Burris Eliminator III - Manual (Page 6)

Windage compensation with the Eliminator III
Ranging and calculating the correct holdover for your cartridge
are done automatically. The scope also calculates the correct
windage offset for your specific cartridge at the measured range.
After a range is obtained, two numbers separated by a decimal
will appear at the top right of the display. That is your correct
windage hold-off for a 10 MPH crosswind. On the reticle there
are a series of horizontal dots that do not illuminate. At full
magnification the dots are MILs, but think of the Windage Offset
number as horizontal windage Dots. At lower magnification you
still use the dots to compensate for windage. Your Windage
Offset still reads in horizontal Dots. To use the Windage
compensation number divide the actual average crosswind by 10
(just move the decimal point one digit to the left) then multiply our
offset number by that value.
For example:
Actual average crosswind = 15 MPH
15÷10=1.5
Displayed 10 MPH offset = 1.4
Correct windage offset = 1.5 X 1.4 = 2.1 dots
So, range the target, read the 10MPH wind value and do your
arithmetic, find the illuminated hold over Dot along the lower post.
Follow horizontally along the sets of windage dots, (2.1 dots
in this example), into the wind, and squeeze off your shot.
Remember that all this works regardless of the magnification
setting of the scope.
Note: Compensating for wind is one of the most difficult tasks of
long range shooting. Wind changes from moment to moment and
the wind between you and your target is not necessarily the same
as where you are. Beyond wind meters, art and experience are
still very much involved in deciding on the average crosswind
value. Don’t forget that only the portion of the wind perpendicular
to your line of sight counts as crosswind.
Eliminator III Essentials
1. The hold over and windage features of this scope work at
all magnification settings.
2. The crosshair center must be used for ranging.
3. An illuminated aiming dot will remain lit for approximately 90
seconds. If you fail to shoot before the dot goes out, you will
need to re-range using the center crosshair.
4. During normal operation, the brightness of the reticle
illumination can be increased by pressing the up arrow button
and decreased by pressing the down arrow.
5. As with all rangefinders, several things can cause the Eliminator
III to be unable to determine the distance to a target. They
include obstacles between the scope and the target such as
grass, twigs, or leaves; rain, snow, mist or other airborne
debris; dirty objective lens; poor target quality for reflecting the
laser back to the scope, an unsteady hold, Long distances, or
low battery (or any combination of the above).
6. The parallax adjustment does affect range finding reliability a
little. Set parallax for the approximate range for best result at
long ranges.
7. If you have programmed the scope for a particular cartridge,
and the range to the target cannot be determined, the scope
will display four horizontal lines in the range display area, and
up to 12 illuminated dots that serve as a ‘custom’ Ballistic Plex
that is accurately calibrated to your cartridge. There will be
a dot for every 100 units of range available, starting at 100.
8. If the Eliminator III ever seems to be working improperly, there
is a good chance that it needs a new battery. First, simply
disconnect the existing battery and reinstall it and check for
function. If this doesn’t solve the issue, install a new battery.
9. If the Eliminator III LaserScope gets a distance reading that is
beyond the capability of the reticle’s drop compensation, the
bottom four dots will flash signifying to you that the target is out
of range. To estimate how far out you can expect drop and
wind compensation to work, see the following chart:
