The M6 or 1/4" ball head adapter is a modular connection point for underwater accessories such as buoyancy arms, video lights or action cameras. With its universal threaded connection (M6 or 1/4"), it can be flexibly mounted on common underwater housings, especially on the DIVEVOLK Expansion Clamp. The system makes it easy to expand the equipment with additional components. Made of aluminum alloy with stainless steel screws, the adapter provides a stable, corrosion-resistant connection while remaining lightweight.
