Does Garmin have a combination sonar sounder and GPS unit for a small watercraft (18')?If so please provide Model Number.
I have looked at Lowrance and Hummingbird products that are Navionics Compatable. Price range $500.00-$1,000.00. Some are DSI units. Ihave been advised that Garmin has the most complete and easily understood instructions booklets. I have a Garmin E-Trex GPS and Garmin 120 Rhino radio now.
Hi,The current version is the GPSMAP 421S - which has the sounder (with transducer) and and GPS capability - but the unit retails for $499. This is about as least expensive as you are going to find, for a combination unit, with transducer. Amazon has a unit with a discounted price available here.The manufacturers keep adding bells and whistles to the units (DSC calling, etc.) so the price is in the upper range.Thanks,Rod

Is the GPSMAP 421S Navionics Compatible?
Hi,Do you mean using the Navionics Media cards? If so, no, Garmin has their own - if it is a device that uses the media cards you have - and does NMEA input and output, then Garmin can communicate to the device using NMEA interfaces.The only units that are compatible with the Navionics cards are listed here.Thanks,Rod
