Kupo Big Boom 4-Way Geared Telescopic Boom Arm

The Kupo Big Boom is a heavy-duty telescopic boom arm designed for precise, controlled lighting placement in demanding studio or on-location setups. Its four-way geared control system—pan, tilt, rotation, and extension—allows you to position fixtures accurately without strain, even in awkward or hard-to-reach positions.

Built with a combination of steel and aluminium, the Big Boom balances strength with manageable handling. With a maximum extension of 3.63m (12’), it offers the reach needed for overhead lighting, while folding down to 2.25m for easier transport and storage. A dual receiver system (28mm junior and 16mm baby) ensures compatibility with a wide range of lighting fixtures, while the included saddlebag-style counterweight bag improves balance and stability during use.

Who this is for

• Studio photographers and cinematographers working with overhead or directional lighting
