Features
Use a serial cable to connect this black-box sounder directly to your chartplotter
for a superb sonar experience. Once you connect your GSD 21 to your chartplotter with
CANnet, Garmin’s 1 MB proprietary network, you can use UltraScroll to provide
ultra-fast refresh rates.
The GSD 21 is a high-dynamic range sounder that performs exceptionally up to 1,500
feet. You can connect it to a dual-frequency transducer (50/200 kHz) for amazing
deep-water performance, and 500 watts of transmit power, or connect it to a
dual-beamwidth transducer for use in both shallow freshwater and deep water, along
with a transmit power of 400 watts.
