a little bit of background info: havent dived in 2 years, but took my refresher course, and am now doing my wreck and digital photography spec.
ok so i was doing my 3rd dive this holiday, and i used up my air VERY quickly, (probably from chasing fish in circles to do my digital photography spec), but at 800psi i let my DM know of my air situation. he said ok and continued going along.
anyways a little time passed and i noticed that i was becoming positivly boyant and had to dump all the air from my BCD to stay neutral, so i checked on my air and it was down to 300psi :11:.
now i should mention the dive was at a max depth of 60ft, but mostly at around 40ft. this was following a 110ft dive with 1hr SI.
i started to get a little paniky so i caught up with my DM and told him i need to assend ASAP, he said ok, so i started to assend with the group. As i got to around 30ft i noticed that i became positivly boyant again, as my tank was getting very low, i was unable to keep myself from surfacing, (my dive computer didnt complain about my assent rate), but this meant i missed my saftey stop.
now sorry about the length of this post, but i have some questions:
1. when ur tank is very low how do u stop urself getting positivly boyant? i had already dumped my air from my BCD. if this was from a deeper level im sure i would have suffered from DCI, and even possibly overexpansion problems
2. i know a safety stop is not necessary if im not within 3 groups of my NDL ( i think thats right) but i did deep dive about an hour before, so i probably should have done the saftey stop! obviously i didnt feel any of the symptoms of DCI, but how long should i leave it before diving again? is 24 hours generally ok?
thanks a ton!
