One can go to take free diving lessons through Australian Freediving Academy and Open Freediving course in United Kingdom. Free diving is also available at a South Florida diving school.

Here are some example CRM softwares and applications, Microsoft Dynamic CRM, most of today's CRMs are web based. But if you are in the automotive industry another cost effective desktop based CRM is called Dealer Elite CRM.

seriously? it is not diving and you don't scuba to breath in air.

Implants do not affect the ability of a diver to descend deep.

A scuba diver can purchase many things for scuba diving at the Air Hog online shop. They can purchase dive knives, dive lights, dive computers, and dive bags which will help them in scuba diving.

Scuba diving.

No.

Ocean trenches are deep, really deep. Scuba equipment won't let you dive anywhere near deep enough.

Many people use a SCUBA suit for diving. Sport divers, police divers and some Navy recovery divers.

They do not dive deep enough.

Scuba regulators, also called 'diving regulators', are vital for scuba divers to properly obtain oxygen from a tank. Regulators are available for purchase through diving specialty stores such as Prime Scuba, House of Scuba, and Divers Direct.

For bouyancy calculations, most regulators are assumed to weigh about 4 lbs.

For recreational divers, they only carry one regulator, but technical divers may carry four (or more!) regulators on their doubles and various stage tanks.

Naturally the air we breath has 70% of nitrogen and only 21% of oxygen, this is done is scuba diving as well. Just oxygen is not enough for living, while oxygen is essential one.

Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.

220 feet is about 67 metres. The pressure of air at this depth is about 8 bar (or atm). Using standard air the partial pressure (20%) of oxygen is 1.6 bar. This is the boundary where oxygen begins to become toxic and can cause serious health problems (and lead to death).

I am a diver with BSAC and the recommended maximum depth is 50m on air which is about 164 feet.

The alternative is to use other mixes of gas which usually require more advance training but they contain less oxygen so it is safer to diver deeper.

Summary, it is NOT safe to dive to 200ft on standard air

Looks like it is most of the time. One thing to keep in mind is that November is still hurricane season, so if a hurricane is nearby, SCUBA diving is impossible.

It is going to be as safe as any other time going SCUBA diving. One particular month does not make SCUBA diving dangerous. As long as your guide knows what their doing, you will be fine.

It's not recommended for a sport diver to go below 130 feet due to the partial pressure of oxygen being poisonous when it reaches the equivelant of 100% (5 atmospheres as there is about 20% oxygen in the air). Also the effect of Nitrogen narcosis can make your decision making erratic. It's not an exact science as to what depth an individual may succumb to this but 130 feet is a good guage of where you are relatively safe as long as you are obeying all the rules of training and you and your buddy are not irresponsible. Any deeper and you would need to mix gases and should get more specialised training.

just breathe normally through your mouth just keep your head down or it will fill with water! swim on the surface and when you lift you head out of the water makesure that your snorkel has not filled with water before you try to breathe through it again!! have fun ---- I like to "sip" the air over my tongue. It seems to trap droplettes moer effectively. Nice not to aspirate :} Actually, this answer is incorrect. When snorkelling, you take a deep breath, dive down and as u reach the surface u blast the water in the snorkel out and repeat the process. If you are jus swimming on the surface it is not technically snorkelling, but some people like to call it skin diving to clarify. Or -- as you ascend, you can point the snorkel straight back so it's entirely vertical and puff a little air into it at depth. As you ascend, the air in the snorkel will expand, forcing water out. Just as you hit the surface, vigorously rotate your head foprwards and downwards, so the snorkel moves roughly 1890 degrees and the opening is now in the air, nearly vertical. Blast a little air out to remove the tiny amount of water remaining. Also, I think the act of "snorkelling" refers to whatever you choose to do from the time you leave the boat until the time you leave the water. So this would include phases when you're breathing on the surface, diving to depth, holding your breath underwater, clearing your snorkel, etc.

Actually, 5 ATM can either be 132 feet or 165 feet. We all have 1 ATM above us (the air/sky/atmosphere) that creates a constant pressure.

Sooo.. 1 ATM + 4 ATM (33ft per ATM) = 132 feet underwater. However, if you actually mean 5 ATM UNDERWATER, then it would be 6 ATM (1 ATM + 5 ATM underwater) for the equation which would equal 165 feet.

Hope this helps!
