Some buoyancy aids may not provide the same high level of protection as lifejackets. Canoeing and kayaking buoyancy aids are designed with mobility in mind. A buoyancy aid that does not fit properly can restrict a paddler's (kayaker's) range of movement, which could cause them to tire or prevent them from paddling properly.
Personal flotation devices being worn on a navy transport . A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water.
The buoyancy compensator is used by ambient pressure divers using underwater breathing apparatus to adjust buoyancy underwater or at the surface within the range of slightly negative to slightly positive, to allow neutral buoyancy to be maintained throughout the depth range of the planned dive, and to compensate for changes in weight due to breathing gas consumption during the dive.
National safety standards such as BS EN 13138-3:2007 in the United Kingdom require inflatable armbands to conform to certain standards, like puncture resistance and the level of buoyancy retained after a period of time beyond the inflation valve being opened and left open. This is an assessment of the efficiency of non-return valves designed to ...
Buoyancy control is considered both an essential skill and one of the most difficult for the novice to master. Lack of proper buoyancy control increases the risk of disturbing or damaging the surroundings, and is a source of additional and unnecessary physical effort to maintain precise depth, which also increases stress.
A lifebuoy or life ring, among many other names (see § Other names), is a life-saving buoy designed to be thrown to a person in water to provide buoyancy and prevent drowning. [1] Some modern lifebuoys are fitted with one or more seawater-activated lights to aid rescue at night.

It is also referred to as a torpedo buoy (often called a "torp") because of its shape. Because of its rigidity, it is slightly more hazardous in surf conditions. However, the rescue buoy generally has more buoyancy than a rescue tube, allowing the rescuer to assist multiple victims There are several colors and sizes available commercially.
