i'm assuming that's just for telling you which direction the surface is, and to guide you there, not for keeping you afloat. i hear figuring out the way out of the water is pretty hard when you're several feet deep in an overturned car, so yeah
another method i've read is to just blow a couple bubbles and follow them, but that of course doesnt have the easier float part
#106 - anon (07/16/2015) [-]
If only there was something you're supposed to wear while out on the water in a vessel. Maybe it could be bright orange too so if you fall in they could see you.

Did the research because this ticked me off a bit, you actually need to be careful, the pressure will actually hurt your ears. You need to be a least a regular diver to be able to naturally tune your ears and eustachion tubes (back of your throat to the middle of your ear).
You rise too fast, you get too much pressure, unless you've handled it on a regular basis.
#55 - cursedfool (07/16/2015) [-]
Literally just read this, you aren't getting it.
They even list multiple manual things you can do to avoid ear injury. It really is a thing.
#58 - iwillrulenorway (07/16/2015) [-]
i'm fully aware of that, but the page is saying exactly what I'm saying, so i don't get what we're disagreeing on here.
are you referring to the point where it says ''During ascent, if the expanding air can't be vented, the cavity pressure increases, resulting in discomfort'' ? and while that's true, such injuries are caused from having a cold and therefore blocked sinuses. if you're healthy (and you should be before diving) this will not happen.
#60 - cursedfool (07/16/2015) [-]
"This type of injury can range in severity - from mild to extreme. A sinus or middle ear injury may occur suddenly and lead to inner ear damage. For this reason, divers should know and use the "clearing," or equalizing, maneuver that works best for them."
Straight from the article. Read it again.
Rising too fast causes injury, in the ear and sinus, that people have to be careful about.
You do not have to be sick to have your ears rupture.
Look, and be amazed.
#63 - iwillrulenorway (07/16/2015) [-]
aww fuck I just can't hold it in.
yes rising to fast is harmful, why? because your bode does not have time to adjust to the pressure causing a build-up of nitrogen bubbles in your blood and tissues, and the rapid expansion of the air in your lungs, to avoid decompression sickness (nitrogen bubbles) you should rise at a steady rate of ca 3 meters per 10 seconds and slowly exhale.
and while the other airspaces in and around your body also expands (sinuses, mask, ect.) these adjust automatically, and the bcd which you also have to deflate going up ofcourse
#64 - cursedfool (07/16/2015) [-]
Holy shit, you're autistic.
On average, human bodies do not regulate pressure the same, nor at the same rate.
That is why they list so many techniques (for relieving pressure), preferences, and other diving tools to compensate for this.
It isn't done automatically, because if it was, there would be no chance for injury. And this is a very common thing to happen to frequent divers.
They even RECOMMEND taking time off of diving to allow more time for pressure to equalize in your head, so another injury doesn't occur, because it doesn't do it automatically, you still need to practice those exercises to relieve pressure.
This is my last comment. This is getting rhetorical.
#65 - iwillrulenorway (07/16/2015) [-]
what you're talking about is surface time and decompression, which is another thing altogether.
but if you feel like responding one last time I would ask you this.
are you even a diver? I mean it's always good to be careful like you are, but it's another thing to be carefl when you don't need to be
#67 - anon (07/16/2015) [-]
We were talking about how constant rising will cause injury.
You said it isn't anything to worry about, because you can do it.
Not everyone can do those exercises like you, or they may not even know them.
It's literally all fun and games, until you watch someone pass out underwater, with their ears bleeding profusely, because they rose too fast or didn't do the pressure exercises/know their limits.
Sure, people can dive without injuries occurring, doesn't mean it won't happen to someone who doesn't know how to regulate pressure.
#73 - iwillrulenorway (07/16/2015) [-]
I get what you're saying man, but I certainly didn't need any training, and i can't imagine that anyone would. but then again I've been a boat owner and swimmer since I was 4-5 years old and, so I'm fairly experienced when it comes to these sorts of things, might just have forgotten that i do it automatically
#86 - cthulhusprophet (07/16/2015) [-]
iwillulenorway is right though. Your eustachion tubes can blow during decent. During accent the pressure flow is reversed to a point where they will equalize naturally. The problem with accending too quickly is decompression of the gas in your bloodstream. Not your ear.
#102 - cthulhusprophet (07/16/2015) [-]
If you are accending from a depth at such a speed that it could cause your eardrums to burst you would probably have more to worry about than yur ear drums. I'll consent that it is possible in the most extream sense of the word to do. Your ears do an amazing job equalizing while accending. I've been diving for 4 years and have a Master Diver and a Rescue Diver certification. I've never seen/heard of a burst ear drum from accent.
#108 - cursedfool (07/16/2015) [-]
If you've never seen this happen, I highly doubt you're a frequent diver. The ears bursting is a very severe case, but most likely seen should be passing out, or huge headaches. Please at least Google some facts or.. something, I don't know. I'm not sure what could help you, specifically.
#54 - iwillrulenorway (07/16/2015) [-]
are you? I am indeed a diver, and the feeling you're describing does not happen to me on the way up only on the way down.
btw when you're going up the air behind your air-drums expand and automatically goes out your sinuses, which is why you don't feel anything in your ears.
please excuse my poor English but what did you think i meant?
