It is not illegal to dive without certification, but no reputable dive center or club would allow someone to dive with them without first being certified to scuba dive.
How far can you scuba dive without certification?
The short, super long answer is as an Open Water certified diver you are qualified to dive independently (with a buddy of course), without a certified professional guiding you, to 18m/60ft. This is why we recommend continuing your scuba education and going on more dives.
Do you have to be certified to buy scuba gear?
First of all you will need to complete a PADI scuba diving certification course, which is accredited around the world. Without this certification you cannot access any diving facility, buy any scuba diving gear and will be refused if you try to fill up your tank.
Can you breathe through your nose when scuba diving?
You cant breathe through your nose. Many beginner divers experience discomfort because they need to breathe entirely through their mouths, furthermore, do it while biting down on the regulator mouthpiece.
Can a human survive 47 meters underwater?
According to the US Navy dive decompression tables a diver may spend up to five minutes at 160 (47 meters) without needing to decompress during their ascent. It would actually take more than four hours to safely surface from a 60-minute dive at a depth of 160 feet.
