I just wanted to say that I am deeply impressed with scubapro's customer service. I know there have been mixed reviews of this historically. But I had some questions about the G2Tek computer and emailed through the site. They were very responsive and ultimately when they weren't sure that we were on the same page they sent me the number of their Florida sales rep who turned out to be David Rhea. He spent 20 minutes on the phone with me sharing a lot of his wealth of knowledge and fully clarified a misrepresentation that has been out there about the SOS feature on Scubapro computers.
In short, the manual for the G2tek reads as though lockout does not occur until a diver surfaces (ie an absolute depth of 0.8m or 3 feet) after blowing off a deco stop. However, on this forum I have seen people stating the depth is relative to the deco stop. This concerned me so I asked about it and he clarified that the manual is correct. The lockout occurs when an absolute depth of 0.8m is maintained for >3 minutes after blowing off a mandatory deco stop, which on the G2 tek is defined as a deco calculated from GF 100/100. None of this is particularly relevant to me at this time but I like to know how my equipment performs in all use cases so I wanted to understand its function and whether or not it would be safe to use once I get to the level of deco diving. They explained that they installed this function to ensure that the data from that dive is not lost for the usage of a hyperbaric physician. The 3 minute duration allows for a diver in extremis to surface briefly to call for help, pass of an injured buddy, etc. and still return to depth to complete their deco. If you stay longer than 3 minutes it's too late and you're bent anyways. He made a good point that if the 3 feet was a relative depth there would be a million reports of lockout all the time when doing deco because people aren't generally good enough with buoyancy control to stay within that margin reliably.
