Gday David,
It would be great if it was possible to get the
Instructions, circuit diagrams, component list and circuit board diagrams or any
of the above, I have been considering having a go at building a hydrophone for
some time now. This would be a good step to get me mobile.
Thanks and hoping to hear from you,
Regards Clive Wood.

Hydrophones
Frank,
I will in the weeks ahead produce
the single hydrophone intended for installation aboard your boat. This is
being done so that you could mount this device early with the use of the
proper thru-hull fitting. It can be placed within a ballast tank and will hear
thru this as long as water is present on both sides. This will not create
additional drag if installed in this or likewise manner. I will set up a small
process whereby many can be produced at the same
time...So....
Does anyone else want a preproduced
hydrophone for installation aboard other submarines or for perhaps testing?
Perhaps the how-to-instructions so that you could build your
own?
I used an all electronics preamp kit and all
electronics 7watt amplifier kit and these worked great together allthough
other electronics could provide equally good results. Go to allelectronics.com
for ordering info. The preamp was less than $10.00 with the 7watt amplifier
close to $15.00. All that is left is a small 12vdc battery and a small project
box to fit it all in withy the panel controls and on/off
switch.
If you want to take this plunge, here is a great
chance to dive
in.
