Pinhunter™ & Prism Lock™

Try ranging a pin or fluttering flag from over 300 yards away! 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.

Our products are battered and abused by thousands of enthusiasts every day and they are legendary for their durability. We know how to make a product rugged and we’ve poured that knowledge into the weatherproof Leupold golf rangefinder. So the next time you play through an ill-timed squall, you can be confident at least one friend will stick by you side - your Leupold golf rangefinder.

Fog Mode

Rain or shine, many golfers hit the links regardless of condtitions; that's why we designed Fog Mode.

Most rangefinders give measurements from the first target returned, which in some cases is the fog between you and the pin.

Your GX will cut through the weather and provide fast, accurate measurements to get you on the green.

You don't let anything stand between you and the cup, so why should your rangefinder?

Quick Set Menu

The Quick Set Menu is intuitive and easy to use, giving you fast access to the incredible performance of your GX golf rangefinder. All features and modes are easy to see without cluttering the field of view.

Scan Mode

When you want multiple readings in one quick sweep, just hold down the Power button and the display will continuously update with accurate line-of-site measurments. As an extra benefit, on courses utilizing prism technology, your GX will beep and the display will freeze the moment you scan past a prism-topped flag stick, assuring you of an accurate reading.
