Spark core monocular - Armasight Spark CORE Night Vision Monocular

I researched many night vision monoculars before making my purchase of the Spark CORE monocular at Optics Planet, the Spark is very clear in resolution, the infrared light provided with unit could be brighter, but worked well for 10-15 yards in near total darkness, the adjustments were a little stiff to begin with, but loosened up with a little use, overall I am very satisfied with my Spark CORE, but I do suggest buying the Armasight long range infrared illuminator to go with the unit, it will make you appreciate the Spark even more.
