Overview
The Armasight Warden 640 Thermal Monocular costs $3,499, the most expensive thermal monocular in this lineup, detecting heat signatures out to 1,300 meters with a wide 22x18-degree field of view.
Its 640 in the name reflects the same 640x512 sensor resolution as the Steiner Nighthunter H35, but at nearly double the price — the wider field of view is the main differentiator between the two.
