I was diving last year in Beaver Lake and proceeded to do a safety stop after reaching at most 35 feet. My buddy and I had been moving along for 15-20 minutes at this same depth and he proceeded to surface, while I stayed put at 15 feet and did a 3 minute stop. I wasn't too concerned with losing my buddy, being this was
his normal operation to move around not being aware of his buddy, and I could safely ascend, but afterward I asked him why he hadn't stopped. He explained to me that since we had been cruising along at that depth for sometime, there wasn't a need for a safety stop.
Lately I have been reading the AOW manual and the recommendation is to always have some type of safety stop; is this true even if you have been at the same depth for some time? Also during that same weekend I was diving with a divemaster who was more adamant on safety stops - we ventured to 60 feet and did 2 stops on our ascent.
By the way,
this is the same guy (buddy) who went to 80+ feet and then ascended without a safety stop, so I am guessing the manual and the responses I get will be quite contrary to what his explanation was. He did mention afterward that he did get some tingling in his arms. Hmm...imagine that!
