RE: [PSUBS-MAILIST] Hydrophone Construction Article

["David Bartsch" <dbartsch2236@hotmail.com>]

Jay,

  I have seen a simular article on these dipping hydrophones before. I 
found it so intresting that I made several using 35mm film casings.
  In short, The performance was not what I was in need of in the way of 
fine detection, The mineral oil was difficult to work with without spilling, 
and pressure killed them within a short time.
  I did find working with them to be fun and a simple set of instructions 
on the web helped me along the way. Some used eletrit mikes while others 
asked for piezo elements.
  I am sure that once he flooding problems are solved on the disk type, it 
will work well for many of us. Were you ever able to hear with the 
hydrophone provided to you? Do you think you can redesign it to withstand 
pressure?
  Thank you for the article again as it was informative reading.
