Overview
A 640x512 thermal riflescope with a 50mm lens, built-in rangefinder and ballistic calculator, offering 1-8x digital zoom and adjustable 30/50/60Hz refresh rates.
Reviewers with prior experience on ATN, Pulsar, AGM and iRay thermals frame this scope as a value alternative in the 640 sensor class, with one buyer confirming a 771 yard coyote shot using its ballistic calculations. Image quality reviews are split: most call it clear for the price, but at least one reviewer describes it as mediocre with a slight lag compared to pricier units. The 35mm and 75mm interchangeable lenses sold separately are worth noting before buying, since only the 50mm ships with this unit.
- 640x512 sensor, NETD under 20mK
- 50mm F1.0 lens, 2.8x to 22x zoom
- Built-in rangefinder and ballistic calculator
- Adjustable 30/50/60Hz refresh rate
Who it's for
Fits hunters moving into thermal optics who want a rangefinder and ballistic calculator bundled in rather than bought as separate accessories. Less suited to buyers who have used premium 640 sensor thermals and expect image clarity to match higher-priced brands.
