FLIR ThermoSight® Pro Series

Price: $2,199.00

The new FLIR ThermoSight Pro Series offers 320×240 thermal resolution and packs greater levels of performance and functionality into a remarkably compact, nimble, and lightweight housing made of rugged aircraft-aluminum alloy. With an emphasis on reliability, the FLIR ThermoSight Pro is the perfect addition to any hunting or security weapon platform, striking an ideal balance between size and performance.

The advanced image processing of the ThermoSight Pro delivers brilliant, clean thermal imagery in low contrast daylight scenes (e.g., smoke, haze, fog, rain, light foliage), as well as in total darkness. At the heart of the ThermoSight Pro is the new FLIR Boson thermal sensing core, featuring a 12 μm pixel pitch sensor and industry leading on-chip video processing. The ThermoSight Pro PTS233 has a 19mm lens with a 12 degree field-of-view, plus 1.5x optical zoom and 4x digital zoom.

The uncompressed video signal is paired with a bright high definition display to generate a crisp, high quality image for better detection and classification in the field. FLIR’s patent pending HVT reticle technology provides clear visibility against even the most difficult to discern backgrounds. Multiple palettes and reticle patterns, plus useful icon and graphic overlays, offer a superior, customizable viewing experience. A digital compass/inclinometer enables precision range and target orientation.

The ThermoSight Pro registers memorable moments with shot activated video recording and image capture. Internal storage provides remarkable capacity: up to 2.5 hours of video or 1,000 still images with the ThermoSight Pro PTS233. Stored video can be accessed and managed through Bluetooth 4.0 and USB-C connectivity.
