range finders
Optical distance devices
Range finders are devices that measure the distance between the user and a target.
They work through various technologies—laser, radar, ultrasound, or optical triangulation.
Golfers use them to gauge distance to the pin, hunters to estimate shots, and military personnel to direct fire.
