All you guys, saying, that one should buy a cheaper "beginner" Rebreather... WHY?!
I started with a cheap, used Inspiration Classic, and I got less than 20 hours on it, before I got my Boris... Why?! Because I had a wrong feeling of the YBOD. It just didn't feel right... Why on earth would I liek to dive a unit, I already knew I wouldn't like to do a trimix course on, then that it the goal!?
I agree on, that you just don't buy one Rebreather for the rest of your diving career, but I do believe, that one should buy the unit one likes the most... And a Boris is not that difficult to learn to dive... As far as the CIS concerns, I have no idea at all... Simply don't know anything about it... Well.. I do... It's yellow, right?!
