Sorry, my bad. When I say "technical" I mean that was a deep dive, in strong current with bad vis, in a middle of nowhere, with really ****** weather. My "technical" meant that a lot of skills were involved. I hope is clear(er) now.What I do not really understand is, that you are talking about doing a technical dive, but going up to avoid deco.
The "technical" dives I know, are planned with bottom time, deco-stops, runtime etc. so that the dive-plan should have been discussed before. especially when to start ascending.
You say, you saw him at the anchor while you were above him. Why were you not able to reach the anchorline? Was the current so strong?
I couldn't reach the anchor because it was too deep (-34 m). Moreover, the bad vis didn't allow me to see where the line was, and finally, the current was so strong that was impossible to reach.
