Re: [PSUBS-MAILIST] in-water testing session completed

[Jon Wallace <jonw@psubs.org>]

David,

Thanks for your research and work on this project.

We still need open water testing in depths approaching PSUB capability 
since the shallow water likely set up many reflections that either 
helped or hindered the range.  I would concentrate further testing 
efforts at finding someone who can perform deep water (150-300 feet) 
testing in open water.  I have no idea if the results will be better or 
worse, but it seems like it is data we should have for completeness.  
The 420 feet horizontal distance you reached exceeds the range of K-sub 
operational limits, so knowing how the unit operates at depth and with 
an equal or greater area of width (300 foot cube?) is important.  I'm 
not sure 35 feet of salt-water at the convention is an ideal test bed, 
however it will certainly be interesting to compare salt-water results 
with this unit to those I found with the pinger up in Maine.

Jon
