Garmin GT21 Transom or Through-Hull Probe - 2D/ClearV

GT21 transom or through-hull transducer - 2D/ClearVü - GARMIN

There are two types of GT 21 transducers: 

- a transom transducer - 8 pins: GT21-TM

Transom transducer optimised for significant depths and challenging conditions.

It provides optimal rendering of underwater bottoms, submerged structures, and fish.

It offers a power of 500W in DownVü CHIRP mode (260/455kHz) and 600W in traditional 2D mode (50/200kHz).

- a through-hull transducer - 8 pins: GT21-TH

Through-hull transducer optimised for significant depths and challenging conditions.

It provides optimal rendering of underwater bottoms, submerged structures, and fish.

It offers a power of 500W in ClearVü CHIRP mode (260/455kHz) and 600W in traditional 2D mode (50/200kHz).

Suitable for any type of hull with an inclination of less than 5°.

2D CHIRP FUNCTION: 

Sonar devices operating with 2D chirp allow for:

- better target definition

- more detailed target discrimination

- a clearer fish arch

CLEARVÜ CHIRP TECHNOLOGY

ClearVü™ technology provides a detailed image of the fishing environment around the boat and an accurate representation of structures beneath the boat.

Classic transducers emit a conical beam, while the Garmin ClearVü™ scanning sonar technology emits two narrow beams whose rounded shape allows for scanning the bottom: These beams thus provide a clearer image of the environment beneath the boat.
