Leupold GX-4i2 Review

Leupold GX-4i2 (8)

50 Words or Less

The most complete laser rangefinder available.  The only laser with the ability to switch between tournament-legal and slope modes.  A caddie’s worst nightmare.


As a former caddie, I feel like I should hate the Leupold GX-4i2.  Why?  Because outside of carrying the bag, the GX-4i2 does everything a caddie does.  The GX-4i2 adjusts for slope, temperature, and altitude and recommends a club.  How’s a guy supposed to get a loop competing with that?

Ease of Use & Set Up

In tournament mode (silver faceplate), the GX-4i2 is as easy to operate as the Leupold GX-3i2: push the button, get your yardage.

Attaching the yellow faceplate activates the slope feature, and you can simply use it like you would in tournament mode.  However, to get the full GX-4i2 experience, there’s a little more set up to be done.  First, to take advantage of the Club Selector feature, you’ll need to input your yardages for a few clubs.  Additionally, at the start of the round, you can input your altitude and temperature to take full advantage of Leupold’s True Golf Range (TGR) feature.  In total, this process doesn’t take more than a minute or two.

Accuracy & Performance

Let me start by quickly running down some of the features that the GX-4i2 shares with the GX-3i2.  First, the construction is the best you’ll find.  The body is milled from aerospace-grade aluminum and will stand up to any amount of dropping, tossing, and smashing.  The optics are unbelievably clear and the red display is easy to see in any light condition.  The yardages are accurate to the tenth of a yard and are delivered in a fraction of a second.

Now, let’s get into what separates the GX-4i2: slope and True Golf Range.  The slope mode requires no additional work, just attach the yellow face plate and shoot your target as you normally would.  Your display will show both the slope-adjusted and line of sight yardages.

When you activate True Golf Range, the GX-4i2 gets even more accurate.  You’re able to input both the temperature and the altitude, which the GX-4i2 will take into account when delivering the adjusted yardage and your club recommendation.  This is invaluable to players who travel and play courses at varying altitudes.  The amazing part is that these additional factors don’t slow down the GX-4i2 at all: push the button and all the info displays instantly.

The Leupold GX-4i2 laser rangefinder retails for $500.  This is the same as every other manufacturer’s top-of-the-line rangefinder with slope, but only the Leupold GX-4i2 offers both slope and tournament modes in one laser.  Additionally, the altitude and temperature adjustments and Club Selector feature are unique to the GX-4i2.

Like the GX-3i2, the Leupold GX-4i2 is weatherproof and has a two year warranty.

Final Thoughts

For the serious player, or any player who wants every possible advantage on the golf course, the Leupold GX-4i2 is the best laser rangefinder available.  The True Golf Range adjustments account for every factor except wind, and the ability to make the GX-4i2 tournament-legal makes it a great value.

    I have a Leupold4i and it is not working. I replaced the battery and when I tried to shoot the pin at my country club, it would show that the devise was searching for the pin, but no numbers came up. I tried it on four different holes and none showed a distance. What do I need to do to get it fixed?
