Float arm 20 x 5 cm (150 g buoyancy)

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. This robust design is why we are able to guarantee these arms' watertightness for life! Carbon fiber doesn't just look cool. It is five times as strong as steel, yet weighs about two-thirds less. Lighter weight means more net buoyancy for the same volume.  NAUTICAM CARBON FIBER FLOAT ARM SYSTEM One approach that some underwater photographers have taken to lighten the load underwater is through the use of floats made of a special type of foam that compresses less than conventional foam. While this can be a useful option, foam does have its drawbacks. Typical "incompressible" foam blocks begin to noticeably compress at 100' and by 200' have completely lost effectiveness, and have begun to permanently deform. Foam can also break down over time and make something of a mess. 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 weight means more net buoyancy for the same volume.  The Nauticam system of arms, clamps, trays and other mounting hardware allows a huge range of possibilities for arranging lighting.  DIALING IN YOUR BUOYANCY With a variety of lengths and widths, the Nauticam carbon fiber float arm system lets you dial in the buoyancy you want.  Each arm has a clearly rated net buoyancy (lift) and with the wide selection of attachment options, it's finally possible to get your rig perfectly balanced for your shooting style.   

Tube of 50mm diameter with 25mm balls.

Great buoyancy The Float Arm uses weather-resistant ABS material for its component arm body to lighten total weight creating extraordinary buoyancy comparing to existing solid arm type float system together with its hollow arm body design. The hollow arm body enables not only helping weight trimming but also provide extra buoyancy. Wide variety of Float Arm Float Arm system have line-up total 5 different type; [Float Arm] of standard φ50mm / 2in with three different length and [Mega Float Arm] of 95mm / 3.8in with two different length. New INON Float Arm system including existing [Arm Float S]provides perfect solution to benefit desired underwater weight of your camera system depending on shooting style, conditions. Secure and stable gripping The Float Arm is fully compatible with existing INON Arm II system with its high-precision machined aluminum alloy ball joint providing perfect balance between stable clamping and stress-free handling thanks to ozone-proof and weather-proof silicon rubber O-ring. Your INON Arm II system is fully compatible with new Float Arm. Inon float arm with attachment lens holder (optional) Inon float arm with hot shoe mount (optional)
