Humminbird Dual HELIX® Starter Kit HWAL - Transom Product Description

Simplify Your Fishing Setup with the Dual HELIX Starter Kit for Aluminum Boats

Setting up advanced sonar on an aluminum boat can be tricky due to thin hulls and unique mounting challenges, but this starter kit changes the game. Designed specifically for transom installations on aluminum vessels, it lets you network two Ethernet-capable HELIX fish finders effortlessly. You'll get crystal-clear Dual Spectrum CHIRP sonar from the included transom transducer, seamless integration with your existing Side and Down Imaging setup, and even compatibility with select Minn Kota trolling motors featuring built-in MEGA Imaging. Anglers love how it cuts through setup hassles, delivering pro-level performance right from the water.

What's Included in Your Kit

  • XNT 9 HW T transom-mount Dual Spectrum CHIRP transducer for reliable 2D sonar coverage
  • AS EC 20E 20-foot Ethernet cable for stable networking between units
  • Two AS EC QDE Ethernet adapters for quick connections
  • MKR-MI-1 adapter to link compatible HELIX units to Minn Kota motors with MEGA Imaging
  • 9 M SIDB Y transducer splitter cable to combine Dual Spectrum CHIRP with Side/Down Imaging

This all-in-one bundle ensures you have every cable and adapter needed, eliminating guesswork and extra trips to the store.

Perfect Match for Top HELIX Models

Built to work flawlessly with popular HELIX series graphing units, including HELIX 8 G3N/G4N, HELIX 9 G2N/G3N/G4N, HELIX 10 G2N/G3N/G4N, HELIX 12 G2N/G3N/G4N, and HELIX 15 G4N. Networking two units means sharing real-time sonar data, waypoints, and charts across your dash—ideal for tournament fishing or guiding clients without missing a beat.

Standout Features That Boost Your On-Water Edge

  • Effortless Dual Transducer Setup: The splitter cable merges your new CHIRP transducer with existing Side/Down Imaging for comprehensive coverage—spot baitfish schools and bottom structure simultaneously.
  • Minn Kota Integration: Plug into motors with built-in MEGA Imaging for forward-facing sonar without drilling extra holes.
  • Rugged Marine Build: Handles rough waters, splashes, and vibrations on aluminum hulls that flex under power.
  • Quick Networking: Ethernet backbone shares sonar between HELIX units faster than wireless options, with zero lag.

Aluminum boats often vibrate more and have interference-prone hulls, but this kit's transom-focused design minimizes noise and maximizes signal quality for sharper images at all depths.

Step-by-Step Installation Tips for Aluminum Boats

Installing on an aluminum transom is straightforward with these pro tips:

  1. Clean the transom thoroughly and select a spot 1/3 back from the stern, away from strakes or prop wash.
  2. Mount the XNT 9 HW T transducer parallel to the waterline using stainless hardware to resist corrosion.
  3. Route cables through existing gunnels or add protective conduit to shield from snags.
  4. Connect the Ethernet cable between HELIX units and power up—auto-discovery handles the rest.
  5. Use the splitter to blend signals; calibrate in shallow water for peak performance.

Pro Tip: Test in a barrel before launch to fine-tune gain and avoid on-water surprises. This kit's plugs-and-play cables reduce wiring time by half compared to piecemeal setups.

Unlock Better Catches with Advanced Sonar Networking

Imagine running dual HELIX screens: one zoomed on structure with Side Imaging, the other tracking fish with Dual Spectrum CHIRP—all synced. On aluminum boats, where space is tight and hull slap creates clutter, this kit delivers cleaner returns and deeper insights. Pair it with Minn Kota's MEGA Live for real-time jig-tracking, and you'll locate hotspots others miss. Seasoned walleye hunters and bass pros swear by networked setups for covering more water efficiently.

Care and Maintenance for Longevity

  • Rinse with fresh water after saltwater use.
  • Check cable connections seasonally for wear.
  • Store transducers padded to prevent dings.

Frequently Asked Questions

What makes this kit ideal for aluminum boats?

Aluminum hulls are thinner and more prone to vibration, which can interfere with sonar. This transom kit includes components optimized for HWAL (Humminbird Wide Aluminum) setups, ensuring stable mounting and minimal noise for reliable readings.

Can I use this with my existing Side Imaging transducer?

Yes, the included 9 M SIDB Y splitter cable connects the new Dual Spectrum CHIRP transducer directly to your Side/Down Imaging setup, giving you both on one HELIX display.

Does it work with Minn Kota trolling motors?

Absolutely—the MKR-MI-1 adapter links compatible HELIX 8-15 MEGA Imaging units to select Minn Kota motors with built-in MEGA Imaging for trolling motor-mounted sonar.

Which HELIX models are compatible?

It's designed for Ethernet-equipped HELIX 8 G3N/G4N, 9 G2N/G3N/G4N, 10 G2N/G3N/G4N, 12 G2N/G3N/G4N, and 15 G4N series units.

How do I network two HELIX units with this kit?

Use the 20-foot AS EC 20E Ethernet cable and QDE adapters to connect the units directly. Power on, and they'll auto-share sonar, GPS, and charts via Ethernet.

Is installation DIY-friendly?

Yes, most users complete it in under an hour. Follow transom mounting best practices, route cables securely, and test in calm water for optimal results.
