While looking through the Bushnell Pro X3+, press and release the Power/Fire button to activate the display. If the display icons and numbers are blurry, rotate the eyepiece in either direction until they focus (see "Adjusting the Eyepiece" below). Next, placing the aiming circle (center of the display) over a target at least 5 yards away, press and hold the Power/Fire button until the "line of sight" distance is displayed near the bottom of the display (see "Display Indicators" below). Crosshairs surrounding the aiming circle indicate that the laser is transmitted. After a range is acquired and displayed, you can release the Power/Fire button. The crosshairs surrounding the aiming circle will disappear once the Power/Fire button is released (i.e., the laser is no longer transmitted).
Once activated, the display will remain visible and display the last distance measurement for 10 seconds. You can press the Power/Fire button again at any time to range to a new target. The maximum time the laser is transmitted (active) is five seconds. To re-fire, press the button down again.
NOTE: once the Pro X3+ has shut off, it will always default back to the last mode used.
Your initial battery should last for a few months. If you start to experience any issues with the performance, replace the battery with a high quality (Panasonic, Duracell, or Energizer), CR-2 3 Volt Lithium battery that is right out of the package. Once you replace the battery, press & hold the fire button for 10 seconds. We recommend carrying at least 1-2 spares in your golf bag so that you always have a fresh new battery for full functionality.
