[PSUBS-MAILIST] Depth Sounder

[Jon Wallace via Personal_Submersibles]

Cliff, what manufacturer/model sounder are you using for altitude?  Do you have it interfaced with your computer or is it a separate unit?  I'm looking at NMEA sounders which are relatively easy to interface with microprocessors but are expensive.  Analog depth sounding transducers are much cheaper but I don't know how they present their information.
