Hydrophones

["Danny Meltzer" dannymeltzer]

Hi all,

I searched for previous threads, but didn't see anything that had this
info...

What are some brands and models of hydrophones that people use here?

I assume there are scientific models that are priced into the
stratosphere, but what are the options from bottom to top?  Of course
I know I could build my own too.  We'll see about that.

Thanks!

Danny
