Product Description

Upgrade your underwater photography with the buoyancy floating arm. Designed as an essential part of any scuba diving camera system, it serves as a light arm and balances the weight of your equipment underwater, reducing strain on your arms and wrists.

Superior Buoyancy: Our underwater buoyancy kits are engineered to provide high buoyancy, thanks to its high-density, high-hardness, and strong compressive strength properties. It can withstand up to 5 bars of water pressure, maintaining its shape at depths of up to 40m/131ft without deformation, and maximum depth 50m/164ft.
Lightweight and Stylish: The surface of the buoyancy floating arm is black, giving it a simple appearance with an inner diameter of 1 inch. It is compatible with various YS/double ball light arms and underwater tray on the market, including Seafrogs, nitescuba, Starbea strobe arms.
Versatile Solution: 1pcs of floating block provides -175g buoyancy, allowing you to add or remove floats to achieve the perfect amount of buoyancy for your camera system, depending on shooting style and conditions. The float black is more easy storage you can either put on your arm or store in air mesh bag.
More Efficient: More light weight and cheap compare to a traditional carbon float arm, 51g self-weight buoyancy block provides -175g buoyancy and you need a 155g carbon fiber float arm can provides 300g float. The float block will not flood and affordable.
Professional Support: Please feel free to contact us for any issues, a satisfied solution is promised forever. Made from premium polymeric materials, the buoyancy floating arm can withstand the harsh underwater environment, ensuring long-term use. Package includes: 4x buoyancy kits, 1x storage bag.

floating arm: outer diameter 8cm/3.2inch, thickness 3.8cm/1.5inch, inner diameter 2.5cm/1inch, provides 175g/6.2oz buoyancy.

To calculate the buoyancy needed for your camera system, determine the weight of your underwater set by using a hanging scale when it is submerged in water. Make sure to keep the scale above water as most models are not waterproof. Then, choose floating arms or floaters with sufficient positive floating capacity based on the weight of your set. Ensure that you have a balanced setup on both sides.
