Any good training videos for targeting/hydrophone etc?

I saw somewhere where there was a hydrophone video. Anything on youtube that is instructional or anywhere else? I'm looking for anything that covers manual targeting and hydrophone use etc.

If you are using OLC GUI mod (or if you not - try it out), there is a brilliant video tutorial for it available at this mod's post. Search mod forum for it, here you have OLC GUI for GWX 2.0 thread:

It's really a great video, covering all aspects of manual targetting with this mod, although the guy is definitely smoking too much

But that video is not really about hydrophone use. The only thing I can think of is the second link in the first post by Dantenoc:

And you might want to consider Raduz' hydrophone proppelor sound-mod. It has a pretty good manual about how to intercept and setup for a kill using manual TDC and hydrophone only. (based on the mod ofcourse)

There should also be a video about hydrophone use by Mittelwachter, but it seems to have vanished from the net. I asked him recently if he could re-upload it but his comp was dead and wasn't sure he still had it all.
