This professional underwater photography bundle merges the precision of a CNC aluminum butterfly clamp with two heavy-duty 1/4"-20 ball head adapters, engineered for creators demanding modular control beneath the waves. The clamp's 1-inch jaw secures flashlight brackets to underwater drone arms, while the dual black ball heads rotate 360° to position GoPro MAX housings for 8K VR capture or angle video lights across shipwreck exploration scenes. Hard-anodized surfaces withstand hydrothermal vent filming pressures, and the wing nut's ergonomic ridges provide tactile feedback when adjusting equipment mid-dive. Ideal for synchronizing multiple Sony A7S III cameras on submarine ROVs or mounting Lume Cube panels to rebreather harnesses during night dives.
