What determines the maximum range of a laser rangefinder?
The maximum range that a laser rangefinder can measure is determined by the reflectivity of the target and the unit’s operational sensitivity. A bright flat surface such as a building or large metal object may allow models that normally have a 400 yard range to deliver a precise measurement out to 900 yards. As manufacturers have refined the technology, making the units smaller and more sensitive, their normal operating range has increased. Less reflected energy is required and marginal reflections will still provide enough return to give a precision distance reading. Older versions and some of the less expensive models require a higher level of reflected energy to consistently register a distance.
