Garmin GT51M-TH Thru-Hull Transducer for CHIRP Fishfinder

Garmin GT51M-TH is a thru-hull transducer designed for high-definition underwater imaging, ideal for use with traditional fishfinders and advanced CHIRP technologies.

Technical Features and Functions

The transducer integrates three distinct CHIRP technologies:

  • Traditional CHIRP: operating at 80-160 kHz frequencies with 600 W of power, it enables precise detection of fish and bottom structure down to 549 meters in freshwater.
  • CHIRP DownVü: operates at 260 kHz (245-275 kHz) with 500 W of power, providing high-definition vertical images down to 305 meters.
  • CHIRP SideVü: operates at 455 kHz (445-465 kHz) with 500 W of power, delivering sharp side-imaging views down to 229 meters for a detailed picture of the underwater environment.

Installation and Construction Specifications

The GT51M-TH model is suitable for hulls with a deadrise angle of less than 25 degrees, ensuring optimal installation for efficient transmission and accurate detection. The transducer is equipped with a stainless steel stem, fairing block, isolation plate, and bushings to ensure mechanical stability and long-term protection.

Additional Technical Specifications

  • Beam angle: Traditional from 24° to 13°; ClearVü/SideVü from 2°x51° at 260 kHz and 1.4°x29° at 455 kHz
  • Cable length: 5 feet with an additional 30-foot extension for complete integration
  • Temperature sensor: integrated and fast-response for monitoring thermal and environmental conditions while in the water
  • Connector: 12-pin for a stable, secure connection with compatible Garmin fishfinders

Benefits for Freediving and Spearfishing

The combination of multiple frequencies and power levels provides detailed, accurate visualization of both bottom structure and fish presence, a key advantage for spearfishing and freediving. Clear transmission of vertical and side-imaging views supports orientation and analysis of the underwater environment in high definition.
