Think it was just a single hydrophone for school use; but some the Master and Senior Chiefs probably know better than I. Problem with putting a passive system in the Gulf is the high ambient noise levels what with all the shipping and myriad of oil rigs and oil/gas exporation. Just saying. EKD
I am only going to commit to this watch bill rotation if they can run a "snake" from BDA to the GOM and guarantee me another 3-year tour (accompanied) in Bermuda.
P.S. Our cruise/visit to BDA in May 2012 was nothing short of spectacular !! Got to visit with two of our Bermudian couples - last seen 35 years ago. Got to go on former NOB (rough shape) - and see some of our former homes & haunts.
