Discover Superior Sonar Imaging with the Garmin GT51M-THP Thru-Hull Transducer Pair
Imagine gliding through choppy coastal waters or venturing into deeper offshore realms, where every fish arch and hidden structure reveals itself in stunning clarity. The Garmin GT51M-THP transducer pair transforms your boat's sonar setup into a powerhouse for serious anglers. This thru-hull mounted duo combines robust traditional CHIRP sonar with high-definition ClearVü and SideVü scanning, all housed in durable stainless steel stems designed to withstand harsh marine environments.
Engineered for hull deadrises up to 25 degrees, these port and starboard transducers deliver consistent performance even in rough seas. Whether you're chasing trophy fish in murky depths or mapping submerged reefs, this setup provides the sharp target separation and detailed side/down views that give you the edge.
Key Features That Set It Apart
- Versatile CHIRP Technology: Mid-band CHIRP (80-160 kHz) for traditional sonar excels at deep-water fish tracking, while ClearVü/SideVü at 260/455 kHz paints crystal-clear images of structure and baitfish schools.
- Power and Depth Mastery: 600W traditional for up to 1,800 feet, paired with 500W per element (1,500W total) scanning sonar reaching 1,000 feet ClearVü and 750 feet SideVü.
- Built Tough for Real-World Use: Stainless steel construction resists corrosion, optimized beamwidths (24°-13° traditional, 2.0°x51° at 260 kHz and 1.4°x29° at 455 kHz) ensure wide coverage without losing detail.
- Smart Temp Sensing: Integrated fast-response temperature sensor helps track water conditions for better fishing decisions.
- Seamless 12-Pin Integration: Plug-and-play with compatible Garmin chartplotters and modules via included Y-cable.

Why Anglers Choose the GT51M-THP for Coastal and Offshore Adventures
For coastal cruisers, the wide SideVü coverage spots wrecks and drop-offs from afar, letting you position perfectly before dropping lines. Offshore, the deep-penetrating traditional CHIRP locks onto pelagics with crisp arches, while ClearVü reveals bottom contours for safe navigation. The stainless steel stems and fairing blocks minimize drag and ensure reliable readings at speed, even in following seas.
Users rave about the superior separation—bait from keepers, weeds from fish—reducing guesswork and boosting catch rates. Pair it with your Garmin display for split-screen views that make spotting structure intuitive.
Effortless Installation Tips
Mounting thru-hull transducers requires precision: select spots forward of props, away from strakes. Use the included fairing blocks to align with your hull's deadrise, ensuring the face stays perpendicular to water flow. Secure with bushings and isolation plates to prevent electrolysis. A steady hand and hull sealant go a long way—test in calm water post-install to fine-tune.

Frequently Asked Questions
What makes the Garmin GT51M-THP ideal for rough water fishing?
Its rugged stainless steel stems and optimized design handle heavy seas, delivering stable sonar returns without interference from waves or boat motion.
How deep can the SideVü scan with this transducer pair?
SideVü reaches up to 750 feet, perfect for scouting ledges and schools from a distance.
Does it work with all Garmin fishfinders?
It's compatible with select Garmin models featuring 12-pin sonar ports, like premium GPSMAP xsv series and GSD modules—check your unit's specs.
What's the difference between ClearVü and traditional CHIRP?
Traditional CHIRP shows classic fish arches for depth and location; ClearVü delivers photo-like down views of bottom structure and fish holding tight.
Can I install this on a boat with a 20-degree deadrise hull?
Yes, it supports up to 25 degrees, with fairings to match your hull angle for optimal performance.
Does it include temperature sensing?
Absolutely—a fast-response sensor monitors water temp changes to help locate thermoclines and active bait zones.
How does the Y-cable simplify setup?
It connects both port and starboard transducers to a single 12-pin port on your Garmin unit, streamlining wiring.
