With it is 50 mm height and 280 mm x 230 mm dimensions this buoyancy foam is engineered in order to support up to 120 meter depth. It provides buoyancy at every depth by maintaining its volume and can carry up to 5.2 kg of load.
The surface of the foam is coated so that it can perform in freshwater or saltwater. Coating makes the foam strong with high impact resistance. It is solvent and grease resistant, painted yellow to make it visible for underwater applications. It has two 70 mm diameter holes to allow some space for vertical thrusters.
