I would hope so since I've been in swimming pools deeper than that. Deepest pool I've been to the bottom of was 32 feet I think.

I don't get how anyone could dive for fun, it's scary down that deep :)

If you're comfortable enough to dive to the bottom of a 32 foot pool unaided, I would suggest you give scuba diving a try, assuming you have the opportunity to partake. It can indeed be somewhat scary at first, but again, assuming you're comfortable in the water, it can rather quickly become incredibly relaxing and fun. Being underwater, even at shallow depths, and yet still being able to breathe, is such a weird and unique feeling that I think everyone should get to experience it.

I can't agree with this more! I suggest everyone try SCUBA at least once in their life.

It sure can be, especially when your lungs feel like they're going to burst and the surface appears to be minutes away. I had to dive to 53 feet for my free diving certification and it's very dark down there (seemingly more so than when you have tanks on your back:).

For anyone free diving at that depth, I'd encourage you to ensure there's always someone nearby that is capable of rescuing you.

Shallow/deep water blackout[1] is certainly dangerous with a buddy, but it's deadly if you're alone.

My fear going down farther than about ten feet is how long it takes to reach the surface. 30 feet is a long way underwater.

Rescue is related. I doubt anyone could pull somebody out that's passed out at that depth. You're just not going to have enough air. I had to help someone out of a pool once and the only way I was able to manage was by walking along the bottom with them on my shoulders to shallower area. They panicked and tried to climb me, pulling me under if I did anything else

Getting certified (at least for the association I use) requires that you are able to demonstrate rescuing an unconscious diver at the appropriate depth (after identifying their blackout).

Well done helping that person. Rescuing a free diving blackout has the benefit (for the rescuer) of an unconscious victim.

The pressure on my head hurts at the bottom of a 10 ft pool. I don't know how divers do it...

by pinching your nose and blowing you can equalize the pressure in your ears.[1]

I'm not sure if this is normal but I have voluntary control over my eustachian tubes. Opening them makes a small click that's audible to others if they put their ears up against mine :)

You have to equalize your ears and sinuses. You're feeling pain because airspaces are getting crushed without equalizing pressure.
