Notes:
A = Scope Identification where:
1 = 1.7 - 10 power, identified on Table 2
2 = 3 - 18
power, identified on Table 3
B = Shot
distance, feet (meters)
C =
Magnification multiplier. A magnification multiplier of 3 is associated with a lung shot; a magnification
multiplier of 4 is associated with a heart shot.
E = Magnified
field of view, as calculated here.
D = Required
magnification for either a lung or heart shot, calculated by Mag = (Mag X) x
(SD/100), rounded
up to the nearest magnification whole
number. If the required magnification is less than the scope s
minimum power, the scope s minimum power
is shown.
F = Magnified
field of view to animal length ratio for an impala, as calculated here. The animal
length of an
impala is assumed as
4.7 feet (1.4 meters) as indicated in Table 1.
G = Magnified
field of view to animal length ratio for a kudu, as calculated here. The animal
length of a
kudu is assumed as 6.2 feet (1.9 meters)
as indicated in Table
1.
H = Magnified
field of view to animal length ratio for a blue wildebeest, as calculated here. The animal
length of a blue wildebeest is assumed as 7.1 feet (2.2 meters) as indicated in Table 1.
