Lowrance TMC-1 20' Extension Cable For Ghost Compass

The Lowrance TMC-1 20' Extension Cable for Ghost Compass is an essential accessory for anglers and boaters who demand extended installation flexibility with their Lowrance marine electronics. Built to bridge the distance between your Ghost Compass heading sensor and primary display unit, this extension cable allows you to position your compass module away from electromagnetic interference or structural constraints common on modern fishing vessels and cruising boats. If your Ghost Compass needs repositioning for optimal deck layout or sensor accuracy, this purpose-built extension eliminates costly equipment reconfiguration.

Lowrance engineered the TMC-1 extension cable with marine-grade construction to withstand saltwater exposure, UV degradation, and the vibration cycles inherent to high-performance center consoles and offshore vessels. The 20-foot length provides substantial run distance for installations on larger hulls or when routing through cabin structures, gunwales, or hardtops without signal loss or voltage drop. This cable maintains the digital signal integrity required for precise compass heading data—critical for autopilot functionality, waypoint navigation, and drift-free trolling patterns that serious anglers depend on for consistent catch rates.

Boaters upgrading existing Lowrance systems or installing Ghost Compass modules on larger vessels will find the TMC-1 indispensable for avoiding sensor dead zones and reducing compass heading errors caused by close proximity to battery banks, metal rigging, or electronics stacks. Installation is straightforward—simply disconnect the compass from your display unit and insert the extension cable between them, then route to your desired mounting location. This cable is compatible with all Lowrance Ghost Compass systems and integrates seamlessly into your existing sounder, chartplotter, or integrated display ecosystem.
