- Carbon fiber construction: Made from high-quality carbon fiber and aluminum alloy, this buoyancy extension rod combines exceptional strength with light weight. The rugged material provides stability during underwater photography, helping you capture stunning images without device concerns. - Available in three sizes: 12.7 cm, 20.3 cm, or 25.4 cm length to fit your underwater photography needs. Each size delivers optimal extension while maintaining the balance of your camera setup, offering flexibility for different environments. - Precise buoyancy control: Each rod has clearly marked buoyancy data to help you achieve neutral buoyancy with your underwater camera rig. This calculated buoyancy reduces arm fatigue on longer dives and supports stable, pro quality shots. - Standard 2.5 cm ball heads: Equipped with two standard 2.5 cm ball heads compatible with a range of underwater photography devices. The versatile mounting points enable multiple configurations and adjustable angles, giving you full creative control over your underwater shots. - Use scenario: Ideal for reef macro work where close subjects require a compact, balanced extension (choose 12.7 cm for tight spaces). - Use scenario: In wrecks or kelp forests, opt for 20.3 cm or 25.4 cm to gain reach while preserving flexible aiming and mounting options. - Use scenario: During long dives or video work, neutral buoyancy and stable framing reduce arm fatigue and help maintain consistent, professional results.
