I just checked the hydrophones, there appear to be no problem at all with t=
hem ..
what makes me really skeptical is that only one of them picked the sound - =
if it was something distant (like a radar) both of them should have picked =
the sound..
I tend to think the source was located really near the hydrophone.
Just to note that after I buried them in the sand I used two small stones t=
o keep them in place - maybe that explains sth ?
