Nauticam 70x300mm Carbon Fibre Aluminium Float Arm (+670g)

The Nauticam Carbon Fiber Float Arms series are manufactured from a high quality carbon fiber tubing with molded plastic end caps and machined aluminum balls. O-Ring seals ensure water tight integrity and each arm includes an aluminum spine that ties the entire assembly together, making the arm stronger than one machined from solid aluminum alone. Nauticam Carbon Fiber arms do not measurably compress even at 100 meters/330 feet, and look more streamlined than chunky foam blocks. 

Carbon fiber doesn't just look cool. It is five times as strong as steel, yet weighs about two-thirds less. Lighter means more net buoyancy for the same volume. In the 60mm diameter class, for example, the Nauticam arm provides 50% more buoyancy than competitors aluminum tubing arms. The 90mm diameter arms are perfect for systems demanding even more lift.
