Garmin ECHOMAP Plus 43cv LakeVu G3 w/GT20-TM Transducer Product Description
Discover Crystal-Clear Waters with Advanced Sonar Technology
Imagine gliding across your favorite lake at dawn, pinpointing fish and structure with stunning clarity—no guesswork involved. The Garmin ECHOMAP Plus 43cv transforms every outing into a precision adventure. Its compact 4.3-inch sunlight-readable display packs powerful CHIRP sonar and scanning capabilities into a rugged, easy-to-mount unit. Paired with detailed LakeVü g3 maps, it reveals underwater secrets that give serious anglers an edge, whether you're chasing bass in shallow coves or navigating reservoirs for walleye.
Superior Sonar for Unmatched Fishfinding
At the heart of this combo lies the GT20-TM transducer, blending Garmin's CHIRP traditional sonar with ClearVü scanning sonar. CHIRP sweeps multiple frequencies simultaneously, delivering razor-sharp target separation that traditional single-frequency sonar can't match. You'll distinguish individual fish from bait schools or weeds effortlessly, even in murky water. ClearVü adds nearly photo-like side and down views, highlighting submerged trees, drop-offs, and rocks where big catches hide.
- CHIRP traditional sonar excels in deeper water with exceptional definition
- ClearVü scanning reveals structure in vivid detail, combined in one transducer
- Supports popular trolling motors like Minn Kota and MotorGuide for seamless integration
- Maximum depth up to 2,300 feet at 77 kHz in freshwater—plenty for most lakes
Pro tip: Adjust sensitivity based on water conditions—dial it up in clear water for finer details or down in choppy waves to cut clutter.
Preloaded LakeVü g3 Maps: Navigate with Confidence
Covering over 17,000 U.S. lakes, rivers, and reservoirs, these maps integrate Navionics data for 1-foot contours that map every nuance of the bottom. Spot shallow hazards with Shading features, locate boat ramps, marinas, and hotspots effortlessly. Interstates, roads, and bridges keep you oriented on land too.
Take it further with built-in Quickdraw Contours. As you motor along, it auto-generates custom 1-foot maps of your path—your data, your secrets. Save privately or contribute to the Garmin Connect community for collective insights.
Versatile Mounting for Any Vessel
This unit shines on kayaks, bass boats, or pontoons. The quick-release tilt/swivel mount lets you snap it on or off in seconds, with cords staying plugged into the cradle for worry-free storage. Transom and trolling motor mounts included mean flexible setup without extra buys. IPX7 waterproofing shrugs off splashes and rain.
Stay Connected and Expandable
Share waypoints and routes wirelessly with compatible ECHOMAP or STRIKER units—perfect for group trips. NMEA 0183 ports link to VHF radios or heading sensors. A microSD slot supports up to 32GB for upgraded charts like LakeVü Ultra or coastal BlueChart options via the ActiveCaptain app.
