FLIR Introduces FLIR ThermoSight Pro Series Thermal Weapon Sights

FLIR Boson Camera Core Powers New Thermal Line with Advanced Image Processing

Mounting a thermal weapon site like FLIR’s new ThermoSight Pro PTS233 as the primary targeting device is an easy proposition for any firearm with a standard Weaver or Picatinny (MIL-STD-1913) rail. Simply attach the sight to the top of the rail, check for proper torque of all fasteners, correct eye relief, and then head to the range.

FLIR SystemsWILSONVILLE, Ore.,-( FLIR Systems, Inc. (NASDAQ: FLIR) announced three rifle-mounted thermal imaging sights as part of the new FLIR ThermoSight Pro Series.

Available in three configurations, the FLIR ThermoSight Pro Series packs greater levels of performance and functionality into a compact and lightweight housing. Each FLIR ThermoSight Pro offers 320×256 thermal resolution, Bluetooth 4.0 and USB-C connectivity, and user-controlled imaging palettes and image enhancement filters.
