Scuba diver descends or ascends using proper buoyancy control by inflating/deflating his/her scuba BCD (Buoyancy Compensator device)
There is a scuba diver power-up which you should use in water-related levels
Swimmer, scuba diver, school teacher, Santa,
A scuba diver should not ascend rapidly, because the nitrogen in their bloodstream will lose pressure and create bubbles in the bloodstream. This will cause decompression sickness, which can be fatal.
You can if you have a Boat and enough oxygen. Do not go to far down or when you try to come up you'll have no oxygen.
By going to your local PADI Dive Center and doing you Open Water SCUBA Diver course. You will learn to set up, put on and use all the gear effectively and safely in as little as 3 days
One possible answer involves a forest fire and a very charred scuba diver. During a fire a water carrying helicopter collected water from the sea in order to extinguish it. However the helicopter also picked up the scuba diver, in the sea water, and the diver was killed when he was dumped in the middle of the fire, most likely from a high altitude.
This is an urban legend that turned out to be false. Supposedly the scuba diver was picked up by one of the helicopters that was pouring water on the fire and he ran out of air while traveling. Snopes can tell you more: http://www.snopes.com/horrors/freakish/scuba.asp
A person can only breath air that has the same pressure has his or her surroundings. Under water, the pressure will go up fairly quickly (every 10 meter / 33 feet of water exert the same pressure as that on the surface) and the scuba gear will make sure the diver gets air with the same pressure as that of the surroundings.
The helicopter bucket picked him up while he was scuba diving 20 MILES away from the forest he didn't even realize it until he was doing a backstroke in a bucket 300 miles in the freaking air and when they opened the bucket door the water came out and so did he :( I feel so bad for him Smh..

You would blow up from water pressure.
You don't really have to worry about dying when diving without scuba gear on, If you go under and continue to swim down you will be accompanied with some painful amounts of pressure, so its really up to you how much you can take. experienced divers can go down about 20ft to 30ft because they are used to the pressure. A new diver would only be able to go about 15 ft before realizing it hurts and you want to go back up. There are techniques to reducing the amount of pressure and pain but you still won't make it far passed 15ft without some effects.
