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

• 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 brightly colored, reflective, or shiny objects. Black objects are less reflective, and can be targeted at shorter ranges.

• Larger objects are easier to target than smaller objects. For example, you should target the flag instead of the pin.

• 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.
