[PSUBS-MAILIST] OTS

Rick,
Glad you are not suffering from the early onset of dementia!
I still have most of the emails if you can't find them in the archives.
Some times the emails don't show in the archives for a while.
If Emile was getting reception 3000ft away you may get even more
with the OTS, but in the specs I've seen they always say that there is a 
broad range variation depending on wave & water conditions.
DNV-GL require a range of twice your dive depth, but how that is 
quantified given the variations due to conditions, I don't know.
Alan

They are more intended for recreational use that OTS but  the units give good quality sound even with the sub at 200 M (600 ft) deep and a Kilometer away on open sea!
