Expand your photographic reach with a dual-ball buoyant extension rod. Made from lightweight yet robust carbon fiber and aluminum alloy, it provides strong support for extending the reach of action cameras and lighting setups. Eight length options from 12.7 cm to 30.5 cm between the ball heads offer precise control for your conditions and style. Available lengths (between ball heads): 12.7, 15.2, 17.8, 20.3, 22.9, 25.4, 27.9, 30.5 cm. Compatibility is ensured by the standard 2.5 cm ball head design, allowing easy mounting with a wide range of photo accessories. This enhances your creative potential in both underwater and terrestrial photography. Suitable for all photo enthusiasts: ideal for amateur and professional photographers who want to improve underwater photography or gain extra reach on dry land. Use scenarios: - Underwater lighting: position lights at a distance from the camera for even, shadow-free illumination of macro subjects. - Above water or side lighting: extend reach for landscapes, portraits, or product shots where closer proximity is not possible. - Tight spaces or overhead shots: gain access to hard-to-reach angles without compromising stability or buoyancy.
