Intelliducer for Garmin  

Intelliducer will ONLY show a digital read out for depth and temp. They

WILL NOT show any type of bottom countour.  The Intelliducer is for NMEA 2000 chartplotters that do not have a built-in sounder. If you want to use a transducer that gives bottom detail you will need to add a sounder to your chartplotter (such as the GSD 21 or GSD 22); then get a trandsducer compatible with the sounder.
