Many improvements have been made to insure that you have a quality product that will last you many years. The 35 mm camera that comes with your unit is a Foresite branded camera made for Buckshot35. When used in the Buckshot35 housing no AA batteries are required in the camera.
Power is supplied by the D cell battery pack in the housing.
Two AA batteries are required in the camera only if it is used separate from the Buckshot35 system. Useful information on film loading and rewinding is included with the instructions that come with the camera. Although the detector does not actually emit a beam, it has a detection area similar to a flashlight beam. Near the unit, the beam is only a couple of inches in diameter. At 10 feet, the diameter is 1 ft.
