HOW OUR DIGITAL TECHNOLOGY WORKS
e Tour® Z™ emits invisible, eye safe, infrared energy pulses. e Tour® Z™ Advanced Digital microprocessor
and ASIC chip (Application-Specic Integrated Circuit) results in instantaneous and accurate readings every time.
Sophisticated digital technology instantaneously calculates distances by measuring the time it takes for each pulse to
travel from the rangender, to the target, and back.
RANGING ACCURACY
e ranging accuracy of the Tour® Z™ is plus or minus one yard / meter under most circumstances. e maximum
range of the instrument depends on the reectivity of the target. e maximum distance for most objects is yards
/ meters while for highly reective objects the maximum is yards / meters.
Note: You will get both longer and shorter maximum distances depending on the reflective properties of the particular target and the environmental conditions
at the time the distance of an object is being measured. The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter
the color, the longer the range. Red is highly reflective, for example, and allows longer ranges than the color black, which is the least reflective color. A shiny
finish provides more range than a dull one. A small target is more difficult to range than a larger target. The angle to the target also has an effect. Shooting
to a target at a 90 degree angle (where the target surface is perpendicular to the flight path of the emitted energy pulses) provides good range while a steep
angle on the other hand, provides limited ranging. In addition, lighting conditions (e.g. the amount of sunlight) will affect the ranging capabilities of the
unit. The less light (e.g. overcast skies) the farther the unit’s maximum range will be. Conversely, very sunny days will decrease the unit’s maximum range.
E.S.P.™ (Extreme. Speed. Precision) optimizes measurement accuracy depending upon target conditions. e laser
analyzes multiple individual measurements to the target and calculates and displays the best possible result. Target
variations such as reectance, shape and color can aect the accuracy of a laser measurement, but E.S.P.™ automatically
assesses the conditions and improves the measurement up to ½ Yard Accuracy whenever possible from – yards.
When this does occur, display precision will be rened to /th yard readout.
