What do you guys think, im sure you have had this topic raised before (just cant seem to find it). I am aware of the recent advances in Rebreather technology (HUD warning lights etc) and was wondering what you guys all think to the above... am i being overly cautious?
there is no such thing as overly cautious. I would repeat myself with the words "ignorance breeds fear and fear breeds prejudice". If you take the time to really investigate the current rebreathers on the market and the science behind them you will be not only a better diver but you will have a informed approach to explaining the benefits and the pros and cons of the units, which I would assume will lead you to diving one.
Its easy to say that they are dangerous and the are complicated beyond the point of practicality. Take the time to really look at what it is they are doing and why, what makes them work the basic science of of the systems .
Start with the KISS philosophy and ideology. You will find a wealth of knowledge on the RBW. Read it all and then form your opinions then read it again and ask questions. repeat this cycle and you will remain ever vigilant and most importantly alive.
you are on the right path!
