Patent attributes
A system for indicating an energy transfer level having an optical sighting system and a mobile application running on a mobile device. The optical sighting system has an electronic, non-numeric performance indicator structured to provide a notification signal to a user. The mobile application is configured to receive a user input indicative of a desired terminal performance value for a projectile. The optical lighting system is configured to activate, when a predicted terminal performance value does not exceed the desired terminal performance value, an electronic, non-numeric performance indicator structured to provide a notification signal to a user. The electronic, non-numeric performance indicator may be an intermittently-displayed hold-over point indicator.
