Garmin Transducer Adapter Cable f/P72, P79, GT15 & GT30 for echoMAP™ CHIRP

Upgrade your boating setup with the Garmin Transducer Adapter Cable, designed specifically for seamless integration of transom-mount scanning transducers like the GT30 alongside in-hull traditional transducers such as the P72, P79, or GT15. This Y-cable solves a common frustration for echoMAP CHIRP users: maintaining reliable water depth readings even when your transom transducer hits cavitation from high speeds or rough waters.

Why This Adapter Cable is a Game-Changer for Your Sonar System

Picture this: you're out on the water, scanning for fish with SideVü and ClearVü clarity from your GT30, but cavitation kills your depth data. That's where this adapter shines. By connecting both an 8-pin 2D-only in-hull transducer and a 12-pin scanning transducer to a single 12-pin port on your compatible Garmin sonar, it keeps your display consistent. No more blind spots or interrupted readings—perfect for tournament anglers or weekend warriors who demand precision.

Built tough for marine environments, this cable ensures your echoMAP CHIRP, GPSMAP, or STRIKER series continues pulling accurate depth from the protected in-hull sensor. It's not just wiring; it's reliability engineered into every connection.

Key Compatibility Details

• Works with Garmin SideVü equipped sonar units, including echoMAP CHIRP combos.
• Supports transom-mount scanners: GT30 and similar 12-pin models.
• Pairs with 8-pin in-hull transducers: Garmin GT15M-IH, GT8HW-IH, Airmar P72, P79.
• Single 12-pin output to your chartplotter—clean and simple.

Practical Benefits for Boaters and Anglers

• Uninterrupted Depth Data: In-hull transducer takes over during cavitation, keeping your screen live.
• Versatile Setup: Mix scanning tech with traditional sonar for the best of both worlds—detailed structure scans plus solid bottom tracking.
• Easy Installation: Plug-and-play design means no soldering or complex wiring; just connect and fish.
• Enhanced Fishing Confidence: Spot wrecks, bait balls, and fish with CHIRP clarity while trusting your depth in all conditions.
• Space-Saving: One port, two transducers—declutter your transom and console.

Tips for Optimal Performance

To get the most from your setup, mount the in-hull transducer in a location shielded from turbulence, like forward of the strut on planing hulls. Pair it with your GT30 positioned for maximum water flow over the transducer face. Test in various speeds to fine-tune—many users report flawless performance up to 40 knots. Regular cleaning of connections prevents corrosion, ensuring years of service.

This adapter isn't just an accessory; it's the bridge to a more robust sonar experience. Whether chasing trophy bass or offshore pelagics, it keeps you informed and in control.
