All Frontier models feature Hawke's new H7 optics, offering stunning high definition viewing with incredible colour control and phase correction. The Hawke Frontier LRF binoculars use high light transmission optics and a red coloured OLED display to make the view to your target clearer than ever before. Frontier LRF Binoculars are designed to deliver highly accurate distance measurements with the press of a button. They are ergonomically constructed to fit comfortably in your hand with easy access to both of the control buttons. Its range finding capabilities include: Distance, Rain, Hunt, Near, Horizontal Distance and Angle modes. The display brightness can be manually adjusted between 6 levels of brightness. The LRF requires a 3V CR2 battery and will automatically turn off after 15 seconds of no operation to save power.
