Weefine WFA37 Adjustable Float Arm

Weefine Adjustable Float Arm - WFA37

The Weefine WFA37 Adjustable Float Arm is engineered to provide controlled buoyancy adjustment for underwater photographers and videographers who demand precise rig balance.

With a maximum positive buoyancy of +520g, the WFA37 allows you to offset heavy housings, dual strobes, or powerful video lights, helping achieve near-neutral trim in the water. Proper buoyancy significantly improves stability, reduces wrist and arm fatigue, and makes fine macro adjustments or smooth video pans far easier.

Unlike fixed float arms, the WFA37 features an adjustable internal air chamber, allowing you to fine-tune lift depending on your configuration. Whether you are shooting macro with strobes or wide-angle video with constant lighting, you can dial in the right amount of flotation for your setup.

Why +520g Matters

For many mirrorless and DSLR systems running dual strobes, +520g of lift is often the sweet spot — enough to offset arm and lighting weight without making the rig excessively positive. This gives you:

• Improved underwater trim
• Reduced diver fatigue on long dives
• Greater stability for macro precision
• Smoother video movement
• Better overall handling and control

The WFA37 integrates seamlessly into standard 1-inch ball mount systems and is compatible with most clamps, arms, strobes and video lights. Built from corrosion-resistant materials, it is designed to withstand demanding saltwater use while maintaining structural integrity and professional performance.
