First Hand Experience on The Golf Course

Using the Callaway 300 Pro Rangefinder on the golf course has been a game-changer for us. As we used the rangefinder on the course, we made sure to test the features that Callaway showcased for this device.

FIrst of all, the ease of use stood out right away. With its light weight of just 7.5 ounces, we can easily carry it in our pockets. Being able to attach the rangefinder to the golf cart with its built-in magnet was a game changer as well. No more needing to dig for the device in the cubbies of the golf cart or stowing it away in the bag. 

From a performance perspective, the rangefinder delivered pin-seeking accuracy consistently and easily. When targeting the flagstick on the green, the device locked on quickly and precisely. We retried the distance read to see if the read was consistent and we’re happy to report that the rangefinder stayed true to the distance it displayed.

For some of the more hilly holes during our round, we sought to see how the slope technology adjusted the yardage. The slopes were read accurately and helped us account for the added distance of slopes as we approached the green with our irons. 

To test out magnification, we put it to the test on the par fives on the course. On a straight par 5, we took out the rangefinder to get a read on distance to the flag with the rangefinder and compared it with the scorecard distance. The rangefinder was nearly spot on give or take a few yards. 

One of the features we appreciate most is the vibration feedback. When the rangefinder locks onto the flagstick, it gives a slight vibration. We never had to guess when the rangefinder measured the distance.

The scan mode is also useful, allowing us to sweep across the landscape and get multiple distances quickly. By holding down the button to read distances, we were able to easily scan across the fairway or green to see the different distances to various locations of the hole.

Comparison Among the Competition

When comparing the Callaway 300 Pro Rangefinder with its competitors, several factors stand out.


The Callaway 300 Pro is reasonably cost-effective when compared to some of the other rangefinders on the market. For example, Bushnell rangefinders are often at a higher price point, offering additional features but at a significantly higher cost. Consider what features are most important to you in a rangefinder before you decide to spend more or less money on one.

Rangefinder ModelPrice RangeNotable Features
Callaway 300 ProAffordableSlope feature, accuracy
Bushnell Pro XEHigher priceAdvanced optics, durability, wind speed and direction
Nikon Coolshot Pro IIMid to high priceHigh accuracy, clear display

It is worth knowing that the features between the Callaway 300 Pro and the Nikon Coolshot Pro II are virtually identical with slight differences in the design. The price points can vary between $100 to $150 dollars between the two, making the Callaway 300 Pro a viable option without leaving out features. Be careful to read the features that each rangefinder includes so that you can ensure you’re getting the biggest bang for your buck.


Our experience using the Callaway 300 Pro Rangefinder has been a delight. This rangefinder is a reliable tool for golfers seeking accurate reads and is effective in aiding course management and making better shots. The confidence that a good rangefinder can provide when choosing your shot can go a long way in helping you play better.

At its price point with the features included, we give high marks to the Callaway 300 Pro Rangefinder for what it does. We highly recommend golfers consider this rangefinder when looking for the right one for you.
