Jay & David,

This is what I was getting at originally when I gave examples of operational variations of similar products on the market.
Also the above post gives weight to my suggestion that if you hung the boat unit lower in the water further away from the surface noice,
you may find you hear better despite the proliferation of croaking fish in your waters. If you're experimenting with this unit at the conferance
why not take an extra 50ft of wire & test this out.
Kind regards Alan

From personal experience, a good rain squall or very high winds will produce sufficient oceanic noise that it will swamp the type of equipment we are discussing here. Thanks for reminding me David.

Alan,
The point I think he was really making, and it is a very valid one, is that the ocean is a very unpredictable place and therein is contained all manner of noising making aquatic life.
If in addition to these noise sources, you add but a simple rain squall, the effects on a passive listening device could be equally unpredictable as to its performance. There are just so many variables to contend with in the broadband spectrum of sound.
