In night diving, lighting device is crucially important because of the challenging landform- Rugged reef, tunnels, and caves. Therefore visual feedback of the lighting device is of great concern for divers. However, normal flashlights only make sharp light-and-darkness contrast, which is less helpful for the observation of the landform. GRID flashlight projects grid-like light on the terrain, and turns it into a 3D-like scene.
The projected grid aids divers sense of perspective and therefore gives divers a much clearer picture of the landform.
