What Defines a "Tech" Diver

[Kay Dee]

No one can predict when a dive might become a so called tech dive..

A dive never just becomes a tech dive. Tech dives are planned pre dive.

Care to share that?

Bordering on violating the TOS, i.e., providing unsafe advice on SB.

How is his statement coming anywhere close to giving dangerous advice.

The definition of can is the ability to. If there is no physical overhead you can come straight to the surface. However you should NEVER do so because of the risk of DCS especially if you have virtual overhead due to going into deco.

The key words are can and should.

In my view, yes. Whether you approach/plan/execute it as such is a different question.

it's okay to disagree with me and be wrong.

Side note: I am glad to have responded with a joke here, as I discovered the bicker battle emoji. I'm going to use that in every response with you know who! LOL

An equivalent question: if you go into a cave with a single cylinder and one light, is it a technical/cave dive? Damn straight, but a very poorly executed one.

Not the same thing. If you have sudden catastrophic gas loss, can you reach the surface?

Now I wouldn't want to CESA from 180 feet. I have heard (but am extremely skeptical) to someone making the claim that they did on an AL80 without ill effects (if he had skin bends, my guess by his frequent statements of bravado that he would deny it) as they hadn't hit their NDL.

I don't understand the rational behind bounce dives. Whatever depth I'm diving to, I want to be there for a while and look at stuff. Unless I dropped something of course.

First time I exceeded 130 feet, I was taking pictures of Gorgonian fans in Agamemnon Wall in BC. I went down to 150ish feet as I kept seeing one slightly deeper to photograph. I remained within my NDL (per my Oceanic Pro Plus 2.1 - in the early days of my diving), and slowly came to the surface. I did check for skin bends, and fortunately none. I'll admit it wasn't smart as I could have stayed shallower and gotten more pictures. I didn't have to go deeper, I could have gone right or left.

But it wasn't a tech dive.

Can you dive to any depth, and, as long as you do not exceed your NDL, it is a rec dive? Depth has nothing to do with separating rec from tech diving?

Any depth that's reasonable on air? I'd say yes. If I drop down to the deck of the Oriskany at 150fsw, then work my way up the outside of the island, that seems rec to me.

Come on over there’s plenty!

What flavor?

It never becomes a tech dive because there's no such thing, the circumstances of a dive can change during the dive.

What depth is reasonable on air? A pO2<1.4? A gas density of<5.2 or 6.3 g/L? Something else?
