Calculating a shot using dead reckoning or peripheral devices can be tedious and cumbersome when a huge buck comes into view. The Bresser® Ambition 100 Yard Archery Laser Rangefinder has precision optics to give you an accurate distance quickly and stealthily. This lightweight rangefinder can be easily mounted on most modern compound bows and crossbows as well as three axes of adjustment for proper pin-point positioning. You'll see an accurate reading of your target up to 100 yards on an OLED display that can be easily read without disengaging your bow. The constantly active scan mode will keep you fully aware of the distance to potential targets.
