pressurized yes, forced no. it is a demand reg only gives enough air to inhale, they will not pressurize your lungs, just like what firefighters use they will not explode your lungs

From the above, it really seems like you have a fundamental misunderstanding of how embolisms occur.
 
So what does a Spare air weigh and how much is it worth in gold? I know it will fluctuate with the price of gold but give me a ball park idea. I know my deco bottle is worth it's weight in gold, just ask me. :D

BTW, the worth of this thread...priceless!!
 
Bubblemaker Course Details
The PADI Bubblemaker program is for boys and girls age 8 and above. It’s fun, easy and safe. The PADI Bubble maker program is a way for youngsters to join in the family fun of scuba diving or even start a trend! Children should be OK in the water, but they don’t have to be super swimmers since the maximum depth is only 2m/6 ft.

For children eight years and older who want to have fun in the pool
Also available as an open water experience (two metre/six foot max. depth)
Conducted by PADI Instructors
No pre-training required
Uses equipment made for children – not adults
Typical sessions last about an hour (sign up, gear up and fun included)

8 year olds never go under water huh, isnt 6ft "under the water" Im glad you were not my instructor, you dont even know the courses.


This class is taught under the direct supervision of a Certified Instructor. A big difference.

rds912, I have a question for you. If I fill a balloon at the bottom of the pool 3 feet deep and fill it with 1 cubic foot of air and tie the balloon closed. And then I let the balloon go and it hits the surface, what will the volume of air be in the balloon when it reaches the surface?

I know! I bet there are a few on here that can answer that, but, I will bet a bunch have to go to their manuals or computer to find out the answer.

It amazes me the quality of training being dished out in the dive industry, just to make a dollar. Shameful!

In this sport, a lack of knowledge Kills!!!!!

I was kind of hoping rcs would answer without a bunch of hard comments. I am sure he loves his son very much and wants to share the things that are important to him with his son. He is spending time with his boy and that is to be much admired. I don't think he would knowingly bring any harm to his son.

So I think looking objectively at things will help him decide if this is a good practice going forward.

So the first thing is as the balloon goes up, how much does the volume change. It will change the same amount where it is in 3 feet of a pool, 3 feet of a lake, 3 feet of ocean.

I have some other questions, but one at a time.
 
rds912 ... the people here are not bashing you , they are trying to educate you on what it is that your doing, and the risk
... if you do not want to believe any of them, ask an instructor, if you don't want to believe an instructor, ask DAN, they have a diving medical hotline, are an authority on diving medicine, and could explain why your mistaken ... DAN Scuba Diving Medical Services
