I am new to snorkeling and have questions. I have a snorkeling excursion planned in April in Biscayne National Park. One of the sites I will be snorkeling to is Brewster Reef. The site is 25 feet deep. Can you safely snorkel to that depth especially since I’m new and would snorkeling at that depth easy to do. I bought shorts fins because I’m traveling but do I need longer ones. I also have a GoPro 12 with underwater housing and bought the polar pro filter kit from GoPro. If the sites depth is 25 and Google says the average snorkeling depth is 12-15 but 25 feet is possible. Would I just go to down halfway to get a better look like 12-15 and would that give enough detail and would using the snorkel filter that is rated 12-15 be good to capture the colors of Brewster Reef. Also if snorkeling to 25 feet is attainable or easy to do I assume moving to the red filter would the correct filter. I also want to note that I am taking a snorkeling class before I go. Thank you for any advice you can give and your thoughts.
