Description
The Garmin GT41-TH is an all-in-one 12-pin thru-hull transducer that combines traditional 50/200 kHz sonar with Garmin ClearVu and SideVu CHIRP scanning sonar (260 and 455 kHz). The 600 W traditional channel reaches 1,500 ft and performs well in rough conditions, while the 500 W per element scanning sonar gives picture-like detail below the boat (ClearVu to 1,000 ft) and wide structure coverage to the sides (SideVu to 750 ft). A fairing block, isolation plate and bushings are included so it can be flush-mounted on hulls of up to 25 degrees deadrise and on metal hulls, and at least one anti-rotation bolt is required. A built-in fast-response water temperature sensor is fitted. It connects via a 12-pin sonar port to compatible Garmin chartplotters and the GCV 10 sonar black box. For higher-deadrise hulls or twin-transducer SideVu, see the GT41-THP pair.

Sonar
| Sonar types | Traditional sonar plus Garmin ClearVu and Garmin SideVu (CHIRP) scanning sonar |
| Traditional frequency | 50/200 kHz |
| Traditional power | 600 W RMS |
| ClearVu / SideVu frequency | CHIRP 260 kHz (245-275 kHz) and 455 kHz (445-465 kHz) |
| ClearVu / SideVu power | 500 W per element |
| Maximum depth | Traditional 1,500 ft; ClearVu 1,000 ft; SideVu 750 ft |
Beam
| Traditional beamwidth | 40 degrees (low) / 10 degrees (high), -3 dB |

What sonar does the GT41-TH provide?
It is an all-in-one transducer providing traditional 50/200 kHz sonar (600 W, to 1,500 ft), plus Garmin ClearVu and SideVu CHIRP scanning sonar at 260 and 455 kHz (500 W per element, 1,500 W total; ClearVu to 1,000 ft, SideVu to 750 ft).
Does it come with a fairing block?
Yes. A fairing block, isolation plate and bushings are included, so it can be flush-mounted on hulls of up to 25 degrees deadrise and on metal hulls. The fairing block is shaped to the hull (maximum cut angle 25 degrees).
What do I need to display its sonar?
It uses a 12-pin connector and connects to compatible Garmin chartplotters that accept a 12-pin sonar transducer, or to the GCV 10 sonar black box; some combinations require an adapter cable.
Does it read water temperature?
Yes, it has a built-in fast-response water temperature sensor.
