External factors may affect ranging accuracy, such as ambient light, weather conditions, target reflectivity, and target size.

• Larger objects are easier to target than smaller objects. If you are having trouble ranging a smaller target, range a larger target that is nearby instead.

• The device can target longer ranges in lower light conditions, such as on overcast days. Bright sunlight minimizes ranging ability.

• Rain minimizes ranging ability.

• The device can target longer ranges when measuring the distance to reflective or shiny objects.

• The device can target longer ranges when the angle to the target is closer to 90 degrees. A smaller angle to the target limits ranging ability.
