Sonda GT34UHD-TH - probušna UHD ClearVü

The Garmin GT34UHD-TH is a through-hull transducer designed for demanding recreational boaters. It provides ClearVü and SideVü scanning capabilities in Ultra High Definition, delivering highly detailed images of structure and fish beneath and beside the vessel.

The GT34UHD-TH transducer uses ClearVü Ultra High Definition and SideVü Ultra High Definition sonar technologies. These CHIRP modes provide enhanced image clarity for precise detection below and alongside your boat.

In ClearVü Ultra High Definition mode, the Garmin GT34UHD-TH fishfinder offers a maximum detection depth of 200 feet (approximately 61 meters).

The ClearVü Ultra High Definition mode of the GT34UHD-TH fishfinder operates within a CHIRP range of 760–880 kHz, with a nominal frequency of 800 kHz.

For SideVü Ultra High Definition scanning, the Garmin GT34UHD-TH transducer operates on a CHIRP range of 1060–1170 kHz, with a nominal frequency of 1200 kHz.

The Garmin GT34UHD-TH fishfinder has a transmission power of 500 W in ClearVü Ultra High Definition mode.

The Garmin GT34UHD-TH is a thru-hull transducer, meaning it installs through a hole in your boat's hull.

Through-hull transducers, such as the GT34UHD-TH, provide superior overall signal quality, even at higher speeds and greater depths. They are less sensitive to turbulence generated by the hull than transom-mount models and work with all types of motors and hull materials.

The Garmin GT34UHD-TH transducer integrates directly with Garmin displays from the 8600xsv and ECHOMAP Ultra series.

Yes, for other compatible Garmin devices, the GT34UHD-TH transducer can be used via the Garmin GCV™ 20 sounder module.

Yes, through-hull transducers such as the GT34UHD-TH are designed to work with all hull materials. Specific instructions are provided for fiberglass (cored or non-cored) and metal hulls.

Although installation instructions are provided, it is strongly recommended that the equipment be installed by a qualified marine installer to ensure optimal performance and avoid any damage to the boat.

A fairing block is required if the deadrise angle of the mounting location exceeds 5°. The fairing block ensures the transducer is positioned parallel to the waterline for improved sonar accuracy. The maximum cutting angle for the fairing block is 25°.

The ideal location must be:

In front of and near the engine (for outboards and inboards).In front of the first chine (for vee-bottom hulls).Parallel to the bow-stern axis of the vessel.Away from seams, frames, fittings, water intakes or outlets, or anything that may create air bubbles or turbulence.In an area where it cannot be struck during launching, towing or storage.For single-screw boats, not in the propeller wash. For twin-screw boats, between the propellers if possible.It is important to ensure the transducer is in clean, non-turbulent water for optimal performance.

To reduce interference:

Electromagnetic (EMI): Ensure proper grounding, install a ferrite bead on the transducer cable, route the cable away from other powered cables, or cross cables at 90 degrees if necessary.
Turbulence: Mount the transducer as far as possible from equipment or hull features that may agitate the water (keel lines, strakes, propellers).
Acoustic: Avoid mounting the transducer behind through-hull fittings, water inlets or outlets, or hull irregularities. If using multiple transducers, space them at least 60 cm (24 in) apart.

Yes, for a fiberglass hull with a core, the core must be carefully cut and sealed to prevent water intrusion. After drilling the hole for the rod and anti-rotation bolts, you must seal the exposed inner core with marine-grade epoxy resin and allow it to cure before attaching the transducer. It is also important not to overtighten the nuts to avoid damaging the hull.

Yes, it is mandatory to update the software of your Garmin display when installing this transducer to ensure compatibility and optimal performance.

The transducer must be mounted parallel to the fore-aft axis of your vessel. The transducer's beam angle must be parallel to the water's surface. If the transducer is not parallel, the signal can bounce away from the transducer, resulting in less clear or incorrect sonar images.
