The Viper Night Vision 5x52 NVM-50D is a sensitive night vision monocular with a built-in infrared illiminator that lets the user see in total darkness. The lens system magnifies the view by a factor of 5x - this is ideal for garden Fox and wildlife watching and general security and more serious usage.

The instrument features large high-resulution 52mm optics, ergonomically positioned operating buttons and a rubber armoured tough aluminium body. The eyepiece has a soft, comfortable rubber eye-cup that can be folded down for full field viewing for all users including spectacle wearers. The lens and eyepiece both have fully adjustable focus for pin sharp viewing.

The body features ergonomic and comfortable design. The base has a tripod mounting point.

A nice feature of the NV-50D is a handy tether and catch to retain the lens cap safely when using the device.

The Viper 5x52 monocular is supplied with a soft storage and carry case. User supplied battery required: 1x Long-life Lithium CR123A or equivalent (not included).
