very good article..I am new with only12 dives its bad there are people like that out there that ruin it for new people like me..believe me when i dive with my buddy of 10 yrs and over 200 logged dives i pay close attention to what he says and obey what he says..call it morbid but i watch certain videos on youtube about scuba deaths just to keep me in reality check and what can really can happen if your in 20ft or 90ft, i cant believe that he had the audacity to argue with you after quite possibably saving this man's life,and as far as him leaving you, I was taught to remain no farther than 1 finkick from your buddy,i just did a dive at a quarry with about 1 to 2 ft viz and i made darn sure i was right buy his side, the only referance point we had was the wall everything was almost 1ft to 0 viz,it was also the same quarry i trained in,I'm sorry a newbie gave you so much grief and made your dive so unrelaxing..but it sounds to me you would be a safe person to dive with...I've hear alot that ppl dont like diving with new people which is why i do what im told and when to do it,hope you have better dives Thanks Kenney
