[PSUBS-MAILIST] Depth Sounder

[Alan James via Personal_Submersibles]

 Jon, firstly correction, the depth rating I'm getting for that 1/4" thick disk is 4,474ft. I will be going this route! The depth sounders normally have charts with them & the charts are continually being updated and with GPS, put you in location when you are on the surface. If you find anything of significance like a treasure chest; you can go straight up to the surface & mark it with a way point on your maps. Also having the display enables you to see objects of interest below you. Alan

  Yes.  I want everything (or as much as possible, realistically) on my primary display and feel that I really only need a digital numerical representation of depth rather than the functionality of a fishfinder or side-scan sonar.  However, some traditional fishfinders have a NMEA output that can feed other displays/instruments.  It may turn out that such a fishfinder is an appropriate solution and in fact cheaper than a transducer specific to my needs.  However the question would still remain, what is the reach of the sounder in a real world application.

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