Can I fill a scuba tank with an air compressor?
Scuba tanks typically need to be filled at very high pressure (about 3,000 psi). Using a regular air compressor would only be able to provide a fraction of the air that scuba compressors can. Secondly, the scuba compressors have filters that are designed to purify the air that goes through them and fills the tank.
Is it illegal to scuba dive without certification?

How long can a scuba diver stay at 100 feet?
Nitrogen is absorbed more readily at deeper depths, making how long can you SCUBA dive dependent on how deep you are. For instance, the time you can spend SCUBA diving at 100 feet is 20 minutes whereas if you limit your dive depth to 35 feet, you could stay for 205 minutes (if you had enough air).

What size scuba tank should I buy?
Most recreational divers find a common aluminum 80 to 100-cubic-foot tank is sufficient for their needs. An aluminum 63 cft may be a better fit for a younger and shorter diver while still providing enough gas for their needs. Larger divers tend to have greater gas consumption rates in direct proportion to their size.
