20 is a remote, black-box sounder that transmits 500 watts
at 50/200kHz. It’s designed for use with the GPSMAP® 3006C,
GPSMAP® 3010C,
GPSMAP® 2006/2006C,
GPSMAP 2010/2010C,
GPSMAP 182/182C and GPSMAP 232 to provide SONAR

units on board. When viewed on Garmin chartplotters,
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
