Distance meter with positioning pin

Positioning pin

— a design feature found in rangefinders — mainly laser ones.

The position bracket is a special stop on the body of the device, designed for convenience when measuring distances in some situations. This stop is one of the reference points — that is, by setting the appropriate settings, you can measure the distance not from the front or rear edge of the case, but from the bracket. This is useful, in particular, when measuring the distance from various edges — door and window openings, the edges of countertops and borders, etc.: in such situations, it can be convenient to rest the bracket on the starting point of measurement.
