A certification is achieved after you pass all of the requirements during your scuba diving program. The best way to learn to scuba dive is to earn your Open Water Diver certification, which will certify you to dive safely to a maximum of 18 meters (60 feet) deep.
Once you have this certification, you can flash it at any dive center around the world and start exploring the incredible underwater world. But getting your Open Water Diver certification is just the start of the adventure! There are many advanced diver programs you can join that will certify you to dive deeper, go shipwreck diving, try night diving, and more.
