Many snorkelers use a small personal floatation device called a snorkeling vest that can be inflated for personal flotation and safety. These vests come in many styles and provide some amount of flotation especially for those divers who are not totally comfortable in the water. The additional safety would be useful in water that has a current, or where waves or other kinds of water movement are present. A snorkeler who is carried away in a current may need to spend more time in the water than anticipated, so having a vest allows the diver to relax for a moment before swimming across the current to return to shore.
