Measurement in Reflectorless mode
The intensity of the reflection from the target determines the distance the instrument
can measure in this mode. The color and condition of the target surface also affect the
measurable distance, even if the targeted objects are the same. Some less-reflective
targets may not be measured.

Measurable distances may be shorter or measurement intervals may be longer in the
following cases:
• the angle of the laser against the target is small
• the surface of the target is wet
In direct sunlight, the measurable distance may be shorter. In this case, try to throw a
shadow on the target.
Targets with completely flat surfaces, such as mirrors, cannot be measured unless the
beam and the target are perpendicular to each other.
Target You can measure approximately...
Traffic signs, reflectors 800 meters (2624 feet)
Paper (white), veneer (new) 450 meters (1476 feet)
Wall (brightly painted), brick 150 to 300 meters (492 to 984 feet)
Target You can measure approximately...
Traffic signs, reflectors 500 meters (1640 feet)
Paper (white), veneer (new) 300 meters (990 feet)
Wall (brightly painted), brick 100 to 200 meters (330 to 660 feet)
Make sure there are no obstacles between the instrument and the target when taking measurents.
When you need to take measurements across a road or a place where vehicles or other objects are frequently
moving, take several measurements to a target for the best result.
