An invisible infrared flash provides clear, detailed, high-resolution nighttime images,without the game-spooking effects of a standard white flash. The flash provides a full 45 ft. of illumination. Each image is automatically stamped with the time, date, temperature and moon phase so you can maintain accurate scouting reports. Three settings let you determine image resolution. With 32MB of internal memory, it will hold an assortment of images. For additional storage, the Game Spy 4.0 IR also will accept up to a 4GB SD card (sold separately). Laser Aim allows you to monitor and test the targeted picture area to ensure your camera is taking pictures of the exact area you are scouting. Six D- batteries provide up to 150 days of battery life (not included). Compatible with Moultrie Game Camera Power Pack (sold below). Auto flash turns off in bright sunlight and automatically activates in low light or after dark. Other features include upgradeable software and a one-second delay.
