The OSTC3 have a fibre input port, for a digital signal. That digital signal can be generated from the HW Hud[1] or a ppO2 Monitor[2]. There are some rumors of a OSTC cR. To me it looks like a OSTC3, in a OSTC2C case, with a S8 analog input. > Do you use it as DC or BT? I run my OSTC3 as a DC, and my Suunto Vyper in Gauge mode in my pocket. There have bin some long running debate about DC vs. BT in the tech diving community and the old truths about DC isn't true anymore, like some of the FUD GUE is still spreading[3]. It might have bin that case 10-15 years ago, when a trimix computer was 10-15 times more expensive than today. GUE does a lot of things right, and really good, but on the subject of DC's, i think they are completely wrong. When your pushing the limits, ex, deco diving, wreck penetration or cave diving you always need proper planing. Gas planing, time planing, deco planing, task planing and so on. I think diving with a DC is a great way of verifying your plan on the fly and adapting your plan. If I've got a sonar depth of a wreck at 60m and when we actually hit the wreck its 68m the plan becomes something quite different. Instead of staying at 60m or calling the dive, you have the option to shorten the bottom time and get some sort of dive out of it. The same goes for the opposite, which is way more common. The sonar depth might have said 65 meters but all the interesting bits where on 55m. Then you can extend your bottom time at 55m and use your expensive helium in a sensible fashion. //Anton 1. http://www.heinrichsweikamp.com/?id=79 2. http://www.heinrichsweikamp.com/?id=405 3. https://www.globalunderwaterexplorers.org/equipment/config - Computer Diving -- Anton Lundin +46702-161604 _______________________________________________ subsurface mailing list [email protected] http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
