scuba

(Hours more befitting a scuba-diving shop in Vatican.) Business as usual I would say...although I don't scuba-dive...

In the first example, it seems those weren't scuba tanks, but rather pressurized air containers that are used to fill the real scuba tanks - they are quite a bit larger.

This is something that scuba divers are aware of, because of the way water plays with sound.

It's either that or whoever wrote it believes scuba training manuals or prepaid phone minutes have some relevance to transportation security.

I don't know too much about plane hardware, but I scuba-dive a rebreather which has critical life-support electronics.

Then taking up the sports (which aren't especially dangerous; even scuba diving is safer than inactivity per minute) is a great call.

Relative to other hobbies like golf, skiing, or scuba diving, Magic isn't astronomically expensive.

Having said that, I think these advantages are mostly important for niche uses - scuba divers for example.

I've been using a similar dolphin kick when scuba diving just for playful fun in the water.

I try to travel as frequently as I can to hike, mountain bike, snowboard and scuba.

On several scuba and climbing sites I visit, there is a strict separation between mourning a death and speculating/analyzing the cause.

I have no fear whatsoever of the dark, even to the point that I enjoy solo scuba diving, at night, without a flashlight.

If I had to hazard a guess, I'd say it's because "Tcl" is typically pronounced as a word ("tickle"), so it got de-acronymized like "radar" or "scuba".

There are long-term considerations: the CI destroys any residual hearing and the capability for hearing aids to work so you can't "roll back" after the surgery, you can't do MRIs ever again, you are supposed to avoid high pressure/high impact activities (scuba diving, tackle football, etc) -- although many deaf people with CIs that disregard this advice.

It was a friendly rival to Scuba, and was eventually replaced by Presto, which is not even mentioned.
