The price was right and it has all the connectivity I could possibly need (much like the 742) the display is great and it is a good upgrade from my 8 year old 5" model.

Ron, what model NMEA depth transducer do you have? If it's an older Airmar its talking NMEA0183 at 4800 baud. It should work just fine. Make sure the Garmin communications settings are correct (which port and what baud rate). Make sure it has a common ground and is otherwise hooked up correctly.

I have a NMEA0183 depth transducer but I hooked it to my Nexus server. The data makes its way to the plotter via N2K. But I am certain this will work, unless the transducer itself is broken.
