GT23M-TM zonde - aizmugurējais panelis CHIRP/ClearVū

The Garmin GT23M-TM is a plastic transducer designed for transom mounting. It integrates traditional mid-band CHIRP sonar and CHIRP ClearVü technology. This 8-pin model provides a versatile solution for detailed underwater detection, with depth tracking and water temperature capabilities.

The Garmin GT23M-TM fishfinder is designed specifically for inshore and offshore anglers, providing detailed underwater detection for these environments.

The traditional CHIRP sonar of the Garmin GT23M-TM sounder operates on a mid-band frequency range of 80 to 160 kHz.

The Garmin GT23M-TM transducer's traditional CHIRP sonar has a power output of 600 W.

The Garmin GT23M-TM CHIRP traditional sonar can reach a maximum depth of 549 meters (1,800 feet).

The CHIRP ClearVü sonar of the Garmin GT23M-TM transducer operates on frequencies of 260/455 kHz, specifically 245-275 kHz and 445-465 kHz.

The Garmin GT23M-TM transducer's CHIRP ClearVü sonar has a power output of 500 W.

The Garmin GT23M-TM CHIRP ClearVü sonar can reach a maximum depth of 305 meters (1,000 feet).

The beam angle of the traditional CHIRP sonar on the Garmin GT23M-TM sounder ranges from 24° to 13°.

Yes, the Garmin GT23M-TM transducer can track water temperature.

The Garmin GT23M-TM transducer cable is 9.1 meters (30 feet) long.

To install the GT23M-TM transducer, you will need the following tools:

A drill and drill bits (a 4 mm (5/32 in) bit for pilot holes and a 25 mm (1 in) bit for the 8-pin cable passage)Two 13 mm hex keysA No. 2 Phillips screwdriverMasking tapeMarine sealant

For optimal performance, the depth sounder must be mounted:

As close as possible to the centerline of the boat.In an area of clean water (non-turbulent), away from propellers, chines, stringers, fittings, water discharge outlets, or anything that could create air bubbles.At least 38 cm (15 inches) from the propeller and on the opposite side of the propeller’s rotation to avoid propeller wash.

So that the center of the bottom of the transducer is flush with the lower edge of the transom and parallel to the waterline.

To reduce interference with the sonar signal, it is recommended to:

Mount the transducer away from sources of electromagnetic interference (electronic devices, engines, radar). Avoid turbulence zones created by hull features (chine, stringers, ribs) or the propeller. Install the transducer away from sources of acoustic noise (other transducers, boat machinery, wind, waves, rain). If the transducer cable must cross a power cable, orient the cables at 90 degrees. If using multiple transducers, mount them at least 60 cm (24 inches) apart if they share the same frequency.

The GT23M-TM transducer, being a transom-mounted model, is not recommended for:

Sailboats, due to excessive rolling.

After installation, test the depth sounder in open water:

Turn on the chartplotter with the boat in the water.Drive the boat at low speed, then gradually increase speed while monitoring the chartplotter.If the sonar signal is lost or severely degraded, note the speed at which this occurs.Return to the speed where the signal was lost and make moderate turns in both directions while observing the chartplotter.If signal strength improves while turning, adjust the depth sounder to extend 3 mm (1/8 in) lower beneath the transom.Repeat steps 2 to 4 until the degradation is eliminated. If the signal does not improve, move the depth sounder to another location on the transom and repeat the test.

The Garmin GT23M-TM transducer, being a transom-mounted transducer, is compatible with all hull materials.

Yes, you can use multiple depth sounders simultaneously. If you use two sounders with the same frequency, they must be mounted at least 60 cm (24 inches) apart to avoid interference. You can operate two sounders with different frequencies simultaneously without this distance restriction.

Yes, the Garmin GT23M-TM transducer is suitable for towable boats. It is designed for easy installation and removal. However, it is vulnerable to external damage from trailers or underwater obstacles.

Yes, it is important to note that cutting cables connected to the depth sounder voids your warranty.
