LONGSHOT&';s wireless, portable, and battery-powered target camera systems are set up adjacent to your target and 10-15 ft. back; the long-distance wireless camera can be moved within that range to adjust the field of view. Since the long-range wireless camera is positioned downrange by the target, you&';ll never have to worry about fighting mirage to see your shots again. With a runtime of 9+ hours, LONGSHOT LR-3 cameras allow you to view the target remotely on your tablet or phone via an easy-to-use free Longshotapp (track and number shots, save photos, review sessions, record video, and stills). No cell or WiFi service is required. You&';ll have live HD video at your fingertips, making it easy to see where your shots are hitting seeing your shot has never been easier.
