        <DIV dir=ltr>Hi Hank, 
        <DIV><BR></DIV>
        <DIV>I asked at Carderock over a decade ago and was told the
cost would 
        depend on setup time, which varies depending on how much
instrumentation 
        you want during the test, but that a typical figure was around
$27K. 
        Waaaay beyond my budget. Dale Heinzing tested Snoopy somewhere
on the 
        West side of Canada at a lumber yard. Snoopy went in the tank
alongside 
        the lumber and must have been pretty well disinfected, but the
scary bit 
        was that they released the pressure almost instantaneously,
with
a bang. 
        That test was  to only 400' so not really sufficient for a
Nekton, 
        but it might still be of interest since I think it's relatively
close to 
        you and probably was inexpensive.</DIV>
