The Magnetic Defect Scale-Bar is an essential tool designed for underwater inspection by divers, primarily used to photograph and measure defects on subsea structures. It features a bright yellow, easy-to-read linear scale marked from 0 to 15 units, ensuring clear visibility against underwater environments. The scale-bar is equipped with high-strength magnets, which allow for secure and stable attachment to metal subsea structures, facilitating hands-free operation and ensuring precise measurements. The robust construction of the scale-bar ensures durability and reliable performance in the challenging underwater conditions encountered during offshore inspections. The compact and user-friendly design of this tool, combined with its high-visibility scale and powerful magnetic adhesion, makes it an invaluable asset for accurate documentation and assessment of the integrity of subsea installations.
