Bad scuba advice you've received

[Ski_Lounge]

When you begin your ascent, dump all the air from the BCD before ascending. That works just fine for a properly weighted diver in a 3mm suit. A diver in a 7mm suit, even if properly weighted, will immediately begin to plummet to the depths below.

Thank you for pointing this out. I do remember being taught exactly this in OW, and it's absolutely disastrous for an over-weighted diver. I experienced my buddy plummeting (because... over-weighted by instructor) during our training. This is truly awful for a beginning diver.

Hence the few. Of course the way helium is going it will be true more often as time goes

And not be replacing expensive parts every few months.

I am going to list two examples of truly bad advice that are actually taught by some instructors.

1. If you see an OOA diver going for your primary regulator, cover it with your hand to prevent it while you reach for your alternate to donate. Yep. That's what we want--a hand fight with a panicked diver over one of the two working regulators.

This is why you should carry a BFK, amiright? Don't bring a fist to a knife fight!

This dry snorkel is the best snorkel made, right along with always have a snorkel on your mask.

A well known diver actually said something close to that, although it was later claimed he was misunderstood. He was not just talking about his primary regulator, though--as most people understood it, he was talking about any regulator.

Getting started in tech diving...
You know what you are doing, you don't need intro to tech. right and wrong. Right, don't need it from the people who said that. Wrong, it has been a rough transition.
Same people also sold me on just doing sidemount instead of backmount.

Diving got a lot better once I got better advise.
