Leupold GX-4 Laser Golf Rangefinder Review

The GX-4 Rangefinder is the premier rangefinder in Leupold's GX series. Offering all the features that make Leupold rangefinders some of the best in the business like PinHunter, Prism Lock, and Fog Mode, the GX-4 Rangefinder can also use information on slope, temperature, and altitude to display adjusted and highly accurate distance ranges.

These additional features currently make the GX-4 non USGA-compliant, even though the extra information will only be displayed when using the bright-yellow faceplate/smart key. There is hope among some golfers that the USGA will approve this particular rangefinder for competitive play and we've seen reports of tournaments allowing the GX-4 without the smart key attached. But currently, from the information we have been able to gather, the GX-4 Rangefinder is not legal for all tournaments. For alternatives to the GX-4 that can be used all competitive golf situations, see both the GX-1 and GX-3 models.

PinHunter Technology & Prism Lock

At the heart of the Leupold GX-4 Laser Rangefinder is PinHunter and Prism Lock technology. Simply aim the crosshairs at your target (tree, flag, etc), and the GX-4 will send out a highly calibrated laser beam. When the signal is returned, the GX-4 will filter out any background noise and present you with an exact distance to the flag or hazard you are interested in.

Prism Lock technology makes finding the exact distance to the flag faster and easier than ever (so long as the flag makes use of a reflective prism). Put the flag in the crosshairs and in seconds the unit will lock in and return distance information.

TGR Feature

TGR, or True Golf Range, is made available by the GX-4 when you switch to the included yellow faceplate. Instantly, a wealth of additional information is made available to you based on factors such as slope, altitude, weather conditions, and more.  Not only do you get a distance reading, but the GX-4 will also give you an adjusted distance based on the aforementioned factors as well as your own particular swing speed and club distance averages.  

Another great advanced feature is the Club Selector technology. By taking distance information from 3 different clubs, the GX-4 will actually recommend clubs to use for particular shots based on the factors available. It's like having a personal caddy in your back pocket!

Scan & Fog Modes

Like all rangefinders in the GX series, the Leupold GX-4 also includes Fog Mode and Scan Mode.  

Fog mode was made for bad weather conditions. Most rangefinders fail in fog or light rain. The GX-4 Fog Mode feature allows you to receive accurate distance information regardless of inclement weather.

Scan mode means that you can obtain distances to a number hazards along with other objects in one, quick pass across the hole or green area. Simply deploy the power button and sweep over the area you are interested in. The LCD display will give live distance readings as you move the rangefinder view.

GX-4 vs. GX-2

The GX-4 and GX-2 both offer advanced features such as True Golf Range with slope, but only the GX-4 has smart-key technology. In addition, the GX-4 includes an aluminum body with rubberized grip (compared to the plastic body of the GX-2). The final major difference is the display. While the GX-2 makes use of an LCD display, the GX-4 utilizes an OLED screen offering easy and bright, brilliant red readouts.

Sample Customer Reviews

Reviews of this rangefinder are excellent with over 90% of all owners rating it as 4 stars or more (out of 5).

Positive Customer Reviews

This the best rangefinder I've ever owned (on my third). Club selection feature is very useful. It's extremely accurate and dependable.  I use it at the range all the time and distance numbers are right on the money every time.
--C.C.

The last time I purchased a rangefinder was a few years ago and I was highly disappointed. Decided to give the GX-4 a try and I'm simply blown away by both the accuracy and the features. It seems to be extremely well made and durable.
--J.K.

The bright red OLED display is worth the extra cost over the LCD screens which I find impossible to read sometimes.
-- P.B.

Negative Customer Comments

For longer distances, you'll need to lean against the cart or another solid object to prevent shake. Otherwise, it works great, especially from 200 yards in.
