Garmin GSD20 Sounder Owner's manual

GSD 20
GARMIN invites owners of its
expanded line of GPS chartplotters
to add a new dimension: depth.
With the GSD 20 remote sounder
module, both the fly bridge and the
enclosed helm can view and control
the sonar. When integrated with
the high-resolution displays found
on WAAS-enabled plotters like the
GPSMAP 2006 or GPSMAP 2010,
the GSD 20 paints a beautiful
picture of what’s beneath the boat.
