Lightweight and maneuverable, it allows you to scan the darkness for eyes, identifying animals to ensure that you only observe the quarry you intend, without disturbing them, and without the need for lamps or lights. With no excess functions or buttons, it is incredibly easy to pick up a unit and immediately begin your search for nocturnal wildlife.Crystal Clear Night Vision viewing940nm Infra-Red light built in for guaranteed performanceSilent Backlight & Illimination adjustment buttonsIdentification up to 100mFixed focusLightweightHand-heldSimple to useOn / Off switchIncludes belt pouchIdeal for spotting quarry at close distances whilst remaining completely covert*Range subject to weather conditions Includes:1 x SENTINEL PRO1 x 12 volt lithium polymer charger with charging indicatorBelt Pouch1 x Quick start guide1 x 24 month guarantee card (Battery guaranteed for 12 months)
