Dive Snorkeling Why can you go deeper underwater while Scuba Diving than snorkeling? Physics?
Please help explain (in terms of physics i.e water pressure, atmospheric pressure, etc) why you can go deeper underwater while scuba diving than you can while snorkeling. Thanks!
It has nothing to do with Physics, it all pertains to how long you can hold your breath.
Check out free dive competitions, people have gone as far as 400 ft before.
Now if you are Scuba Diving you have a limited amount of time at certain depths before it becomes dangerous dude to the nitrogen build up that occurs in your blood. The Nitrogen molecules expand when you go back to the surface to the atmospheric pressure increase and decrease.

Either tank will do fine. The 80 / 3000 tank is the smallest tank that I would get for paintball. Your first fill will give you 3000 psi. After that the psi falls. Once you get to less then 2000 psi, it’s nearly useless. If you are getting this for the use of one or two players, it should last you a days play fine. If you are going to support more players you may run short.
Used tanks are not a bad way to go. But check the hydro life on them. New tanks have 7 years of hydro with a yearly visual inspection needed . If the used tank only has 3 years left on it, get the new one.
It’s about twice the cost, however, a steel 120 high pressure (3450 psi) is the best tank for paintball. Assuming your markers tank is 3000, then you will get 3 to 5 completely full tanks before the psi of the scuba tank drops below 3000. Just be sure not to over fill your marker tank.

Scuba Diving for Beginners : Basic Gear for Scuba Diving
Computer Scuba Do you know of a scuba Dive Computer with these features?
I am looking to purchase my first dive computer and I am having a little trouble sorting through the seemingly endless assortment that is available. I am looking for one that has the ability to be hooked up to my computer (mac compatible) and upload all the information about depth, air consumption, time, etc to something like an electronic log book so I can save all the information from my dives. If possible I would like it to have a program with it for me to enter in information about the dives it uploads information about like location, what I saw, etc.
Thanks for any info!
There are a few options. The first thing that you will find is computers are priced all over the place. For ones that have the features you are looking for, you will be paying a bit more. The main reason is you will need one with "Air Intergration" in order to do anything with air consumtion. ---- But these can sometimes be very handy underwater as well. Most can on the fly calculate how many minutes of gas / safe time is left in your tank. There are 2 types of air intergrated computers. Wireless and regular. The regular will have a hose and will replace your spg. The wireless kind will have a knob sized transmitter that screws into a high pressure port. (where your spg is now) and transmit to a wrist mounted computer. This kind is more expensive than the regular.
The other thing is whether or not you are nitrox certified today, i'd recommend getting a nitrox computer. They can do air or nitrox / so if you decide to go nitrox later you will have the right equip.
If you are looking for a good AI (air intergrated) computer, the Sherwood Wisdom II is a very good computer. Aris and Scuba Pro make decent wireless computers.
Look online as well as your LDS for computers because the prices on the same model could be very different.

James Bond's fourth adventure takes him to the Bahamas, where a NATO warplane with a nuclear payload has disappeared into the sea. Bond (Sean Connery) travels from a tiny health spa (where he tangles with a mechanized masseuse run amuck) to the casinos of Nassau and soon picks up the trail of SPECTRE's number-two man, Emilio Largo (Adolfo Celi), and his beautiful mistress, Domino (Claudine Auger),...
After years of enduring Roger Moore in the role of James Bond, it was good to have Sean Connery back in this 1983 film for a one-time-only trip down 007's memory lane. Connery's Bond, a bit of a dinosaur in the British secret service at (then) 52, is still in demand during times of crisis. Sadly, the film is not very good. In this rehash of Thunderball, Bond is pitted against a worthy underwater v...

Down Scuba I am enrolled in this Scuba Diving class and I am a good swimmer I swim 50 laps a day;however, I am still a?
little fearful of diving class. I haven't ever attended any diving class yet I am fixing to. I dive down to the bottom of the pool when I am swimming without gear and that is a 16ft. pool. Why am I a little fearful and is this normal?
Being a little anxious or nervous is normal before the class. It is a completely new activity that just isn't "normal". Here are my tips:
1. Pay attention.
2. Ask questions. There are three types of questions:
--You think it is stupid, but you know what, five other people in the class are thinking the exact same thing. Ask it.
--You actually answer your own question while asking it, but you know what, five other people in the class are thinking the exact same thing. Ask it.
--Something you don't understand. Ask it.
3. Slow and steady. Nothing in scuba diving is fast.
In 1949 Denzel James Dockery used the "Baker" flag (a solid red DANGER flag) when diving as he had used it in the Navy, but the flag was not recognized by civilian marine operators. He fabricated a red flag with a white stripe running across the middle, but discovered that this flag was a copy of a National Flag used by Austria. After much research the White Stripe was moved to ren from the uppe...
