Lowrance XT-12BL 12' Extension Blue Connector

The Lowrance XT-12BL 12' Extension Blue Connector is an essential accessory for anglers and boaters who need to extend their transducer cable beyond standard reach. Whether you're running a transducer from a bow-mounted unit to an amidships or stern installation, or positioning your sensor away from engine interference and aeration, this extension cable solves real-world mounting challenges on boats of all sizes. Built to Lowrance's exacting standards, it ensures your sonar system maintains full signal integrity across the extended run.

The XT-12BL features a 12-foot length with a Blue Connector (BL) design that is fully compatible with Lowrance's BL transducer lineup, ensuring secure, weatherproof connections that won't degrade signal quality or introduce noise into your sonar display. The cable assembly is constructed with marine-grade shielding to prevent electrical interference from engines, alternators, and other onboard systems—critical for maintaining clean sonar returns in demanding saltwater and freshwater environments. At just 2 pounds, the lightweight design minimizes stress on mounting brackets and keeps your boat's weight distribution balanced.

This extension cable is ideal for anglers running split sonar systems, structure scanning setups, or installations where the transducer must be positioned away from the main display unit. Boaters working with newer Lowrance CHIRP and broadband transducers benefit from extended placement options that reduce dead zones directly beneath the boat and improve detection of suspended fish and bottom composition. Installation is straightforward—simply connect the BL end to your compatible transducer and the opposite connector to your sonar head unit. For best results, route the cable away from high-voltage wiring and use adhesive-backed clips to secure it along the hull.
