Bushnell Yardage Pro Sport 450 Rangefinders
|
Using advanced digital technology, Yardage Pro takes the guesswork out of measuring distances.
It delivers superb range performance to targets from 5 to 1,500 yards away at the touch of a button and is accurate to within a yard even if you're measuring in rain or snow or through foreground clutter like brush and branches.
Measuring a mere 1.5 by 4 by 2.75 inches and weighing only 6.8 ounces, the Yardage Pro is the smallest, most advanced laser rangefinder available. |
How a Laser Rangefinder Works
Bushnell's Yardage Pro rangefinders use an invisible, eye-safe Class 1 laser beam (as classified by the FDA) which is bounced off distant objects at the press of a button. Then, the rangefinder's high-speed digital clock measures the time it takes for a laser beam to reach a target and return to the unit. Next, using advanced digital electronics, the rangefinder instantly calculates the distance to within a yard and shows the range in either yards or meters on a through-the-lens LCD display. The entire process is so fast that less than a second elapses between the time you press the button to the time the exact range to your target is displayed.
Reflectivity of Target Types
Because rangefinders bounce laser beams off targets in order to take measurements, their range is partially determined by the targets' reflectivity. So, distances to reflective or "hard" targets like rock cliffs and semis can be measured from farther away than those to soft-surface targets. Ranges for moderately reflective targets, like trees, fall somewhere in the middle.
