gotcha you guys well i am nitrox certified and you can go past 110' ft with nitrox. i have done it the past two weekends and one of the weekends was with my instructor for the course. no big deal though with diving air on the blue hole just more less curious i would say than anything though i do like diving nitrox on deep dives due to the way i feel after a deep dive on air just so dang tired. and yes the convulsions does deal with the oxygen toxicity but what i was refering to was switching or using a higher blend of oyxgen at a deeper depth than need be.
