High Buoyancy EVA Aluminum Arm
The BigBlue Buoyancy Arm combines a unique shape and structural design with the best selection of materials, to achieve high buoyancy with an extremely low carrying weight. Even after multiple use at great depth for prolonged periods of time, the shape and buoyancy of the float remains almost unchanged.
- The high buoyancy and low carrying weight of the EVA foamed material, provides effective buoyancy compensation for the weighty load of photographic or video system.
- The unique shape produces a low drag and easily folds up even with the jumbo size float.
- The buoyancy arms are designed to go with or without the float. By simply unscrewing the bolt at the ball joint, you can easily dismount the float.
- The triangular design of the aluminum arm utilizes a super lightweight yet ultra strong structure, making it one of the lightest among all aluminum arms.
- The ball head of the arm is molded from fiberglass reinforced resin, which is feather light in weight, yet sound and sturdy in structure. Combined with its highly abrasive resistant nature, it is ideal in providing a strong and supportive hold to your heavy equipment.
