Roger,
I have been using the Poseidon pressure gauges for about three years now =
without any problems. It is a very compact and solid gauge. =
Unfortunately I don't think they are imported now (I may be wrong).  I =
run one hp hose from the right-side valve post across the back, under my =
left arm, and have the gauge clipped to the harness D-ring on the left =
side. There is no slop in the hose and the small gauge is tucked in =
nicely and is easy to read. One gauge is all you need.

We were doing some workup dives on the Skycliff wreck off of Boynton =
Beach, Florida a couple of years ago.  One of the divers had the task of =
jumping with the float line chain (free drop) on to the wreck to tie off =
the float (strong current).  We unhook the float chain at the end of the =
dive and use the line and float for decompression. The remaining divers =
descend along side the tie-off diver.  We were stationed on the rear =
platform of the boat while the captain lined up for final approach for =
the drop. The tie-off diver had the float line chain wrapped around the =
handrail because of the tension of the float being drapped through the =
water with about 400 ft (est.) of line attached. A robust snap was on =
the end of the chain.  Well this diver slipped and fell overboard behind =
the boat while it was underway. His Poseidon pressure gauge caught in =
the float line snap and he was momentarily dragged through the water by =
his hp gauge hose.  He was wearing two stage bottles to boot. =20

We got him back on board, bent ego and all (he was an Army special =
forces diver), and examined his gauge and hose.  There was no apparent =
damage, although personally I would not have used the hose even though =
it looked OK.  Now that was a tremendous force on the hose.  I think a =
conventional hose would have easily parted at the gauge connection.  I'm =
sure he is still using that hose.  Many of my dive partners use the =
Poseidon gauge and I've seen only one fail (Poseidon fixed at no cost). =
Its relatively expensive, but so what!

Hope this helps,
Doug Chapman
