Laser Rangefinders

A laser rangefinder is a distance-measuring instrument that uses laser technology to calculate the distance to targeted objects. Accuracy is +/- 1 yard, and the distance is displayed instantaneously on a built-in, through-the-lens Liquid Crystal Display.

Angle Range Compensation (ARC) Targeting Modes: Bow - Provides true horizontal distance from 5 to 99 yards. Rifle - Provides bullet drop/holdover data in inches from 100 to 800 yards.

Through-the-lens LCD Display
Bushnell® Yardage Pro® rangefinders are fast and easy to use because everything you need to know is displayed on our built-in, through-the-lens LCD (Liquid Crystal Display).

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 with the press of a button. Then, the rangefinder's high-speed digital clock measures the time it took for a laser beam to reach a target and return to the unit. Next, using advanced digital electronics, the rangefinder instantly calculates the distance within + / – 1 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 generate a laser beam to the time the exact range to your target is displayed.

Reflectivity of Target Types
Because rangefinders "bounce" a laser beam off the target in order to take a measurement, their range is partially determined by the reflectivity of the target. In other words, hard or "reflective" targets – like a rock cliff or semi-truck – can be measured at greater distances than soft surface targets – like a deer. Ranges for moderately reflective targets, like trees, fall somewhere in the middle. Most experienced hunters will use their rangefinder to frequently estimate ranges to near and distant landmarks before they actually encounter a game animal. By "pre-measuring" ranges to spots where a trophy is likely to appear, they can concentrate on making an accurate shot when the moment of truth arrives.

Selective Targeting Modes:
Rain - This feature compensates for precipitation to guarantee an accurate distance measurement through rain or snow.
Reflector - This feature increases the maximum measurement range for most highly reflective objects and is built into all of our rangefinders.

SCAN:
SCAN across the course while viewing a continuously updated LCD display of the distance between you and your target.


BullsEye:™
Geared for close-range use, this mode acquires the distances of small targets and game without inadvertently measuring background target distances. When more than one object is acquired, the closer of the two objects is shown on the LCD display.


Brush:™
Ignores the foreground, such as brush, boulders and tree branches, and provides distances on the LCD display to background objects only.


PinSeeker:™
Designed exclusively with the bottom of the cup in mind, this mode allows easy acquisition of the flag without inadvertently capturing background target distances. When more than one object is acquired, the closer of the two objects is shown on the LCD display.

Slope - Measures slope, +/- one degree of angle, and compensated range, based upon ball trajectory and type of club used. All shown on LCD display.
