I believe it was about 3 years old prior to myself owning the unit from a gentlemen. I had it for a short period of time myself as use thermal lrf. I know they were in the area of £600 new, so great value. Never had any issues with the glass, has the classic Zeiss T coating. Rangefinger electronics worked great and accuratley. Bigger objective than the majority of range finder monoculars available, so more light intake and bigger field of view. And with a 8 x starting mag, its almost like a replacement for bino's... with the advantage of the rangefinder onboard of course.
