I do not think there is solo tech certificate, but I do know some who do solo tech dives. I personally do not do solo tech dives and think a qualified buddy/team with that extra brain is very important for tech diving because of the risks involved. Planning tech dives is much more involved and you usually dive with people you know and the typical "instabuddy" scenario is not really a thing.Haha that's great. Is there a separate certification for tech solo diving vs recreational? Who did you get those separate ones through?
I got old and menopausal and became a grumpy insomniac. Travelled a bit, got dive buddies all over the world, got no one here who appreciates a 2am call asking if they want to go night diving...Pretty simple really.
She told me I was experienced enough to exit on my own.
Right now in my work group I have the lowest air consumption rate and highest cold tolerance (we're in Maine, so not as cold as Denmark, but we get to 7-10C in wetsuits) so usually my dives are cut very short by the group. Do you dive night or in caves solo? Or are the lights more signaling/just in case something happens and you're out on or in the water past dark?
