Welcome to the most accurate line of Golf Rangefinders available. With Leupold precision optics, proprietary laser technology that ranges the pin easily, even at extended range, and a scan mode available at any time, there is simply no other brand of golf rangefinder that can keep pace.

It's not a problem for a GX golf rangefinder from Leupold. Every GX golf rangefinder has been precisely calibrated to fire a laser beam exactly at the target in the crosshairs. The proprietary beam geometry improves laser returns from the pin and the advanced GX software accurately separates those returns from objects in the background. On courses that utilize prism technology ranging a distant pin is even easier thanks to the Prism Lock. Hold the top button to scan the area around the pin, your GX will beep and the display will freeze the moment it identifies a prism-topped flag stick. Whatever the course, you can be sure the results you receive from the GX are the most precise available from any golf rangefinder on the market. Leupold's exclusive PinHunter Laser technology, fog mode, and seven selectable aiming reticles hunt down the pin consistently in virtually any weather condition. Prism Lock technology affords unmatched accuracy by using highly reflective prisms already incorporated into many course features and pins to obtain a high intensity return to your GX-1i. With Prism Lock, holding the rangefinder steady becomes much less of a concern, and you can be assured your distance measurement is exact. Additionally, the GX-1i is tournament legal, offering line-of-sight distance measurement only.
