The Athlon Cronus ATS Pro 35C-400 Thermal Clip-On (Athlon part no. 210140) is a thermal imager that clips on in front of a daytime riflescope, so you can add thermal imaging to a daytime riflescope you already own. It uses a 400×300 sensor with a 12 micron pixel pitch and a low NETD rating for cleaner, sharper images with strong contrast. A 0.39-inch OLED display with 1200 x 900 resolution shows that image, and Wi-Fi connects it to the Athlon Thermal app for recording and sharing. Auto-shot recording, one shot zero and an eco mode make it practical for varmint and predator hunting.
