The tray applied under the housing is an essential component for optimizing underwater equipment's balance and improving its stability on a plane in the air. This system allows the position of the sliding pads to be adjusted forward or backward, adapting the balance according to the photographer's specific needs or the type of configuration used. The use of floats or weights facilitates the process. Adjusting the balance prevents the housing from tilting forward or backward, improving overall handling and reducing the diver's effort. Moreover, a well-balanced housing makes shooting operations underwater easier, allowing for more stable images and smoother movements.
