Callaway 300 Pro Golf Rangefinder Review: Features & Benefits

Callaway pro 300

Impressive Range With Enhanced Accuracy

The Callaway 300 Pro features an LCD display with 6X binocular zoom and a range of 1000 yards. You can accurately read the course for even the toughest of Par-5s or the longest holes as you lower your handicap.

This impressive range with enhanced accuracy optimizes the performance of the 300 Pro Golf, where no matter the terrain, range, or skill level, you can expect precise reads above all else.

Slope Adjustment

Slope not only affects your swing’s kinematics and output but also your ball’s spin and the accuracy of your lie. You’ll need to know what you’re up against, as even the slightest change in elevation can hurt your stroke, accuracy, and overall score.

The Slope Adjustment takes the inherent accuracy of the 300 Pro up a notch, where your rangefinder automatically adjusts to slope settings, whether uphill or down. Even with the slightest elevation change, the Callaway Rangefinder 300 has covered you, ensuring your hold is secure and your swing stays sharp even at the steepest angles.

I found this feature especially helpful. This tech is a lifesaver for courses with many green bumps or harder-to-read slope changes.

Moreover, the Slope Adjustment has an external on-off switch, making it legal for tournament play.

Pin Acquisition Technology (P.A.T)

The state-of-the-art P.A.T engineering can lock onto your desired pin from up to 300 yards away. With the P.A.T design, you’re given an exact measurement down to a minuscule +/- 1 yard, the standard across most rangefinders you’ll find at play in the golfing world.

I’d recommend honing in on the flag rather than the pin, as most courses put a reflector strip or some form of indicator for rangefinders on their flags to make more accurate reads.

To use the P.A.T feature, simply aim your rangefinder at the flag and press the power button. After you’ve powered on, and if you’re in birdie mode, you’ll hear an audible chirp, an indicator that makes great scoring that much more exciting.

After you’ve heard the bird, you’ll be given 2 numbers: the first being the true distance and the second being with the adjusted slope change. Once you’ve achieved the same numerical reading–and with the birdie sound—a couple of times on the same target line, you’re good to fire away.

The precision of the +/- 1-yard reading paired with the 300 Pro’s audible indicator and simplified, the 2-number display makes P.A.T shots easy and full of confidence; you’ll notice an immediate difference in just how calm, cool, and collected you’ll feel approaching the pin.

Look, Feel, & Durability

Coming in at only 4” wide and less than 2” high, this compact rangefinder will surely fit in any golfer’s bag regardless of space constraints. This is also a lightweight, sleek rangefinder that’s up there with other contemporary, stylish models, with the Pro featuring a stripe of polished crimson.

I found the rangefinder well proportioned and thoughtfully designed when using it, as you can fix the Pro to most other rangefinder holders that magnetically fix to your cart or club. If that’s not enough, the Magnahold magnet can fix itself to any magnetic part of your cart effectively.

What’s more, the case for the 300 Pro is a nice touch as it comes with its own hard-shelled case that provides additional protection from damage.

Water & Fog Proof

Not only does moisture affect all areas of your golf performance, it certainly can do a number on your equipment, causing warping to your clubs over time or simply short-circuiting your electronics well before their lifespan.

Luckily, the 300 Pro has a water-resistant outer casing that protects your rangefinder from fog, water, or otherwise damaging moisture buildup. This protective casing makes the Pro suitable for all playing conditions, whether sunny and 70° or a foggy 7 AM tee time.


With your purchase, you’re getting an additional, powerful V3 battery and charger thrown into your purchase bundle; the Callaway will certainly be—and last as—your favorite rangefinder for many reads to come.

Callaway backs the 300 Pro with a limited, 2-year warranty if that isn’t enough.

Things To Consider Before Buying The Callaway 300 Pro Rangefinder


During extensive play-testing, I found that operating the 300 Pro tended to be a little slower than other rangefinders I’ve used, especially when locking on focuses.

Tree Interference

When playing on a course with taller trees near the pin, we found that the 300 Pro had trouble locking onto a given target. Usually, the system will climatize and work itself out, but the distance read’s accuracy may be affected.


The 300 Pro’s lack of stabilization tech may provide you with the occasional inaccurate read, especially if your hands are unsteady.

That said, if you’re careful and steady when locking onto your reads, you’ll get plenty of helpful, game-improving data back.


Does Callaway 300 Have Slope?

The Callaway 300 does have slope with slope detection technology that automatically adjusts for a given course’s slope down to the slightest change in elevation. For high handicappers or golfers looking to read and predict lies accurately, this is a critical feature for your success and, in turn, lowers your score.

Does Callaway 300 Pro Have Magnet?

The Callaway 300 Pro features an integrated Magnahold™ magnet that works to quickly affix your rangefinder to your cart with a secure hold. For golfers that prioritize speed and efficiency in their equipment, this is a must to keep your rangefinder handy and in the spirit of ease of access.

How Do I Change My Callaway 300 Pro To Yards?

You can change your Callaway 300 Pro to yards by firstly powering on your rangefinder via the external power button. From there, hold down on the “mode” button where a visible Y for yards and an M for meters is displayed. Select Y for yards, and voila, it’s just that easy.

Final Thoughts

With our Callaway 300 Pro Review, we set out to determine the functionality of the Pro by weighing its build, durability, tech features, and just how precise a reading it delivers. The 300 Pro rangefinder is all that and a bag of chips.

With accuracy down to +/- 1 yard and a powerful 1000-yard range paired with its cutting-edge slope advance tech and pin acquisition engineering, the 300 Pro Golf Laser Rangefinder is a weather-resistant, precise tool for golfers looking to be better and improve their game.
