When you’re scuba diving, you can get to lower depths than is possible with snorkelling. However every diver needs to know how deep they can go without posing a risk, particularly if you are beginner. Therefore you should always only dive within the limits of your training and experience. After you go below 6 metres, it becomes necessary to make decompression stops on the way up. However for those qualified and with plenty of experience you can try deep diving which usually begins at 18 metres. Depending on the experience you book, the instructor may set depth limits to ensure you can enjoy a safe scuba diving experience.
