Hi guys, thanks so much for your advice - much appreciated for the slightly anxious new diver that I am. I’ve got a question for you - snorkels: necessary or optional? My dive instructor didn’t have one when I was getting certified, he said he never used it.
I also have a new mask, and I know I have to clean it before first use - does this toothpaste business really work and if not, what should I be using? Also, how do I even know if I have successfully cleaned it?
