GT34UHD-TH zonde — caurlaides UHD ClearVū

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

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

Through-hull transducers, such as the GT34UHD-TH, provide excellent 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 engines 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, thru-hull transducers like the GT34UHD-TH are designed to work with all hull materials. Specific instructions are provided for fiberglass (core or non-core) and metal hulls.

Although installation instructions are provided, the equipment should be installed by a qualified marine installer to ensure optimal performance and prevent any damage to the boat.

A fairing block is necessary 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 cut angle of 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 chine hulls).Parallel to the bow-stern axis of the vessel.Away from seams, frames, joints, water inlets or outlets, or anything that can create air bubbles or turbulence.In an area where it is not at risk of being struck during launching, towing, or storage.For single-propulsion boats, not in the path of the propeller. For twin propulsion, 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 can agitate water (chine logs, strakes, propellers).Acoustic: Avoid mounting the transducer behind through-hulls, 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 ingress. After drilling the hole for the bolt and the anti-rotation bolts, you must seal the exposed inner core with high-quality marine 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 on 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 surface. If the transducer is not parallel, the signal may bounce away from the transducer, resulting in less clear or incorrect sonar images.
