Callaway 300 Pro Golf Laser Rangefinder Review – 2022 [Slope Measurement ]

There are a lot of golf rangefinders on the market these days. So, how do you know which one to buy? If you’re looking for the most advanced and accurate golf rangefinder on the market, then you should definitely consider buying the Callaway 300 Pro Golf Rangefinder.

This Callaway 300 Pro Golf Laser Rangefinder Review will go in-depth into what makes this product so special to help you decide if it’s worth purchasing or not.

What is the Callaway 300 Pro Range Finder?

The Callaway 300 Pro is a golf rangefinder that uses laser technology to measure the distance to objects. It has a built-in display that shows the range in yards or meters, and it also has a feature that allows you to adjust the measurement for the slope of the terrain.

The Callaway 300 Pro laser golf rangefinder is powered by a CR2 battery that provides up to 20,000 measurements.

What to Look for in a Rangefinder?

When looking for a rangefinder, there are a few things to keep in mind. First, what is the intended use? If you’re looking for a rangefinder to use while playing golf, then you’ll want to make sure it has yardage capabilities and is able to be mounted on a golf cart. If you’re just looking for a general-purpose rangefinder, then battery life and magnification might be more important factors.

Laser rangefinders are generally more accurate than GPS units, but they can be more expensive. If you’re looking for a budget-friendly option, then a golf GPS unit might be the way to go. Just be aware that they might not be as accurate as a laser rangefinder.

Easy to use is an important factor no matter what your intended use is. You don’t want to be fumbling around with buttons while trying to take a measurement. And finally, if you’re going to be using it for golf, make sure it has slope measurement capabilities.

One of the best features of the Callaway 300 Pro Golf Rangefinder is its superior accuracy.

This rangefinder uses a laser to measure distances, and it is incredibly accurate. In fact, it is so accurate that you can use it to measure the distance between two points on a golf course within one yard.

The Pin Acquisition Technology (PAT)

Patented Pin Acquisition Technology (PAT) from Callaway is a real game-changer for new and experienced golfers alike.

This technology allows you to lock onto the pin at precise distances up to 300 yards with an accuracy of ± 1 yard without picking up any background objects that could interfere with your shots.

Whether you’re just starting out or looking to up your game, PAT provides the precision and confidence you need to make Every Shot Count.

Audible Jolt

This golf rangefinder got a little birdie feature, so it creates little audible confirmation when it acquires the lock on the flag. 

As you scan it’ll show you the different distances and makes a ‘chirp’ sound when you shoot the flag.

So its exclusive birdie feature delivers an audible chirp to confirm the distance acquisition to the flagstick.

It’s much like other rangefinders have vibrating jolt this offers an audible chirp sound like a bird if you just pick out the flag from the background. 

Slope Calculation

This Callaway laser rangefinder gives you slope adjusted distance, so you would know what degree you’re shooting it at, and gives the adjusted range. 

If you are shooting uphill, you need to choose the club which can hit a little farther and if you are shooting downhill, you need to choose the club which shoots a little shorter.

So the slope function is great to find out what kind of golf clubs you need to use. The slope feature measures the angle of incline decline and automatically calculates the slope-adjusted distance.

Callaway 300 Pro has an external slope on-off switch to make it tournament legal. You can turn off the slope while playing in a tournament.

Pin-Seeking Precision

The device uses its patented Pin Acquisition Technology.

This ensures that you always get the correct reading to the flag. It removes the focus from obstacles behind the flag.


This rangefinder features a massive range of up to 1000 yards, which you can see on the clear and easy-to-read LCD display.

It has 6x magnification, which helps you to get a closer look at the flagstick and other objects on the course.

This powerful magnification allows you to zoom in on flagsticks from very far away so that it’s simple to aim your shot even if the pin is tucked way back near other obstacles.

Multiple Targeting

Its scan mode allows you to acquire distances to multiple targets at once, this feature allows you to measure different distances on the course simultaneously. All the readings flash on the LCD screen as you scan an area.

Superior Magnification and Accuracy:

Its 6x magnification coupled with a 5 to 1000 yards range provides you with an impressive view. It can quickly lock onto the pin from up to 300 yards away.

The magnification power brings objects closer for proper identification and distance reading.

Fog and Water Proof:

The 300 Laser is both resistant to fog and water. It basically means you can use it during slight rain without an umbrella.

Despite this advantage, most of the best golf rangefinders do not work well during days with heavy clouds or at sundown.


Magnahold technology allows you to attach the rangefinder to a golf cart for easy access during your round. Its magnet is strong enough to hold it in place, but not too strong as to make the rangefinder hard to remove.

Slope On-Off Switch

This is a legal rangefinder for tournament play because it has an external slope On/Off switch. This setting makes it easy to toggle between non-slope and slope mode, which can be useful if you need the measurements to conform to different local rules of varying courses.
