A good tray and arm system is often overlooked when building up an underwater camera set-up. A sturdy tray is not only for attaching lights on to your system but also for enhanced image stability. A clever underwater photographer also uses their arm system for buoyancy control by adding arm sections that provide lift underwater for their otherwise heavy photographic equipment. Underwater camera trays and arm come in all shapes and styles and not everything will fit everything else. If you are unsure what kind of arm system is best for you don't hesitate to contact us. We'd be happy to advise you on this.
