This is the third year I have used my Olympus Tough TD-820 camera. I put the camera on a small flexible tripod with a rock attached in the center (held in by elastics) which stabilizes the camera underwater while snorkeling. This also allows me to set the camera down on the bottom sand or on rocks. I do not put the camera on coral or sponges (I am a biologist and would not damage the environment). I also do not feed the fish to bring them close, since that changes the species distribution over time. When I float back to the surface, the fish are not bothered by the camera and will swim close to it. After a few minutes I dive back down and retrieve the camera and look for the next spot where fish are gathering. Sometimes I dive down and follow the fish, so the weighted tripod really helps to stabilize the camera while in motion. If snorkeling in Puerto Morelos, this is the only good spot to see a lot of fish and coral without paying $25 for a trip to the reef. The reef is very shallow (less than 8 feet), you must wear a life jacket and you get 45 minutes each at two different spots. I prefer to snorkel for several hours at a time and do not enjoy wearing a life jacket, so I prefer to snorkel from shore. I have snorkeled up and down the beach as far as you can go and still be in Puerto Morelos, and have found that there is only one good spot (shown in the video). It is an easy, less than 5 minute swim out to the rocks from shore. See my other videos where I identify the fish and also snorkel the reef. This movie was edited from a 1 hour version in Hi-Def. I hope you enjoy the video. I highly recommend the snorkeling spot shown here and a tour of the reef to fully appreciate the snorkeling that can be found here.
