The GSD 20 is a remote, black-box sounder that
transmits 500 watts at 50/200kHz. It’s designed for
use with the GPSMAP® 2006/2006C, GPSMAP 2010/2010C,
GPSMAP 182/182C and
GPSMAP 232 to provide SONAR capabilities to
these units. The sounder module sends data serially
in a Garmin® proprietary format to up to two units
on board. When viewed on Garmin chart plotters,
you’ll see full-featured sounder displays in either
split- or full-screen presentations. Features
include auto-ranging, 2X and 4X auto and manual
zoom, optional fish symbols and See-Thru®
technology, which separates fish from thermo clines
and structure.
Please Note: This
product does not include a transducer. Garmin offers
a complete selection of transducers to be purchased
separately as accessories.
