With the ATN Ballistic Calculator, you can forget about charts and complex reticles. Just enter the environmental data and all the calculations will automatically be performed. This provides you with the opportunity to hit your target, even on the first attempt. By incorporating a Dual Core Processor, the X-Sight 4K Pro Series is able to provide a much more enhanced experience. You can live stream via WiFi to a mobile device, and record in your scope at the same time without lag or loss of performance.
