Garmin Panoptix LiveScope™ Transducer Extension Cable - 3' - 21-Pin

The Garmin Panoptix LiveScope™ Transducer Extension Cable – 3' – 21-Pin gives anglers and boaters the extended reach needed to mount live-imaging sonar away from the helm or transom mounting point. If you've spent time on the water, you know that transducer placement directly impacts image quality and fish-finding capability; this extension cable solves the positioning challenge without requiring a second transducer. Built to Garmin's marine-grade standards, it's engineered for boats of all sizes where optimal sonar placement demands cable runs beyond the standard connection length.

This 3-foot extension uses Garmin's proprietary 21-pin connector architecture, maintaining full signal integrity and power delivery to your LiveScope transducer system. The cable construction is rated for saltwater and freshwater environments, with corrosion-resistant connectors and a flexible jacket that withstands the rigors of boat installation—routing through gunwales, along transoms, or through cabin passes without kinking or signal degradation. The compact 0.3-pound weight and manageable 6" x 2" x 8" package dimensions make it easy to stow and install, while the marine-grade shielding prevents electromagnetic interference that can corrupt live sonar imagery.

Serious anglers running Garmin Panoptix LiveScope systems—whether for bass tournaments, offshore applications, or ice fishing—benefit from this extension's ability to position the transducer independently of the display unit. It's essential for center-console boats, pontoons, and catamaran rigs where transducers mount far forward or amidships. Installation is straightforward: simply connect the 21-pin male connector to your transducer and route the cable to your Panoptix unit. Compatible with all LiveScope transducer models, this cable is a must-have accessory for maximizing sonar performance and operational flexibility on the water.
