MEASURING RANGE AND ACCURACY
The measuring range of the Leica Geovid HD-B is up to
±1825m/2000yds. The maximum range is achieved
with high reflective target objects and a visual range of
10km/6.2 miles.
Note:
To reliably detect very distant objects, we recommend
holding the binoculars very steadily and/or placing
them on a stable surface.
The measuring range is influenced by the following
factors:
Range Higher Lower
Color White Black
Angle to lens Perpendicular Acute
Object size Large Small
Sunlight Low
(cloudy) High
(midday sun)
Atmospheric
conditions Clear Hazy
Object structure
conditions Homogeneous
(wall of building) Inhomogeneous
(bush, tree)
In sunlight and with good vision, the following ranges
and accuracies can be achieved:
Range Approx. 10m/yds to
1825m/2000yds
Accuracy Approx. ±1m/yd up to 500m/yds
Approx. ± 2m/yds up to 1000m/yds
Approx. ± 0.5% above
1000m/1000yds
