Imagine gliding over hidden reefs or scouting prime fishing spots without missing a single detail. The Garmin GT34UHD-THP thru-hull transducer pair transforms your Garmin chartplotter into a powerful sonar system, delivering Ultra High-Definition ClearVü and SideVü images that reveal fish, structure, and bottom contours with unprecedented sharpness. Unlike traditional sonar that leaves you guessing, this pair's high-frequency arrays cut through the water to provide pinpoint accuracy, helping serious anglers and boaters make smarter decisions on the water.
Designed for thru-hull mounting, these transducers excel in boats with deadrise angles from 0 to 25 degrees, ensuring reliable performance across a wide range of hull designs. Whether you're chasing trophy fish in shallow bays or exploring deeper wrecks offshore, the GT34UHD-THP pair gives you the edge by combining downward and side-scanning capabilities in one seamless setup.
In practical use, the GT34UHD-THP shines during structure fishing. ClearVü mode excels at identifying individual fish near the bottom, distinguishing between rockpiles and weed beds that traditional 2D sonar blurs together. SideVü extends your search horizontally, spotting schools along ledges before you even motor over—saving fuel and time while increasing hookups.
For tournament pros or weekend warriors, the high CHIRP frequencies mean less noise and more detail than lower-end scanners. Pair it with your Garmin ecosystem, and you'll gain scrolling sonar history to review missed opportunities. It's particularly valuable in freshwater reservoirs or saltwater inlets where visibility is key to success.
Pro tip: Mount these at the optimal fore-aft position to minimize interference from props or keels, maximizing coverage without blind spots.

Installing the GT34UHD-THP pair requires precision for peak performance. Select hull locations forward of the prop and away from strakes to avoid turbulence. Use a fairing block for angled hulls to keep the transducers perpendicular to the waterline, ensuring bubble-free scans. Drill carefully, seal with marine-grade compounds, and route cables through existing conduits to protect against chafe. Test in shallow water post-install to verify clear images before heading offshore.
Its high CHIRP frequencies and narrow beamwidths deliver sharper, more detailed images than standard sonar, revealing finer details like fish size and structure texture at greater ranges.
Yes, the thru-hull design maintains stable contact with water at planing speeds, providing consistent SideVü and ClearVü scans without cavitation issues when mounted correctly.
SideVü scans horizontally up to 125 feet per side, spotting fish along banks, points, or wrecks before your boat arrives, allowing precise positioning.
It's optimized for deadrise angles 0-25 degrees, fitting most planing hulls like bass boats, center consoles, and offshore cruisers.
Yes, both transducers provide accurate water temperature readings alongside depth, aiding in locating thermal breaks.
Performance scales with depth; SideVü reaches full 250-foot spans at 30 feet deep, ideal for bays and rivers.

GT34UHD-THP Ultra HD Thru-Hull Transducer - Pair
Ultra High-Definition Sonar System Thru-hull Transducer
Add stunningly clear Ultra High-Definition ClearVü and Ultra High-Definition SideVü scanning sonar images to your compatible chartplotter via the GCV™ 20 sonar module. It includes 3 arrays, including a downward-facing element element — with frequencies ranging from 0.8 MHz (800 kHz) to 1.2 MHz (1,200 kHz) — and it’s recommended for hulls with up to a 5-degree deadrise angle.
Ultra High-Definition ClearVü Scanning
This mode provides brilliant image clarity of structure and fish below your boat at greater depths than other high-frequency scanning sonars by putting more power on targets via a downward-facing element.
Ultra High-Definition SideVü Scanning
This mode delivers stunningly clear images of structure and fish off to the sides of your boat. This makes it easy to scout a fishing area quickly, because you can see everything the first time with such amazing clarity.
