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.
A water belt tied around the swimmer's waist helps them stay afloat and upright. However, the water belt does not have the support of a lifejacket , so an unskilled swimmer needs supervision. In addition to the water belt, swimmers can wear ankle support, water gloves on their hands and water shoes on their feet.

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 water bottle pocket folds out from a hidden compartment in the back and is the perfect size for an average plastic water bottle (16.9 fl oz), so if you love to stomp around town with a giant ...
Weight belts are the most common weighting system currently in use for recreational diving. [17] Weight belts are often made of tough nylon webbing, but other materials such as rubber can be used. Weight belts for scuba and breathhold diving are generally fitted with a quick release buckle to allow the dumping of weight rapidly in an emergency. [7]
Diving equipment, or underwater diving equipment, is equipment used by underwater divers to make diving activities possible, easier, safer and/or more comfortable. This may be equipment primarily intended for this purpose, or equipment intended for other purposes which is found to be suitable for diving use.
The divers inflate their buoyancy compensators attached to their diving cylinders and put them into the water to float while remaining tethered to the boat. Then they put on their masks, fins, and weight belts, slide overboard, [clarification needed] and put on their scuba sets while floating. Once the divers are ready, they descend and proceed ...
A pony bottle is commonly used as a bailout bottle, but this would depend on the time required to surface. Divers doing technical diving often carry different gases, each in a separate cylinder, for each phase of the dive: [60] travel gas is used during the descent and ascent. It is typically air or nitrox with an oxygen content between 21% and ...
