Had he monitored his air supply better, he could have made a slow, safe ascent to the surface by following the bottom contours and swam right up to the beach. Too late, he realized he hadn’t brought along a glow stick to attach to his tank valve. So, when none of his friends wanted to join him for a night dive, he decided he would go anyway. The force of the blow pushed him aside and back under the water. Check out the video below to see what night diving with Mantas is all about. To maintain your orientation and safety, I advise you to choose a shallow and relatively easy dive site to explore at night. One of the neat things you will experience on a night dive is the phosphorescence appearance of bio-luminescence plankton. On a night dive, your senses are acuter, and you are more aware of your surroundings. Instead of the light beam being filtered by 30 feet of water it is only being filtered by a few feet. He realized that simply following his own dive light made him slow down and pay more attention, rather than trying to cover as much distance as possible on the dive. Scuba diving is not dangerous as long as a diver seeks thorough training, follows safe diving guidelines, uses proper gear, and dives within his experience level. There is a saying about opera when people see an opera the first time it is very dramatic; you either love it, or you hate it. He told himself he would stay close to the beach just down from their campsite. They were moving as fast as they could justify, keeping their own safety in mind. Sean’s dive took him well away from the beach, more than 200 yards out. The intermittent clouds took away any chance of Sean being seen. He planned to stay shallow and close to the beach, but he failed to monitor his own depth, time and air consumption. In either case plenty of certified divers no longer (or never did) understand how a buoyancy compensator (BC) works or how pressure changes on descent and ascent affect buoyancy. When you wave your arms underwater at night, the bioluminescent plankton will react by creating a light, and it looks like your arms are decorated like a Christmas tree. At night the coral polyps open to feed, drawing nutrients from the passing currents. Splash into Cozumel’s legendary undersea world, teeming with life and featuring nearly unlimited visibility! And then he heard the boat motor. If the water is so rough that water movement is going to be an issue, don't dive or end a dive the moment the difficult current/surge/chop is experienced. As you start your night dive, you may wonder what you are getting yourself into. For example, most open water certifications qualify a diver to go down to 60 feet, no deeper. The not-so-fatal lionfish can leave a painful sting – Credit: Joshua Haviv. If this subject is unclear, or if a diver simply hasn't developed the physical ability to control his buoyancy properly, he needs practice and a scuba diving refresher course before attempting to dive again. If a buddy constantly strays so far that he is impossible to alert in an out-of-air emergency, get a new buddy. You will carry a primary dive light which usually is a wide beam torch. Do you believe that there is a huge monster lurking in the deep? He felt he knew it like the back of his hand. Reproduction in whole or in part without permission is prohibited. As you start your night dive, you may wonder what you are getting yourself into. Communication between divers in the dark is difficult, and the system of communication to be followed in the water should be clearly understood before anyone enters the water. He also didn’t think to take a float or a dive flag with him. He was new to diving and lacked even the basic safety equipment. If a primary dive light fails, you can turn on the secondary light, and you and your buddy can safely abort the dive. They had no idea that anyone else was even in the water. The top three root causes leading to diver fatalities (DAN Diving Fatalities Workshop Report) are: All three of these are completely avoidable. Video can bring non-divers into the underwater action. Humans are not built to breathe underwater, which means that a diver is completely dependent upon the proper equipment, skills, and emergency training to ensure a safe resurface for every dive. He’d made only one night dive in his life, and he had been accompanied by his instructor. Divers who treat their scuba training as a "do it once and be done" course and fail to review dive theory and practice basic scuba skills after periods of diving inactivity (and I mean after a short period of diving inactivity, such as 6 months) are more at risk of a diving injury that divers who keep their skills current. As you swim towards the reef, you will try to pick out landmarks that you saw earlier. In other words, be gentle, careful, and respectful, and don’t harass the marine life you encounter during a night dive. Save my name, email, and website in this browser for the next time I comment. It will show you a different place, one with more color and maybe even more species of marine life and more action than you ever saw on your favorite reef. Sean’s all black dive gear, including his tank, blended in with the water’s surface. All rights reserved. He wanted to travel the world, and he told all his friends he was going to be the next Jacques Cousteau. As the plankton touches something, such as your arm, it will glow similar as a Firefly but by a different process. According to the "Diver's Alert Network (DAN) 2010 Diving Fatalities Workshop Report", a diving fatality occurs in 1 out of every 211,864 dives. Sean wanted to become a technical diver to explore caves and deep wrecks, but he barely had 20 dives under his belt. He found himself noticing details that he hadn’t seen before, even in places he recalled from earlier in the day. Just 24 years old, he had never had much direction in his life, but suddenly his head was full of ideas of adventure.
