A vintage 'Rangematic' distance finder.

In excellent, seldom used condition.

In original box with instructions and additional paperwork.

The Rangematic distance finder is a vintage optical device, often used for hunting or surveying, that uses a system of internal mirrors and lenses to superimpose two images in its eyepiece, allowing the user to estimate distance by rotating a dial until the images align, revealing the range in yards or meters. It's a non-laser method for calculating distances to objects like trees, animals, or buildings, essentially a manual rangefinder before modern laser technology became common.
