I have been searching for the Los Angeles, an 1890s woodenboat wreck. Finally found it on a coast map. A couple of friends of mine at a sports bar during a Raiders game asked me, Whats that map for? I said, Treasure. They said they have a RIB with a big engine that could get me out there to the site and back, which is a long haul south, then a longer haul beating back against the wind north.
So we agreed to split the treasure 3 ways: pilot, navigator, & diver. What a blast!
Max depth at the wreck site is 120 fsw.
120 fsw / 33 fsw + 1 = 4.6 ATA
1.4 ATA / 4.6 ATA = EAN 30
For a relatively shallow dive like this, to 120 fsw on EAN 30, I can set my Suunto Vyper dive computer to monitor the N2 diffusion and use its decompression model for the egression. I havent decided whether to use my PST 120 or my twin PST 80s.
I will either sling a 40 cu ft catalina or a 65 cu ft luxifer with EAN 40 in it for deco if needed and as a pony.
(1.6 / 0.4 - 1 ) x 33 = 99 fsw MOD for the pony
Good luck with your own search and recovery, Sailor! Dont forget the math. And the pony.
