[PSUBS-MAILIST] Depth Sounder

[Alan James via Personal_Submersibles]

 Just did a calculation on the "Under Pressure" program of a 1&1/2" disk of epoxy fibreglass that is 1/4" thick. It is supported with a 1/4" flange so the area the transducer would mate up against would be 1" diameter. I got a result of 2,285ft crush depth. Also saw in a transducer instructional that the manufacturers shoot-through-hull transducer with shoot through up to  .75" thick fiberglass.Alan

  Jon, Just wondering why you want to interface your depth sounder with your computer. Is this instead of the standard boat display module? Alan

 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.
