Imagine gliding silently across the water, your Minn Kota trolling motor humming along, while real-time sonar data streams directly to your Garmin fishfinder—without the hassle of mounting extra transducers. That's the game-changing convenience of the MKR-US2-1 Garmin Adapter Cable. Anglers who pair their Universal Sonar 2 (US2)-equipped Minn Kota motors with Garmin units swear by this setup for its simplicity and superior performance on the water.
Universal Sonar 2 isn't just any transducer tech; it's Minn Kota's advanced system built right into select trolling motors like Terrova, PowerDrive V2, and Riptide models. It delivers DualBeam PLUS sonar (200 kHz single beam or 200/83 kHz dual beams) for versatile coverage—wide for scouting structure and narrow for pinpointing fish—plus precise water temperature readings to dial in your lure choices based on species preferences.
This 6-pin adapter cable bridges the gap between your Minn Kota US2 transducer and Garmin fishfinder seamlessly. No more drilling holes or dealing with tangled wires. Simply plug one end into the motor's sonar port and the other into your Garmin unit. The shielded cabling and metal-tipped, IP68-rated waterproof connectors block out electrical noise from the motor, ensuring clean signals even in choppy conditions or during long outings.
Pro tip: Before heading out, route the cable along the motor shaft using zip ties to keep it secure and drag-free. This prevents wear from submersion and vibration, extending the life of your gear.
Designed specifically for legacy Garmin models that thrive with US2's reliable sonar output, this adapter supports a range of trusted fishfinders. Here's a breakdown by series:
