If you want 640 resolution and a rangefinder in one scope, it's a strong choice. The RH50R gives you a 640x512 sensor at 60 Hz, a 50mm lens, a 1,200-yard LRF and 32GB of recording, backed by a 5-year warranty. It is also the same product as the Nocpix Rico 2 H50R.
InfiRay Outdoor makes the RICO Mk2 series. The RH50R is the same product Nocpix sells as the Rico 2 H50R, so the two share the sensor, lens and rangefinder. Warranty runs through InfiRay for 5 years, and we help you get in touch with them if the scope ever needs service.
