The Split from A&I Yukon thread: Gas Rules in OW Solo Dives thread has got me thinking about my own gas planning for OW dives with a buddy.
Gas planning hasn't been part of the course material for any of the courses that I've taken, and so I've been left to figure things out on my own. General rules such as "return to the boat with 500psi" haven't been particularly useful.
So, I'd like to get opinions on a particular profile.
Assuming the following - non-penetration wreck dive, wreck upright on a 130ft hard bottom, deck at 95 feet. Plan is to dive to the deck so we'll assume a maximum depth of 100 feet to allow a bit of wiggle room. The site has little or no tidal current. For the curious, the wreck I am using in this example is the HMCS Saskatchewan.
Diver is using a 3500psi 100cf tank with a 19cf pony. The diver's buddy is equipped similarly.
What is your gas plan for this dive and why?
