I think Scuba-diving is such a cool activity. Not only do you look so high-tech with all your gear on, but there's an element of danger that you don't get from most activities.
Great informative post and I love your subtle humor that is sprinkled throughout you post! - The SPG or the submersible pressure gauge tells you how much air is left in your tank. Apparently, it is very important to know that while you are scuba diving.

I'm so happy you noticed that. 😊
Thanks for reading!
