HOW OUR DIGITAL TECHNOLOGY WORKS
The TOUR V4 SHIFT WITH PINSEEKER emits invisible, eye safe, infrared energy pulses. The TOUR V4 SHIFT's
Advanced Digital microprocessor and ASIC chip (Application-Specific 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 rangefinder, to the target, and back.
RANGING ACCURACY
The ranging accuracy of the TOUR V4 SHIFT is plus or minus one yard/meter under most circumstances. The
maximum range of the instrument depends on the reflectivity of the target. The maximum distance for most
objects is 700 yards/640 meters while for highly reflective objects the maximum is 1000 yards/914 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.
