The iRay RICO 2 H75R is a thermal weapon sight with a 640x512 resolution sensor and 75mm germanium objective lens. The 12 micron pixel pitch gives this unit finer detail resolution than the more common 17 micron sensors, translating to cleaner target identification at range. A built in laser rangefinder (LRF) reads distance to target so you can hold or dial without switching to a separate device. The 4x optical magnification with up to 8x digital zoom gives you flexibility from close quarters to extended range.The 60 Hz refresh rate keeps the thermal image smooth during panning and tracking, with no lag or stutter that cheaper 30 Hz units show on moving targets. Multiple reticle options are available including one user customizable (DIY) pattern, one dynamic, and six static reticle styles. The RICO 2 platform records photo and video onboard, useful for documenting hunts or reviewing shot placement. This is a high end thermal optic built for serious night hunting and tactical applications where a 640 core and LRF integration are worth the investment. The H75R model's large 75mm objective lens pulls in more thermal energy than smaller lens options, giving you detection range that smaller thermals cannot match.
