GARMIN GSD 25 BLACK BOX MODULE

CHIRP Sonar Module
Compatible with GPSMAP 8000 and 7400 series
1kW Dual Channel CHIRP Module
Integrated SideVü and DownVü technology for sharp, detailed images

The GSD 25 sonar module, connected to the Garmin Marin Network, provides excellent reproduction of the bottom and fish. It features CHIRP technology with DownVü and SideVü functions. The images sent to Garmin chartplotters of the GPSMAP 8000 and 7400 series offer detailed, high-resolution images of what is below and to the sides of the boat.

CHIRP Technology
CHIRP stands for Compressed High-Intensity Radiated Pulse (high compression of frequencies in an electromagnetic signal) and represents the evolution in the field of sport and professional fishing technology. GSD 25 ensures bottom and fish identification unmatched by traditional echo sounders. CHIRP technology performs simultaneous scans of high and low frequencies that, depending on the connected transducer, can go from 28 kHz up to a maximum of 210 kHz with the relative change of the reading cone.

CHIRP technology, integrated into the GSD 25 sonar module, uses a transducer with HD-ID™ sonar technology plus DownVü and SideVü capabilities. Transducer sold separately.
