• Additional rangefinder settings are available in the Rangefinder section of the main menu.
• To select a unit of measurement (meters or yards) go to Units of Measure  subsection of the General Settings section.

Additional Information:

• The accuracy and distance of the measurement depends on the reflection coefficient of the object surface and weather conditions. The reflection coefficient depends on the texture, colour, size and shape of the object. Generally, lighter coloured objects and those with a shiny surface will have a higher reflection coefficient.
• Measurement accuracy can be influenced by the light conditions, fog, haze, rain, snow, etc. The results may be less accurate when operating in sunny weather or if the rangefinder is directed towards the sun.
• It is easier and more reliable to measure the distance to large objects than to small ones.
