Garmin GT56UHD-THP Thru-Hull Mount Transducer - Pair — Product description

Upgrade your boat's sonar capabilities with the Garmin GT56UHD-THP thru-hull mount transducer pair, designed for anglers who demand crystal-clear views beneath and around their vessel. This powerhouse duo combines ultra high-definition scanning sonars with traditional CHIRP technology, delivering unmatched detail on fish, structure, and bottom contours—even in challenging conditions. Whether you're chasing trophy bass in shallow bays or probing deep offshore waters, these transducers help you locate and target fish more effectively, turning every outing into a potential record-breaker.

Unlock Superior Underwater Visibility

Imagine spotting a school of fish hugging a submerged tree line from over 800 inches below your hull, or scanning wide swaths to the sides for hidden wrecks teeming with snapper. The GT56UHD-THP excels here, pushing boundaries with its downward-facing element that concentrates power for deeper penetration than typical high-frequency units. SideVü scanning now reaches 20% farther at 1,000 kHz, revealing targets you might otherwise miss. High-contrast color palettes make it simple to differentiate baitfish from predators, even on bright sunny days when glare is an issue.

Powerful Sonar Frequencies for Every Scenario

Versatility is key on the water, and this transducer pair covers it all. The high-wide CHIRP traditional sonar (150-240 kHz) provides exceptional target separation for tracking individual fish in the water column. Pair it with Ultra High-Definition ClearVü at 455/800/1,000 kHz for photo-like images straight down, ideal for pinpointing drop-offs and ledges. No more guesswork—multiple frequencies adapt to shallow flats, mid-depth reefs, or deep blue water, ensuring you're always dialed in.

Key Technical Specs

  • Mounting: Thru-hull for stable, hull-penetrating performance
  • Power Output: 350 watts (traditional), 500 watts (ClearVü/SideVü)
  • Beam Coverage: Optimized for 0-70° deadrise angles
  • Cable: 25 feet for flexible routing
  • Connections: 12-pin plug-and-play with compatible Garmin units

Seamless Integration and Real-World Performance

Engineered for thru-hull installations on fiberglass, aluminum, or wood hulls, these transducers minimize air pockets and turbulence for consistent readings at all speeds. Anglers report fewer dropouts during high-speed trolling compared to transom mounts, making them a favorite for tournament pros. Pair them with Garmin chartplotters for Quickdraw Contours mapping, and you'll build custom lake charts on the fly. Maintenance is straightforward—regular hull cleaning prevents marine growth from dulling signals, keeping performance sharp season after season.

Tailored for Serious Anglers

From inshore redfish hunts to bluewater tuna runs, the GT56UHD-THP shines where precision matters. Its rugged build withstands rough seas, and the dual-unit setup allows port/starboard coverage for comprehensive side-scanning. Users love how it reveals thermoclines and bait balls invisible to lesser systems, boosting hook-up ratios. If you're tired of fuzzy sonar screens and false readings, this is the upgrade that delivers confidence on the water.

Frequently Asked Questions

What makes the GT56UHD-THP different from standard transducers?

It combines UHD ClearVü and SideVü scanning with high-wide CHIRP in one unit, offering deeper reach and sharper side imaging—up to 20% more range at 1,000 kHz—compared to basic models.

Is this transducer suitable for high-speed boating?

Yes, the thru-hull design reduces interference from prop wash and waves, providing reliable sonar data even at planing speeds.

What Garmin fishfinders work with the GT56UHD-THP?

It's compatible with most recent Garmin chartplotters and sounders featuring 12-pin transducers, like those in the GPSMAP and ECHOMAP series.

How deep can the ClearVü and SideVü scan?

ClearVü provides remarkable definition up to 800 inches below the boat, while SideVü extends coverage hundreds of feet to each side, depending on conditions.

What's the best way to install a thru-hull transducer?

Choose a flat hull section forward of the prop, fair the mount to the deadrise angle, and seal thoroughly with marine sealant to prevent leaks.

Does it come as a single unit or pair?

This is sold as a pair, perfect for dual thru-hull setups offering complete forward, downward, and side coverage.

This all-in-one transducer offers ultimate versatility, featuring Ultra High-Definition ClearVü and SideVü scanning sonars, high wide CHIRP traditional sonar and more, so you can spend more time catching fish.
