| Re: Ice Diving and Cold Water Advice Needed
Wow, great responses. Thanks again.
I'm really hoping to avoid the trial and error business by tapping some of the cold water experience on this list.
The main reason that I'm being so cautious is that CO2 has me a bit freaked out. During the course, we did a dive without sorb in the cannister to experience hypercapnia. I found the result quite surprising. I didn't suddenly notice symptoms of hypercapnia, instead, it was very subtle. I found that it crept in so slowly that I really didn't notice until it was too late. It wasn't until I heard my Rebreather adding gas on every breath, instead of every few breaths, that I realized that I must have excess CO2. I don't know if this is common or not. Probably once I dive the unit more to know how things "should" be feeling, I'll be more aware when something like excess CO2 buildup happens.
Nice to get 3 local responses from people I know.
Marc, I don't think we've ever met in person, so if you're at the quarry and see a guy with obscenely large tanks on his Rebreather, it's probably me - stop by to say 'hi'.
