Minn Kota MKR-US2-13 Universal Sonar 2 Adapter Cable Connects Humminbird ONIX Fishfinder

Enhance your fishing setup with the Minn Kota MKR-US2-13 adapter cable, designed specifically to bridge your Humminbird ONIX fishfinder and a Universal Sonar 2 transducer mounted on your trolling motor. This seamless connection puts real-time underwater intelligence right where you need it most—delivering crisp 2D sonar images and precise water temperature readings without the clutter of extra wiring.

Why Anglers Trust This Adapter for Superior Sonar Performance

Universal Sonar 2 technology stands out by combining DualBeam PLUS sonar with advanced temperature sensing, giving you a clearer picture of structure, baitfish schools, and gamefish below your boat. Mounted low on the trolling motor, the transducer captures data from the optimal angle, often revealing details that bow- or transom-mounted units miss, especially in shallow waters or around weed edges.

The MKR-US2-13 cable tackles common pain points head-on. Its shielded construction blocks electrical noise from the motor, ensuring interference-free signals. IP68-rated waterproofing means it thrives in harsh marine environments—rain, splashes, or submersion won't faze it. Metal-tipped connectors add durability and further minimize sonar disruptions, making it a reliable choice for serious tournament anglers or weekend warriors chasing walleye, bass, or crappie.

Key Features That Set It Apart

• DualBeam PLUS Compatibility: Operates at 83 kHz for wide coverage (up to 240 feet in ideal conditions) and 200 kHz for detailed narrow views—perfect for traditional 2D sonar without the complexity of side imaging.
• Water Temperature Sensing: Accurate readings help you adjust lure selection, as fish behavior shifts with even small temp changes.
• Rugged Build: Fully shielded cable with marine-grade, waterproof connectors rated IP68 for submersion up to 1.5 meters.
• Plug-and-Play Design: No soldering or custom mods required—just connect your Humminbird ONIX to the Universal Sonar 2 transducer.

Effortless Integration with Your Trolling Motor Setup

Installing the MKR-US2-13 is straightforward. Route the cable along your Minn Kota trolling motor's shaft to the transducer, then plug the other end into your ONIX unit's sonar port. This keeps your deck clean and your focus on fishing. Pro tip: Secure the cable with zip ties to avoid snags during casts or when stowing the motor, extending its lifespan through countless outings.

While it excels at 2D sonar, keep in mind it's optimized for traditional imaging. For Down Imaging or Side Imaging on certain Minn Kota motors (like those with i-Pilot Link), pair it with an external transducer such as the XTM 9 series to unlock those advanced features on compatible Helix or older series units.

Comprehensive Humminbird Compatibility Guide

This adapter shines with ONIX and select SOLIX models using the MKR-US2-13 cable length. For shorter runs, other series pair with MKR-US2-8. Here's a breakdown:

Real-World Benefits for Better Bites

Imagine drifting a jig over a reef: The low-mounted transducer spots suspended crappie slabs before your main unit does, thanks to less boat swing interference. Water temp data lets you switch from powerbait to minnows on the fly. Anglers report finding more fish-holding spots faster, turning slow days into limits. It's not just a cable—it's your edge on the water.
