Hey, i've just recently gotten into free-diving. After our last trip to Jamaica and Key West, i fell in love with it! i saw the coolest shell laying about 20 ft. down, but yet i didnt know anything about snorkeling underwater! I'm just starting the sport, and i was wondering if there is any equipment suggestions. I dont have the big bucks to spend, so nothing super pricy would work. I also live in Wisconsin..... but we own 3 lake cottages, so i do most my snorkeling there. I only get to the ocean for about 3-4 weeks of the year, but when i do i snorkel all day anyhow. So, some suggestions would be great
