The included GT51 transducer packs Garmin's high-wide CHIRP traditional sonar alongside ClearVü and SideVü scanning, giving you nearly photographic down and side views—perfect for spotting bait schools or drop-offs in real time.
Standout Features Tailored for Serious Boaters
- Sunlight-Readable Display: The 7-inch WVGA touchscreen shines even under harsh sunlight, with keyed controls for gloved hands or bumpy rides.
- Quickdraw Contours: Generate your own 1-foot contour maps on the fly, customizing hotspots and sharing them effortlessly with the community.
- Wi-Fi Connectivity: Pair seamlessly with the ActiveCaptain app for software updates, community insights, marina details, and smart notifications from your phone.
- Versatile Mounting: Quick-release bail mount, flush options, and compatibility with transom or trolling motor setups make installation a breeze.
- Expandability: Add Panoptix all-seeing sonar for live-action views around and below your boat, or connect NMEA 2000 devices for engine data and audio.
Revolutionary Sonar: See More Fish, Find More Structure
Garmin's CHIRP technology transforms how you fish. Traditional CHIRP sonar delivers exceptional target separation at depths up to 2,300 feet, outperforming standard sonar by focusing energy precisely where it counts. ClearVü provides down-imaging so sharp it feels like looking through glass, while SideVü scans 100+ feet to each side, highlighting wrecks, ledges, and cruising fish without leaving your spot.
All this power comes bundled in one GT51 transducer, supporting Minn Kota and MotorGuide trolling motors. Features like sonar rewind, bottom lock, and water temp graphs let you analyze past scans, ensuring no bite goes unnoticed. For black-box setups or advanced trolling, it's a game-changer that helps you dial in lures and depths faster.
Stay Connected On and Off the Water
Built-in Wi-Fi links your display to the ActiveCaptain app, unlocking community Quickdraw data, POI searches, and effortless chart swaps—no SD cards needed. NMEA 2000 compatibility integrates with autopilots, sensors, FUSION audio, and more. AIS and DSC support tracks vessels and shares positions via VHF, boosting safety in busy waters.
Quick-release design means secure storage ashore: cords stay plugged into the mount, so you're in and out in seconds.
