Ranger LT 6.5x42 is equipped with integrated LED IR illuminator with 940 nm wavelength. Integrated IR illuminator is practically invisible with a naked eye. It allows hunter observe animals without the risk of scaring them. 15-stage power adjustment range gives possibility to vary operation distance greatly. At maximum power integrated IR illuminator of Ranger LT 6.5x42 is comparable to the majority of independent (not integrated in NV devices) IR illuminators that exist on the market.
Digital NV devices can be turned on in the daylight without the fear of being damaged either immediately or in the long term.
As a sensor Ranger LT 6.5x42 uses a black and white CMOS camera of high resolution (640x480 pixel). The image is displayed on the screen of similar resolution.
Current information about the status of the device, depicted in the form of blue icons and numbers, is located on the data panel in the lower portion of the screen, and does not interfere with the image observed. When switching between various functions, the respective large sized icon appears in the right portion of the screen.
Device works on 6 AA batteries including rechargeable. One battery set can power the device for 6…12 hours, depending on the mode of operation of integrated IR illuminator.
Batteries are located in a special container, which is inserted in to the battery compartment of device. Delivery set includes additional container – when batteries are depleted it is possible to insert additional container with inserted beforehand new batteries in to the battery compartment.
Operation time can be significantly prolonged by using high-capacity external power supply units attached to the Ranger LT 6.5x42 via an External Power jack. During extended use in freezing weather, the external power supply units can be stored in a warm place (under the operators’ clothes) for preventing fast discharging .
The Ranger LT 6.5x42 is equipped with a jack allowing transmission of video signal to external video recording devices (screen, TV-set or external recording device).
