Sealife Flex Arm SL9901 adjustable-length lightweight arm for underwater lighting

The Sealife Flex Arm SL9901 is a lightweight, adjustable-length arm designed to support underwater lighting and camera accessories. Constructed for durability in corrosive environments, it enables precise positioning of lights or strobes on dive rigs and housings. The arm’s flexibility and secure joints provide stable support while allowing rapid adjustments to framing and illumination during dives. Its compact folded profile and modest weight make it suitable for both travel and extended underwater sessions.

Advantages

The adjustable-length mechanism offers a wide range of reach without adding significant bulk, while corrosion-resistant materials ensure long-term performance in saltwater conditions. The lightweight construction minimizes added torque on housings and trays, and the locking joints maintain chosen positions under typical underwater loads. The arm is compatible with common accessory mounts used in underwater photography and videography setups, simplifying integration with existing gear.

Suitable for

• Positioning LED lights or strobes for macro and wide-angle underwater photography
• Mounting small video lights to achieve controlled illumination while diving
• Adjustable support for dual-light configurations on dive housings and trays
• Use on travel rigs where compact, lightweight components are required

Key specifications

• Adjustable length range to allow variable reach and positioning
• Lightweight construction to reduce strain on cameras and trays
• Corrosion-resistant materials suitable for saltwater use
• Secure locking joints to maintain position under typical underwater loads
• Compact folded profile for convenient storage and transport

How to use

Attach the flex arm to the accessory mount on your housing or tray using the compatible mounting point. Secure the light or strobe to the other end of the arm and tighten the locking joints to a firm but not over-tightened setting. Adjust the arm’s length and angle to achieve the desired framing and illumination; make fine position changes by loosening a joint slightly, moving the arm, then re-locking. After use, rinse the arm thoroughly with fresh water to remove salt and debris, then allow it to dry before storage.

Usage recommendations

For consistent performance, periodically inspect joints and mounting points for wear, tighten fasteners to recommended torque without over-tightening, and rinse with fresh water after each saltwater dive. Use the arm within its intended load capacity and avoid sudden impacts or heavy side loads that could deform components.
