Similar but not quite the same.
What AdivingBel and I are describing is not a dive op catering to certain customers but rather recognizing and adapting dives to the abilities of their divers, not a one size fits all approach. My diving would not impact your diving in any way since you might not even see much of me during the dive and you certainly would not be require to adjust your dives to match mine.
The dive you describe that irritated you would simply not happen with the dives we are discussing.
I am curious how your operator would handle divers like the hunters and photog I described in my post. Would they be left on their own and the boat finds them when they surface ?
