I'm new to the sight. Well kind of. My husband and I took up scuba diving a year and half ago. He had no problems, where as I struggled. Because of this sight reading about others who had some of the same problems I have continued scuba diving. November we went to Chuuck lagoon and seen the World War II ship wreck. And now I'm rescue diver certified. I recommend the sight to others as well. Thank you for sharing
