Garmin GT22HW-TM Plastic, TM or Trolling Motor Transducer, High Wide CHIRP/CHIRP DownVü - 455/800kHz, 500W, 8-Pin
Garmin GT22HW-TM Plastic, TM or Trolling Motor Transducer, High Wide CHIRP/CHIRP DownVü - 455/800kHz, 500W, 8-Pin — Product description
Upgrade your freshwater fishing setup with the Garmin GT22HW-TM transducer, a versatile powerhouse designed for transom or trolling motor mounting. This 8-pin transducer delivers exceptional CHIRP traditional sonar alongside CHIRP DownVü scanning sonar, helping you spot fish arches with razor-sharp clarity and reveal underwater structures like never before. Whether you're chasing bass in shallow bays or scanning deeper waters, its high-wide beam and precise imaging give you the edge to find and catch more fish.
Why Anglers Trust the GT22HW-TM for Superior Sonar Performance
Freshwater enthusiasts rave about this transducer's ability to cut through murky water and deliver consistent, high-definition returns. The high-wide CHIRP traditional sonar (150-240 kHz) paints a broad picture of the water column up to 800 feet, while the CHIRP DownVü elements (455/800 kHz) provide photo-like downward views down to 500 feet. Imagine distinguishing between a weed bed and a school of crappie at a glance— that's the real-world advantage this unit brings to your boat.
Its compact design shines on trolling motors, making it a favorite for kayak anglers, bass boats, and pontoons. Unlike bulkier models, it mounts cleanly without drag, ensuring smooth operation even at higher speeds. Paired with Garmin's ecosystem, it unlocks advanced features like split-screen views on compatible chartplotters, turning raw data into actionable fishing intelligence.
Key Features That Set It Apart
- Beam Flexibility: Traditional sonar offers 24°/16° coverage for wide-area scanning; DownVü beams (2.0°x50° at 455 kHz and 1.0°x30° at 800 kHz) deliver pinpoint detail straight below your hull.
- Power and Depth: 250W RMS for traditional CHIRP ensures reliable performance in varied conditions; 500W for DownVü handles tougher environments with ease.
- Versatile Mounting: Supports transom angles from 0° to 70°, with included hardware for quick setup on outboards, stern drives, or trolling motors.
- Durable Build: Rugged plastic housing withstands splashes, sunlight, and constant submersion, built for seasons of heavy use.
- Long Reach: 20-foot cable provides ample length for clean routing to your display unit.
Experience fewer false readings and more hookups—users often report spotting fish holding tight to structure that traditional 2D sonar misses entirely.

Effortless Installation Tips for Peak Performance
Mounting is straightforward with the included transom and trolling motor hardware. Position the transducer parallel to the waterline at rest for optimal beam projection—about 1/8 inch below the hull. Secure cables away from interference sources like engines or bilge pumps to minimize noise. Test in shallow water first to fine-tune angle and verify clear bottom tracking. Pro tip: On trolling motors, align it dead center for balanced imaging during turns.

Frequently Asked Questions
Is the Garmin GT22HW-TM compatible with all Garmin fishfinders?
It works with most Garmin chartplotters and fishfinders featuring 8-pin sonar ports, such as echoMAP, STRIKER, and GPSMAP series. Always verify your model's specs for CHIRP and DownVü support.
Can I use this transducer on saltwater?
While optimized for freshwater, its durable housing handles light saltwater exposure. For heavy marine use, consider Garmin's saltwater-rated models.
What's the difference between CHIRP traditional and DownVü?
Traditional CHIRP scans a cone-shaped area ahead and below for fish arches and depth. DownVü shoots narrow beams straight down for high-res imaging of bottom contours, fish, and bait.
How do I mount it on a trolling motor?
Use the included trolling motor mount bracket. Clamp it securely to the lower unit, ensuring the face points straight down. Adjust for hull deadrise if needed.
Does it measure water temperature?
Yes, it includes a temperature sensor for real-time surface water readings, perfect for tracking thermoclines.
What if I need deeper scanning capability?
Up to 800 feet traditional depth suits most freshwater lakes. For oceans or extreme depths, pair with a higher-power Garmin transducer.
Is wiring extensions available?
Garmin offers extension cables up to 50 feet. Solder connections carefully or use Garmin adapters to maintain signal integrity.
Equip your rig with the GT22HW-TM and transform how you read the water—clearer targets mean more fish in the livewell.
