Dive #147

Location: Ormestad, Gullmarn, Sweden
Time down: 15:04 | Time up: 16:19 | Divetime: 75 min | Max depth: 49.1 meter | Average depth: 21.8 meter
Water temp: 10° | O² used: 140 litre | Dil used: 260 litre | Total RB divetime: 79h 10min

Exam dive on the RAID RB 50M Deco TX course. Max depth on course is 50 meters, the MkVI maximum operating depth before the depth alarm kicks in is 48 meters with the Trimix 48m battery. I logged 48.1 meters on the MkVI, and a meter deeper on my OSTC 2N computer. Great multilevel dive, 48/15, 30/20, 18/1, 15/1, 12/1, 9/3 and 6/14. Dive went smooth and the 19/26 mix I had in the unit kept my head clear. I am now certified to 50 meters. This is what Rebreather Diving is all about. Coming up to the surface after 75 minutes in the water, having spent a total of 400 litres of gas.

Second dive of the day, and a planned deco dive without any drills. Real stops at 18m, 15m, 12m, 9m and 6m. The poseidon MkVI did what it supposed to (as it use to). And it was a pleasant dive. Spotted a huge king crab (Lithodes maja) and loads of squat lobsters (Galathea strigosa).
