Use the camera or a PC to create written or voice memos that can later be added to photos. Memos can contain up to 30 seconds of audio or up to 100 items with descriptions of up to 128 characters each. A previously-recorded image of a survey slate can be embedded as sub-image to a photo of the entire worksite, making it easier to take photos when your hands are too full, or the location too cramped or too dark, to place a slate. You can also choose the slate's size (large, medium, or small) and location (up, down, left, or right). The lens is surrounded by a six-LED ring light. You can choose which LEDs light and adjust their brightness to get clear shots showing fine details such as the model numbers on small parts or scratches in walls or floors. Shoot movies in 4K for high-resolution footage that gives you an overall view of a big construction site, for example, or helps you grasp the relative positions of various objects.
