Overview

The Guide TU 650 LRF 3.0 is a 640x512 thermal riflescope with a built-in laser rangefinder, rated to detect targets out to 2800 yards and range them out to 1600 yards.

Its shutterless design is meant to remove the periodic recalibration click and momentary image freeze that some thermal cores rely on, keeping the feed continuous through a shot. A 1920x1080 AMOLED display, 10 reticle options and 7 color palettes give more control over how the thermal image is presented than a fixed single-palette unit would. The integrated Class I rangefinder, rated under 1mW output, adds distance data without a separate handheld unit.

  • 640x512 thermal resolution
  • Integrated laser rangefinder to 1600yd
  • Shutterless design
  • 1920x1080 AMOLED display

Who it's for

Hunters who need thermal detection and integrated ranging in one unit, particularly for low light or after-dark hog and predator hunting where detection range matters more than daylight optical clarity.

Pros and cons

Performance notes

The shutterless core is designed to avoid the momentary image freeze some thermal sensors produce during recalibration, keeping the view continuous during a shot. The integrated laser rangefinder is rated Class I with output under 1mW and reaches out to 1600 yards, separate from the sensor's 2800 yard detection range. A 1920x1080 AMOLED display, 3.7x base magnification with 8x zoom, and a throw lever for quick zoom access round out the control layout.
