The YA RD AGE PRO

750 emits invisible, eyesafe, infrared energy
pulses. Sophisticated circuitry and a high speed clock are used to
i n s t a n t a n eously calculate distances, by measuring the time it takes for each
pulse to travel from the rangefinder, to the target, and back .

The ranging ac c u r acy of the YA RD AGE PRO
®
750 is plus or minus
one yard / meter under most circumstances (see description of “Pr ec i s io n ”
indicator below). The maximum range of the instrument depends on the
r e f l ec t i v i ty of the target. The maximum distance for most objects is
750 yards / meters while for highly reflective objects the maximum is
999 yards / meters. Note: You will get both longer and shorter maximum
distances depending on the reflective properties of the particular target and
the environmental conditions at the time the object is being distanced to.

The color, surface finish, size and shape of the target all effect reflec t i v i ty and
range. The brighter the color, the longer the range. Red is highly reflec t i v e ,
for example, and allows longer ranges than the color black, which is the least
r e f l ective color. A shiny finish provides more range than a dull one. A small
target is more difficult to range than a larger target. The angle to the target
also has an effect. Shooting to a target at a 90 degree angle (where the target
s u r f ace is perpendicular to the flight path of the emitted energy pulses)
provides good range while a steep angle on the other hand, provides limited
ranging. In addition, lighting conditions (e.g. the amount of sunlight) will affec t
the ranging capabilities of the unit. The less light (e.g. overcast skies) the
f a rther the unit’s maximum range will be. Conversely, very sunny days will
d ecrease the unit’s max imum range.

the “mode“ button (see Figure 3) (lower right hand side of the unit) and hold it down for
approximately 5 seconds. If you are changing from yards to meters, a change in unit of
measure will be indicated by the illumination of the ME T ER indicator while the YA R D indicator

S TAN D AR D ( LCD Indicator - none) – This setting allows most targets to be distanced up to
75 0 yards. Used for moderately reflective targets that are typical of most distancing situations.
S C A N ( LCD Indicator - “SCAN”) – This mode allows the range to be continuously updated for
10 seconds when the fire button remains depressed. It can be used to scan an area containing
several objects or a single object that is moving. Note: Objects further away require a slower
scanning pace than objects at a closer distance. The minimum distance in this mode is the
same as in the standard mode.

Gently blow away any dust or debris on the lenses (or use
a soft lens brush). To remove dirt or fingerprints, clean with a soft cotton clo t h ,
rubbing in a circular mo t ion. Use of a coarse cloth or unnec e s s a ry rubbing may
s c r a t ch the lens surface and eventually cause permanent damage. For a mo r e
