GT34UHD-TM zonde — UHD ClearVū aizmugures ekrāns

The Garmin GT34UHD-TM transducer is a transom-mounted fishfinder designed to provide Ultra High-Definition ClearVü and SideVü sonar imaging. It enables detailed detection of underwater structures and fish. Its main features include:

ClearVü frequencies: 800 kHz (CHIRP range 760-880 kHz)SideVü frequencies: 1200 kHz (CHIRP range 1060-1170 kHz)Transmit power: 500 W RMSCable: 6.1 m (20 ft) with 12-pin connector

In ClearVü mode, the Garmin GT34UHD-TM transducer can reach a maximum depth of 61 meters (200 feet).

The SideVü mode of the Garmin GT34UHD-TM transducer provides a side range of 38 meters (125 feet) on each side, for a total range of 76 meters (250 feet). The maximum depth for this side range is 9 meters (30 feet).

The Garmin GT34UHD-TM uses Ultra High-Definition ClearVü and SideVü sonar imaging technologies. These technologies are based on CHIRP for improved target separation and superior image clarity.

The GT34UHD-TM is a transom-mount transducer. This means it is mounted externally on the transom of the boat.

Yes, transducers with a through-hull design like the GT34UHD-TM work with any hull material. However, they are not recommended for sailboats due to excessive heel, nor for deep-V hull boats.

For optimal performance, the GT34UHD-TM transducer must be mounted on the transom, parallel to the waterline and as close as possible to the centerline of the boat. It is critical to install it away from the propeller and any source of turbulence (strake, strut, fittings, water intake or discharge openings) that could create air bubbles and interfere with the sonar signal.

To avoid interference from the propeller wash, mount the transducer at least 38 cm (15 inches) from the propeller. If your propeller rotates clockwise, mount the transducer on the starboard (right) side. If it rotates counterclockwise, mount it on the port (left) side.

To install the GT34UHD-TM transducer, you will need the following tools:

A drill and drill bitsA Phillips screwdriver size #2Masking tapeMarine sealant

To protect the transducer and mounting hardware from marine growth, you must coat them with a water-based antifouling paint. Before applying, lightly sand the transducer and hardware with a fine-grit abrasive pad, then wipe them down with isopropyl alcohol. Never use acetone or acetone-based products, as this will damage the transducer's plastic housing.

The depth sounder comes with a 6.1-metre (20-foot) cable. If you need to route the cable through the transom, use a 25 mm (1 inch) drill bit to bore a cable pass-through hole for 8- or 12-pin cables. Ensure the hole is drilled well above the waterline and seal it thoroughly around the cable with marine sealant.

To reduce electromagnetic interference, ensure proper grounding of the sonar unit and other equipment. You can also install a ferrite bead on the transducer cable, route the cable away from other powered cables, or if the cable must cross a power cable, orient them at 90 degrees. Applying EMI tape can also help isolate the cables.

Yes, the beam angle of the depth sounder may need adjustment. If results are unsatisfactory, a slight angle modification can strengthen the signal and improve sonar images. The transducer must be parallel to the water surface to prevent the sonar signal from bouncing far from the transducer.

If the sonar signal is lost or significantly degraded at a certain speed, note that speed. Return to that speed and perform moderate turns in both directions. If the signal strength improves while turning, this indicates the transducer is not sufficiently submerged or is in a turbulent area. You will need to adjust the transducer depth by lowering it by about 3 mm (1/8 inch) at a time.

No, cutting the depth sounder cables is strongly discouraged as it will void the product warranty.

The Garmin GT34UHD-TM transducer is compatible with Garmin chartplotters featuring a 12-pin connector and supporting Ultra High-Definition ClearVü and SideVü sonar technologies. It is recommended to verify specific compatibility with your Garmin chartplotter model.

Yes, it is imperative to update the software of your Garmin chartplotter when installing this depth sounder to ensure optimal performance and full compatibility. You can do this via the ActiveCaptain app if your chartplotter has Wi-Fi, or via an SD card with a Windows or Mac computer.

Yes, you can use multiple transducers. However, if you use two transducers of the same frequency simultaneously, they may interfere with each other. It is recommended to mount them at least 60 cm (24 inches) apart. You can operate two transducers of different frequencies simultaneously without interference issues.

To maintain the warranty of your Garmin GT34UHD-TM depth sounder, it is crucial not to cut the transducer cables, as this will void the warranty. Installation and maintenance must be carried out in accordance with Garmin's provided instructions to avoid any damage or injury.
