The Nauticam Carbon Fiber Aluminum Buoyancy Arm Series is made from a high quality carbon fiber tube with molded plastic end caps and machined aluminum balls. Each arm includes an aluminum backer that connects the entire assembly together, making the arm stronger than one made from solid aluminum alone. This sturdy construction allows these arms to be waterproof for a long time!
Nauticam Carbon Fiber Buoyancy Arm System
One approach that some underwater photographers have taken to reduce downforce is to use buoyancy arms made of a special type of foam that compresses less than conventional foam. While this can be a useful option, foam has its drawbacks. Typical "incompressible" foam bladders begin to compress noticeably at 30 m diving depth and by 60 m have lost völl effectiveness and begin to deform permanently. Foam can also degrade over time. Nauticam carbon fiber arms do not compress measurably, even at 100 meters, and appear more streamlined than chunky foam bladders.
Carbon fiber doesn't just look cool, though. It is five times as strong as steel, yet weighs about two-thirds less. Lighter means more net lift for the same volume. In the 60 mm diameter class, for example, the Nauticam arm offers 50% more buoyancy than other competing aluminum tube arms. The 90 mm diameter arms are perfect for systems that require even more buoyancy.
The Nauticam system of arms, clamps, trays and other mounting hardware offers a variety of lighting arrangement options. The additional carbon fiber arms allow the underwater shooter even more flexibility in dialing in the rig he or she wants.
