Kestrel 4500 Horus (Ballistics) - Manual (Page 10)

19
Note: The Range Card will display range values up
to 4000 yards, or the closest equivalent in meters,
depending on the range increment.
Remaining Velocity
• A small dot will appear to the left of the muzzle
velocity value to indicate the bullet is in the
transonic range.
• A larger dot will appear to the left of the muzzle
velocity value to indicate the bullet is in the
subsonic range.
BALLISTICS SCREEN
The Ballistics screen displays complete information about
the ballistic solution that pertains to the currently selected
target and gun. The only parameter whose value can be
altered in this screen is the “Range” (this can be done by
using
and to adjust the value).
• Use or to scroll to a particular parameter.
• Use to enter into a parameter screen for further
information about it or change unit of measure.
• Use to return to the Ballistics screen.
Note: An R or an L will appear beside each solution to indicate
which side of the target you should aim.
ATrag Signature Feature
TRUE DROP
In an ideal world, shooters would go into the field knowing
exactly how their chosen combination of gun and ammuni-
tion will perform, calculated ballistic solutions would always
be correct, and a properly delivered shot would always hit
the target. In the real world, ballistic data is often imperfect,
and even well delivered shots often miss.
The best way to deal with this is to allow ballistic parameters
to be adjusted to reflect what is actually observed. When
this is done correctly, overall accuracy can be significantly
enhanced. The Horus Kestrel includes a Drop Truing screen
to support this valuable function.
• When all parameters are set, press to escape.
• On the Gun screen, use to highlight the
“True drop” item
• Press to enter the Drop truing screen.
• In the Drop Truing Screen, use or
to highlight the parameter you wish to change.
• The parameters that can be adjusted are “BC” (ballistic
coefficient), “MV” (muzzle velocity), or “Range”.
• This adjustment is made so that the calculated
elevation correction matches what is actually
observed.
QUICK KEYS: DIRECTION OF FIRE &
WIND SPEED
The Direction of Fire (DoF) and Wind Speed (WS1 & WS2)
Quick Key feature allows you to quickly and easily change
the values of these parameters from the Main Horus screen
without entering into the Target screen. It minimizes the
number of button presses and time by instantly capturing
these values from one screen- the Main Horus screen.
Direction of Fire Quick Key
• Pressing the button while Tgt is highlighted will
enter the DoF setting mode.
