There has been upgraded rangefinders in 56mm???? Sales in the UK for 42mm is considerably higher than 56mm versions, but as you suggest, more people are investing in thermal for day and night use???Or it could be because they don’t yet have a suitable range of THERMAL devices?!
Has anyone noticed that none of the Big 3 have introduced an all-out low light set of bins (56mm) for some years now? This to me suggests the market for such is dead and thermal is the new king of dawn & dusk.
