Once you decide to move from the Scuba Diver Experience to the more fully certified Open Water certification, simply attend the two Class sessions conducted via ZOOM, complete 2 more ocean dives (for a total of 5) and pass the final exam. Your certification is issued for life and is internationally recognized. You will be able to dive anywhere on the planet in conditions similar to those you were trained in, or better.
When people say they are certified divers, this is what they mean. An instructor is no longer required for you to be able to dive in the ocean or large bodies of water. Remember, always dive with your buddy and never be afraid to ask an instructor for advice and opinions. As a certified diver, the final choice to dive is now yours. ENJOY!!
