What’s the dumbest thing you've done?

Almost ran out of air on my first attempt at spear fishing-fortunately for me I was only in about 30 feet of water but it was an eye opener.
Then once I jumped in with no weight belt (HELLO BUDDY CHECKS). I didn't know until my tank started getting low. At that point it was a struggle to stay down but once I found the anchor line I was fine.
Anyway, I think both of these were done in my first season of diving. I hope I am better at this now.

Tried to have an intelligent, adult conversation with some people.

Oh, dive related. I do at least one dumb thing per dive. If I don't, it's not a good dive.

Bought a used air integrated dive computer at the tent sale of the dive shop for like $45, so I figured it wasn't a bad deal because the hose was worth $30.

Hooked it up to my reg, turned it on and the damn thing was giving wacky pressure readings, took me a few moments to realize it was reading bars... oh well just multiply everything by 15 and I should be good.

First dive with the computer is solo on a deeper wreck, i get down to the bottom and check on the depth... it reads 563!!! (or something like that) Well now i am bummed, i got a planned deco dive, no back up depth guage or computer and now this POS isn't working.

I figure i can do 10 minutes and just do a little deco on the way up, so i continue to dive. The air pressure is dropping as expected, although multiplying by 15 to convert bars to "real" pressure of psi is a pain.

After about the 4th time I look at the computer i realize there is a decimal in the depth reading... The depth is 56.3 METERS, not 563 feet. What a pain, so now I realized i would have to multiply depth by around 3 to get feet. (Even at 170 feet, i knew it required a factor of about 3.3, but that is just too much math to do.

After a few months, I actually learned to dive pretty well with the bar and meter read out.


BTW, I don't care what people say about the metric system, feet is a much more precise and reasonble means to measure depth, plus who the heck wants their depth reading with a decimal in it? Hell fathoms would have been preferable to meters!
