Your dog will have a lot of fun playing fetch with the automatic ball launcher. The waterproof ball launcher is perfect for interactive play both indoors and outdoors. With 9 different distance settings and 6 angle settings, the launcher throws standard-sized tennis balls from distances of 2.5 to 9 meters at angles of up to 45 degrees. Multiple built-in safety sensors ensure the safety of pets and people while playing, and the automatic sleep mode ensures that your dog doesn't overexert itself. It can hold up to 3 standard-sized tennis balls (2 tennis balls are included). The launcher emits a sound signal before a ball is thrown. The handle is comfortable.
