Leupold GX-4i2 Review

The Leupold GX-4i2 Rangefinder has it all starting from fully multi-coated optics, illuminated OLED Plus Point display, and Digitally Enhanced Accuracy (DNA) Golf to PinHunter Laser Technology, Fog Mode, and Prism Lock Technology. But, the real stunning feature lies in the True Golf Range and Club Selector features thanks to the interchangeable face-plate system.

If you can’t help your attraction to Leupold’s GX-4i2 laser rangefinder, then you really should fire your caddie now. For a one time cost of around $400, your caddie has been permanently replaced.

With several dozen reviewers reporting their experience with the new rangefinder, it’s raking in a solid rating. Now you know exactly what you’re getting yourself into when you walk down the aisle to the 4i2.

Leupold’s GX-4i2 Rangefinder Q&A:

Can the 4i2 calculate angle compensation shots?

Yes, and it can do way more than that. The GX-4i2 is Leupold’s slope edition rangefinder that can tell you exactly what you need to do and how far you need to go since it’s never a straight line to the hole. The slope technology that Leupold uses is called True Golf Range (TGR) and is more than capable of going the extra mile.


What is the yellow Smart Key that comes with the GX-4i2?

Be prepared to be overwhelmed – in a good way. The Smart Key is new technology that takes the original GX-4i rangefinder to a whole new level.

The newly improved rangefinder comes with an interchangeable exterior faceplate that allows and restricts the use of features depending on which faceplate is installed.

The smart key is the yellow faceplate that activates several features to personalize your golf game. These features include the inclinometer and club selector, as well as the option to manually input the temperature and altitude.

Are you ready to fire your caddie yet?


Is the rangefinder tournament legal even with all these features?

Yes. I’m not kidding. Although it sounds like a trick answer, it’s the truth. By replacing the yellow smart key with the chrome faceplate, your extra features will be disabled and your rangefinder is now tournament legal.

Why? Well… the chrome plate is USGA permissible and allows your unit to be legally used during tournament play since you’re no longer able to access slope technology and additional tournament illegal features. Where does that leave the older version? In the dust.

The GX-4i doesn’t have the luxury of being able to switch between the two worlds.


Does it have a club recommendation feature?

Just like hunting rangefinders have ballistic and ammunition settings and recommendations, it makes sense that a good golf rangefinder should have a club recommendation feature.

By entering in your average shot distances for the 4, 6, and 8 irons, as well as the temperature and altitude, the GX-4i2 can then do the arithmetic to give you best selection possible.

The display will recommend the club you need after you’ve depressed and released the laser firing button when ranging a distance. It’s also nice that you can turn the club recommendation feature off for when you’d rather not use it. That way, maybe your caddie might still have a job.


Is this rangefinder considered an affordable unit?

The GX-4i2 is Leupold’s premium golf laser rangefinder and so it’s not considered a budget-friendly rangefinder. In fact, at full cost around $625, it’s one of the most expensive in the market.

You can find it for around $480 though (Leupold golf rangefinder best price), which is still dramatically cheaper than the GX-3i2 at full cost. If you were to compare the GX-4i2 to other brand premium rangefinders, it falls in the same price category.

But… there’s always a but. The interchangeable faceplate and the club recommendation feature with the upgraded PinHunter 2 and Prism Lock technology certainly justify the higher price.


Noteworthy Features:

  • Revamped DNA technology for even more precise and faster readings
  • PinHunter 2 and Prism Lock Technology for zeroing in and locking onto the flag
  • Fog Mode to range through the toughest weather
  • Interchangeable faceplate with Smart Key to access slope technology and other features
  • Club recommendations works with TGR technology for best shot
  • Can input temperature and altitude values
  • Scan Mode available
  • 3 different reticles to choose from
  • Scratch-proof lens with low glare for clear and bright images


Our Verdict on the GX 4i2

To ping up the strokes, Leupold joins the interchangeable face plate system that golfers are ecstatic about. While being legal for tournaments, you can also practice with the slope plate to prepare for the big day.

In comparison, the GX-5i3 happens to be the best of Leupold’s rangefinders. Of course the price is going to reflect this, but without having to deal with changing out face plates like you do with this 4i3, the new 5i3 can be easily made tournament legal with a push of button.

When sticking with the best, Leupold pleases the golfing crowd pretty well. You may just be right to pay extra and stay loyal
