•       Blast vision has been designed to work both indoor and outdoor, in a well-lit environment.  For the app to work correctly, you’ll need to have 6-10 feet of space between the mobile device camera and the ball / T. This will provide the camera with the best initial flight line view of the ball after impact. For optimal accuracy, the distance between the ball / T and the camera needs to be accurate when entered the app and it needs to remain constant while the app is being used.
