FOX 35 ELITE II thermal sight is a great choice for customers who require good image quality, proven technology and an excellent price. Night Pearl FOX 35 ELITE II uses VOx sensor technology and a 35mm objective lens. An important advantage of the thermal sight is the compact and lightweight body while maintaining a solid recoil-resistant construction. These properties do not appear very often with thermal imaging sights of the same class. Optical magnification is sufficient for use at greater distances.
