Burris Eliminator III - Manual (Page 3)

3. A range is not successfully taken (RANGE FAULT). This
may happen because the target is beyond the range
capability of the scope on either the high side or the low side,
or the range cannot be correctly determined for other
reasons. To indicate this result the scope will flash the
bottom segments of the four range digits (_ _ _ _) and display
the “Range Fault, Dot Pattern” for the selected table. The
“Range Fault, Dot Pattern” is a display of the Dots that
would be illuminated for measurements of 100 unit intervals
out to 1200 units (100, 200, 300, 400, 500, 600, 700, 800,
900, 1000, 1100, and 1200 yards or meters) using the
currently selected Table. Many Tables are not capable of
reaching 1200 units. If this is the case, the Dot list will end at
the highest 100 unit available. This display also will be
corrected for the actual magnification setting. Again,
everything except the Dots will go out after ten seconds. All
the Dots will remain for the entire 90 sec.
The range displayed is the Line Of Sight (LOS) distance to the
target. The Eliminator III LaserScope has a built-in angle sensor
and it internally converts the LOS to horizontal distance for drop
compensation (Rifleman’s rule). The horizontal distance is
mostly what affects a bullet’s trajectory, so no matter what the
uphill or downhill angle, the Eliminator III automatically calcu-
lates the correct aiming point.
In the Eliminator III, both the hold over and windage are
corrected for your actual magnification setting. The best aiming
accuracy and resolution is at maximum magnification (as on
any variable power scope). If however, you are moving around
and want to use a lower magnification for finding targets quickly
in the larger Field Of View (FOV), the scope will still function:
giving the correct hold over and windage hold for your specific
magnification setting, range, and cartridge’s ballistics.
5. Set Up the Eliminator For Your Specific Cartridge
There are well over 4000 ballistic curves or Tables available for
use in the scope. You will need to select the correct one. This
is not as difficult as it sounds. We designate a ballistic curve by
specifying the drop in inches at 750 yards when zeroed at 100
yards and the Ballistic Coefficient (BC) for your chosen bullet.
A bullet’s BC is a number used in ballistic equations to specify
how fast the bullet slows down. Essentially it tells how slippery
it is. Long pointy front ends and boat tails give a bullet a higher
BC. The Sectional Density of the bullet (grains per unit area of
the bore) also affects its BC. Heavier bullets of a given diameter
tend toward better, higher, BCs. This scope accommodates BCs
down to .15 and up to .9 BC. There is more information on the
affect of BC at the end of these instructions in the section called
For Those New To Shooting Beyond 750 Yards and on our
website.
