-tune StructureScan 3D's 180-degree side views. Pro tip: Pair with a thru-hull mount for speeds over 20 knots to cut drag and boost high-speed imaging.

Enhance Your On-Water Advantage

Anglers using these extensions report spotting wrecks and drop-offs twice as far, turning tough bites into limits. Boaters appreciate the clutter-free helm, with cables out of foot traffic. Backed by Lowrance's commitment to sonar evolution, this accessory future-proofs your rig for next-gen modules. Keep connections dry and inspect annually for nicks—durability meets reliability here.
