What to do if Laser Technology Measuring Instruments give erroneous readings?
- J
  Joshua SmithAug 3, 2025
  To address erroneous or not repeatable readings with your Laser Technology Measuring Instruments, first ensure you have a clear line of sight to the target. Check the scope alignment. If it's raining or foggy, activate the Weather Mode. Remember that when Weather Mode is active, the minimum range becomes 61 meters. Also, when measuring a short range to a small target, try aiming slightly above the target.

Why does Laser Technology Measuring Instruments have limited range?
- S
  Steven ScottAug 7, 2025
  If you are experiencing limited range with your Laser Technology Measuring Instruments, consider the following: * Ensure a clear line of sight to the target. * Be aware that rain or fog can reduce the unit’s maximum range. Activate the Weather Mode; note that the minimum range will be 61 meters when this mode is active. * Avoid acquiring targets through glass, as this also reduces the maximum range. * Make sure the lens is clean and free from scratches.

What to do if Laser Technology Measuring Instruments show E01 error code?
- C
  Christina LewisAug 18, 2025
  If your Laser Technology Measuring Instruments displays an E01 error code and provides no range or speed readings, try measuring a wall approximately 15 meters away. Check the scope alignment and restore the factory defaults. When measuring a short range to a small target, aim slightly above the target.
