The Nauticam 70x300mm Carbon Fiber Aluminum Float Arm (SKU 72263) is a high-performance buoyancy accessory designed to offset the weight of heavy underwater camera housings, strobes, and video lights. Key Overview & Purpose SKU: 72263 Primary Function: Provides substantial positive buoyancy to neutralize or balance out heavy underwater rigs, reducing arm fatigue and making it easier to hold steady shots. Effective Buoyancy: 670g (approx. 1.48 lbs) of positive lift in water. Specifications Length: 300 mm (11.8 inches) Diameter: 70 mm (2.75 inches) Material Construction: Premium carbon fiber tubing paired with precision-machined aluminum ball ends and molded plastic caps. Depth Rating: 100 meters (330 feet) Key Benefits Zero Compression: Unlike traditional foam floats that compress under deep pressure (losing their buoyancy over time), Nauticam carbon fiber arms maintain their full lift capability even at 100 meters. Exceptional Strength & Rigidity: An internal aluminum spine ties the entire assembly together, making it structurally stronger than standard single-material arms while remaining significantly lighter than solid aluminum. Streamlined Profile: Offers a sleek, professional look compared to bulky foam blocks, minimizing water resistance when moving the rig. Accessory Compatibility: Can be paired with optional Nauticam bayonet holders (such as the Single Bayonet Holder for 70mm arms) to neatly stow wet-lenses like macro converters or focus optimizers directly on the arm when not in use.
