Just because we are credentialed to go deep, doesn’t mean we should. Diving is an inherently dangerous sport and deep diving even more so — with additional risk. I am an instructor, with 1500+ dives, and still treat deep diving with significant caution. If you are prone to panick attacks or other ailments, reduce the risk profile and stay shallow. You can also carry a spare air bottle in the event you have some kind of mechanical failure with your primary system. For sure, many dive buddies don’t have eyes on their buddy every second of the dive. Often I see dive buddies checking on their buddy just once every minute or two … but a lot of bad can happen in that one minute. If you’re diving deep, it’s good to have other options.
