Rangefinder calibration

[szekiat]

My baby's RF has finally gone out of calibration after years of hard use. Anyone ever done a DIY or know who i should send it to in the UK? Any tips at all would be great. The Xpan does the mainstay of my street work these days so i'd like the calibration adjusted definitely. Who can i trust?

I'd start with Hasselblad and see if they have any recommendations.
