** This products requires an Android (API 21 or newer) or iOS (version 10.0 or newer) compatible device which is not included with this purchase. A network is not needed to utilize the Dashr system, therefore a dedicated device can be purchased elsewhere for use with the Dashr timing systems. If multiple drills are run simultaneously, each drill requires it’s own mobile device to run the Dashr app.
