Ballistic Information System BIS™
For hunting, the equipment has a ballistic information system BIS™, with which it is possible
to display the required correction value for the aiming point depending on the estimated range.
Note: The so­called point of impact shows how many centimetres or inches higher or lower than
at target range the shot will impact at the measured distance. The correction value for the aiming
point is the correction required in order to shoot back on target.
The correction value for the aiming point is displayed approx. 1.5 seconds after the range. A
preceding "H" means that higher aiming is required (Fig. 5) and a preceding "L" means that
lower aiming is required. The display is given in centimetres for the EU settings and in inches
for the US settings.
For safety reason, the holding points are given only for ranges of up to
500 metres. For greater ranges, the display shows "HIGH".
Please note that the ballistic information system BIS™ is not to be used as a replacement for
the hunter's assessment of the situation, but rather to support and increase hunting safety.
We recommend shooting exercises from different ranges, which can be used to check the
correct match of the specifications with the actual points of impact.
Selection of the appropriate ballistic programme
The selection is made using the SET button (Fig. 1/4). A short press of the SET button will display
the setting currently selected. An extended press of the button for 3 seconds will cause the
display to start to flash and the setting to then change every time the SET button is pressed. The
setting options are called up successively.
The ballistic curves are numbered from 1 to 6. The EU or US presetting shows respectively whether
you have selected the measuring units of metres/centimetres (EU display) or yards/ inches (US
display).
If your riflescope is sighted in at 100 metres/100 yards, select one of the curves from range EU
1 to EU 6 / US 1 to US 6.
If your riflescope is sighted in at SID / GEE (for EU settings only) or at 200 yards (for US settings
only), select one of the curves from range EU
