The interesting "spooky" origins and related incidental history of the Catalina Hyperbaric Chamber to the Lockheed Corporation's Skunk Works, the US Air Force's SR-71, a US Navy deep submersible vehicle, Howard Hughes and the CIA: (copied and abridged from: History > USC Catalina Hyperbaric...

Sometimes you have to yield to that gut feeling, to just stay surfaced and "let it go". . . In order to avert hubris -no matter how skilled or experienced or in-control you believe you might be. I dropped and lost a disconnected QC6 gas source on surface recovery today -a configured UTD...

Scary stress reaction in an experienced cave diver and Scuba instructor, after a wing inflator detachment malfunction and an active physical exertion kicking ascent to surface with double sidemount cylinders, further compounded by surfacing in a potentially low oxygen/high inert gas asphyxiant...

About Us – Pacific Grove Hyperbaric Chamber

Here's a comprehensive Open Circuit gas plan/turn pressure exercise for a planned wreck penetration at 100fsw depth (4ATA) for 30 to 40 minutes max bottom time on Nitrox32 and O2 deco. In this case, the plan is complicated by dissimilar tank sizes and unequal breathing rates between the Buddy...

Finally as a fun aside, I've been trying for some time to convince my dive buddies here in the States using D15 Tanks (i.e. double backmount manifolded Faber steel 15L cylinders for 30 liters/bar total, same rating as both the double Faber HP117's and HP120's ), to at least use a BAR SPG as a...

Spacex Launch Vehicle/Booster Rocket and Un-Manned/Manned Capsule Recovery:

First read about it in some of the old Rec Scuba & Yahoo newsgroups; and AG mentioning it as a last resort contingency for overhead egress during my advanced wreck class in Dec 2005 (but not actually performing the skill during training). The first time I actually did it was for real on single...

Modified Thirds,Turn-Around Pressure and Lost Buddy Search Gas Availability Calculations are much easier in metric with a bar SPG. . . Suppose you originally planned a wreck penetration starting with 200 bar at the entrance, with an openwater Rock Bottom of 50 bar. 200 minus 50 bar equals 150...
