Limit the range of measurement to 195 ft.
 Aiming at glossy surfaces may deflect the laser beam, and affect accuracy.
 Colorless liquids, dust-free glass, Styrofoam, or other semi-permeable surfaces may
cause measurement errors.
 Periodically perform test measurements, especially after extended use and before,
during and after critical measurements.
