hey folks something that occurred to me. From what I can see on here a lot of folks are doing their "open water" dive training in calm lakes with very little if any current,wave action tides etc. Would it therefore make sense that if they are trained in such calm conditions that they should have a "checkout/sighnoff" dive with an instructor when perhaps doing a boat dive in the ocean or a shore dive in a bit of a sea. -Not a full on "course " as such just a single dive. Happy to stand corrected here.
