If ease of use and rapid adjustment are more important than rigid, heavy-duty support, the Bigblue Flexi system is the way to go.

How to Choose the Right Mount for Your Setup

Selecting a mount requires an honest assessment of the camera system and the typical dive environment. Larger housings with heavy strobes require rigid, ball-and-clamp systems, while lightweight video rigs are better served by flexible or minimalist mounts. Always consider the total weight of the rig; a setup that feels manageable on land will become significantly heavier and harder to stabilize after an hour in the water.

• Consider the Subject: Macro photography requires precision light positioning, favoring ball-and-clamp systems.
• Evaluate Portability: If travel is frequent, prioritize modular, lightweight mounts that can be easily dismantled.
• Check Compatibility: Ensure the mount is specifically threaded for the housing model to avoid unnecessary adapter stacks.
• Assess Durability: Materials like anodized aluminum resist corrosion better than plastic in harsh saltwater environments.

Ball Mounts vs. Flex Arms: Which is Better?

The debate between ball mounts and flex arms usually boils down to stability versus convenience. Ball mounts offer superior locking power and can support heavy strobes without sagging, which is essential for professional photography. Flex arms, conversely, allow for rapid, “on the fly” adjustments, making them a better choice for fast-moving subjects or video setups where lighting needs change constantly.

There is no single correct answer, as many divers actually use a hybrid approach. For example, a heavy strobe might be held by a rigid ball-and-clamp arm, while a small focus light uses a flex arm for quick repositioning. Understanding the specific lighting needs of the camera system is the only way to determine which style—or combination—will provide the best results.

Caring for Your Mounts: Post-Dive Maintenance

Saltwater is inherently corrosive, and gear failure almost always starts at the connection points of an underwater mount. After every dive, soak the entire assembly in fresh, warm water to dissolve crystallized salt that can seize up threads and locking hinges. Pay close attention to the springs and tension screws, as these are the first areas to show signs of oxidation or stiffness.

• Rinse Thoroughly: Freshwater immersion is non-negotiable after saltwater use.
• Lubricate Threads: Apply a light coat of silicone grease to metal screws to prevent permanent seizing.
• Check O-rings: If the mount uses movable joints, ensure internal seals remain clean and free of debris.
• Store Dry: Never store a wet rig in a closed case, as trapped moisture will accelerate corrosion rapidly.

Balancing Your Rig for Better Underwater Shots

A rig that is perfectly “neutral” in the water is the secret to steady, jitter-free footage and crisp photographs. If the rig is too buoyant, the diver will constantly fight to keep it submerged; if it is too heavy, it will cause exhaustion and shaky movements. Use float arms or buoyancy collars to counter the weight of heavy strobes and housing trays.

Achieving this balance allows the diver to manipulate the camera with only a few fingers, which is vital for delicate macro work. The goal is to create a rig that floats effortlessly in front of the diver, requiring minimal correction to stay level. Once the rig is balanced, the focus can shift entirely to composition, lighting, and the subject itself.

Properly outfitting an underwater housing is an investment in both the quality of the imagery and the ease of the diving experience. By choosing mounts that align with the specific needs of the camera and the diving environment, the process of documenting the underwater world becomes significantly more rewarding. Whether opting for the rock-solid stability of a ball-and-clamp system or the quick convenience of a flexible arm, a well-configured rig is the key to capturing the best possible footage.
