Beware - big brother may be watching and tracking you even while we are diving.

I wonder what the source level of these sonars is?

Or better yet, Big Brother might be watching a terrorist trying to blow up a bridge or something.

We figure it was active sonar that we were hearing three years ago on this dive. I'm sure that they had us tracked the whole time.

If you heard it, it you weren't being tracked. Sonar in the audio range doesn’t have the resolution to pick up small targets.

Your link isn’t working. Were you diving someplace where the Navy or CG might think you were a threat?

I fixed the link. We were within a couple of miles of a nuke carrier group.

dlndavid,

That's even better as far as I'm concerned. You won't find me complaining after putting 26 years in the Navy.

Hence your location, San Diego. Sometimes people think that the Gov't watching is a bad thing, I'm glad you don't and I know I have nothing to hide.

In Cape Canaveral...we are trying to develope passive acoustics....an ear that listens...no active sonar
