Bushnell Laser Rangefinder Yardage Pro 400 Infrared LCD Display

Description

The YA RD AGE PRO® 40 0 emits invisible, eyesafe, infrared energy pulses. Sophisticated circuitry and a high speed c lock are used to instantaneously 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® 400 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 400 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 r e f l ective, for example, and allows longer ranges than the color black, which is the least reflective 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 surface 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 affect the ranging capabilities of the unit. The less light (e.g. overcast skies) the farther the unit’s maximum range will be. Conversely, very sunny days will decrease the unit’s maximum range.
