O.C courses

The last 3 weeks have seen me back on OC teaching a mixture of Advanced Nitrox, Tec Sidemount, Advanced Recreation Trimix and Extended Range. Tomorrow it is back to the Rebreathers and day 1 of a Mod 1 on the AP Vision  The photo is of Perko on his qualifying dive, for his Extended Range course at NDAC. http://www.rebreatherpro-training.com/News-diving/OC-courses/19
