The Bushnell 4 x 20 Medalist Golfing Laser Rangefinder is an advanced premium laser rangefinder comprised of Digital Technology allowing range readings from 5-1000 yards / 5-914 meters. Measuring 1.7 x 4.5 x 3.8 inches, the 9-ounce Medalist delivers superb and accurate range performance to +/- one yard. The Medalist features PinSeeker technology, SCAN Mode, 4x Magnification and Multi-Coated Optics for enhanced viewing.
The Medalist emits invisible, eye safe, infrared energy pulses. The Medalist's advanced Digital microprocessor and ASIC chip (Application-Specific Integrated Circuit) results in instantaneous and accurate readings every time. Sophisticated digital technology instantaneously calculates distances by measuring the time it takes for each pulse to travel from the rangefinder, to the target and back. The ranging accuracy of the Medalist is plus or minus one yard / meter under most circumstances.
The maximum range of the instrument depends on the reflectivity of the target. The maximum distance for most objects is 500 yards / 457 meters while for highly reflective objects the maximum is 1000 yards / 914 meters. The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter the color, longer is the range. Red is highly reflective, 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.
