I've got an old model Leica Geovid Rangefinder binoculars. A simple model, has a small rectangle in the vision and a button. It gives you the metres when the button is pushed. A forums member working for a gunshop here sold me it for a big discount, like to others at the time. A month later the new model came out which had something extra in terms of angle of the shot as well.

A fine set of clear good quality binoculars with the range finder included.

I still use my older Swarovski non range finder binoculars a lot as well, in 8x42.

The Leicas are my only form of rangefinder.
