It measures the angle-compensated distance to your target and provides an LED pin for the shot. A bow sight with a mounted digital laser range finder? Yeah, we did that. Set different pin colors, so you can find the right distance fast. Save pin settings for multiple arrow profiles for different hunting styles. The Laser Locate(TM) feature lets you mark where the target was located when the shot or range was taken. One-year battery life means more time hunting and more confidence in your shot. MULTIPLE ARROW PROFILES Choose from single pin or multipin configurations, and choose from 2 different colors of pins: red or green. You can also move your range pin stack up or down, so you don&';t have to recalibrate the entire stack. LASER LOCATE FEATURE Laser Locate enables the use of a compatible Garmin GPS device (sold separately) to show the target&';s exact location when the shot or range was taken. DUAL-COLOR LED PINS Clearly see bright LED pins over your target, unobstructed by physical pins. These pins automatically adjust brightness according to conditions, and Xero A1i gives you the option of using red or green LEDs. LASER RANGE FINDER Get instant angle-compensated distance to game up to 100 yards away or up to 300 yards away on reflective targets, at rest or full draw. LEVEL INDICATORS Eliminate cant from your shot with built-in level indicators that appear as blinking pins on your sight. SILENT BUTTON TRIGGER Mount the button in the best location for your grip so one finger can silently activate the laser range finder to give you the distance and exact aim point you need for the shot. PRACTICE MAKES PERFECT Record your performance during practice shooting sessions, and review your stats for various ranges and sessions over time. BATTERY LIFE Get up to 1 year of battery life - about 25,000 ranges - from 2 lithium AAA batteries (not included), so you can go from target practice to hunting season without missing a beat.
