The Dot Line LED Level indicates level for either horizontal or vertical shots. The unit features a 3-position button for adjusting the brightness of the LEDs, enabling thus use in dark studios and bright sunlight.
The LEDs change from red to amber to green to indicate level. Also, on the side of the unit are additional LEDs that let you know if your camera is level from the position that you have the viewfinder in. Since these LEDs are on the side, you won't have to rise up over the camera to look.
The unit is equipped with a standard accessory foot by which it mounts a camera's hot shoe. Power is provided by an included CR2032 battery and can last up to 70 hours.
