The real-time heads-up display helps you learn more about how you cant your rifle when you shoot, how barrel temperature affects your shots, and shows quick-access weather information. All of this information is automatically logged to your account when shots take place. Reactor NEVER logs this information without your Fusion Module being on and paired, and we have completely transparent business practices to ensure your privacy and rights as a gun owner are protected.
