Firefield Spartan Night Vision Monoculars
Firefield Sparta Night Vision Monoculars are available in three sizes. The 1x24 goggle is light enough to be used with a head mount. The 3x42 and 4x50 are larger and must be handheld. Both the larger models are IPX4 weather resistant and have a 100mW IR illuminator built in. Each of the three is powered by one CR123 battery that can last up to 20 hours, and come with a case, user manual, and a cleaning cloth.
