There was a thread not too long ago on the Spare Air version marketed for Nitrox. Some felt it was a marketing gimmick, if I recall. What @BRT said above was also discussed. I'll try to find that thread.
By the way, weren't you in my Fundies class with Doug Mudry in 2014?
Lorenzo Hi!
How are you?
Yes, I was in that class. Haha all the memories of the little house on the springs just came flooding back!
It was one of the turning points of my dive training. Was worth every penny and second of my time!
I got a provisional and had planned to go back after I got more diving under my belt. See, I took that course with only about 30 dives experience haha. Still practice most of the methods but now that I get to help new divers getting certified with PADI, I do change up teaching styles with their curriculum in mind. Want to continue with the training at some point with GUE. One of my favorite parts of diving is getting to learn all the best training methods and techniques from all the training organizations. Thank you kindly for the link to that article on SB, will check it out.
What are you up to diving wise these days?
