Now that you are out diving, you will find that most of your dives will be from a boat, especially here in Florida. So, diving is diving, you say? True, but I am going to share a few little tidbits about how to enjoy your diving the most.
An interesting observation I frequently make is how few divers utilize redundant air supply systems. The redundant system I am referring to is a separate cylinder, regulator, and submersible pressure gauge (mini button type is fine.)
