Lowrance TMC-1 20' Extension Cable For Ghost Compass

Enhance your Lowrance Ghost Trolling Motor setup with the TMC-1 20-foot extension cable, designed specifically to give you more flexibility in positioning your compass module. Whether you're dealing with a cramped bow on a bass boat or need to route wiring cleanly through a center console on a larger vessel, this cable bridges the gap without compromising signal integrity or performance.

Key Benefits for Anglers and Boaters

Imagine mounting your Ghost Compass sensor exactly where it needs to be for optimal heading accuracy—farther from the motor or electronics that might cause interference—while keeping everything connected seamlessly. This extension eliminates the hassle of short factory cables, letting you customize your install for any boat layout. It's built tough for marine environments, resisting corrosion, UV exposure, and constant submersion, so it holds up through seasons of hard fishing.

• Extended Reach: 20 feet of quality cabling provides ample length for most installations, from kayaks to center consoles.
• Plug-and-Play Design: Direct compatibility with Lowrance Ghost systems using secure, weather-sealed connectors that prevent water ingress.
• Preserves Autopilot Precision: Maintains the Ghost's renowned compass accuracy for spot-on autopilot tracking and waypoint navigation.
• Streamlined Wiring: Reduces clutter and strain on original cables, promoting a professional-grade setup that lasts.

Real-World Applications

Anglers rigging multi-species boats often face wiring challenges. On a flats skiff, route this extension under gunwales to keep the compass high and dry up front. For offshore setups, it snakes through bulkheads without kinks. Tournament pros swear by it for quick swaps between boats, ensuring their Ghost Trolling Motor's heading sensor stays perfectly calibrated no matter the deck space.

Pair it with ActiveTarget or Ghost's integrated sonar for a full ecosystem that delivers fish-holding spots straight to your chartplotter. It's not just wire—it's the difference between a frustrating retrofit and a setup that runs flawlessly from launch to weigh-in.

Pro Tips for Seamless Integration

1. Plan your route ahead: Use zip ties and conduit to secure the cable away from props and high-vibration areas.
2. Test before sealing: Power up your Ghost after connection to verify compass calibration—no drifting headings mid-day.
3. Combine with junction boxes: For even longer runs or multiple extensions, daisy-chain safely to avoid signal loss.
4. Winter storage prep: Coil loosely and store dry to extend cable life through off-seasons.

Boat owners who've upgraded report fewer heading glitches and smoother joystick control, turning potential headaches into hassle-free outings. If your Ghost install feels cramped, this extension unlocks the full potential of Lowrance's brushless trolling tech.
