using the depth feature on a garmin gps60

[gary3029]

I have an an old incastec analogue depth which works fine, however I would like to upgrade to a digital readout. Was looking around when I suddenly realised I use a garmin gps60 on the boat and it has a section for depth readings etc. I was wondering if the analogue depth unit I have would be classed as a NMEA device? Would this unit be able to talk to the GPS60 if connected?
Thanks
