It doesn't look like a tech dive to me. But as far as the forum goes, I'd say any solo dive belongs in the Advanced instead of the Basic forum.Another observation; there appear to be a lot of tech divers posting in a Basic Scuba forum using tech protocols not applicable to Basic Scuba divers.

Still, any rec diver can learn some lessons about predive checks, bottom checks, not making assumptions, and problem solving under water.
