DMI is very reliable, and I've used them many times. However, what they may have meant talking to rmcneny is that their new DMI Phoenix depth sounders use active transducers, transmitting an NMEA 0183 signal. The Datamarine Corinthian sounders used passive transducers at 197kHz, 200kHz, and 210kHz. Assuming you have one of these last three, you can probably cobble together a working system with almost any instrument head that uses 200kHz PASSIVE transducers. I have a customer who is happily using a Datamarine Corinthian S200DL instrument with a 200kHz Garmin Transducer (the opposite problem). Remember, almost all depth transducers are made by Airmar. Having said all that, if the instrument were mine, I'd send it to Steve at DMI for repair. They will give you a guarantee for several months; Ebay usually gives you 7 days or less.
