A few golfers reported a delay in calculations


The importance of possessing a reliable rangefinder is no longer a subject of a debate as it is more than clear that the correct measurement will provide golfers with required information that will help them make multiple decisions such as which club to select or how powerful their swing needs to be. There are different types of rangefinders, from basic ones that deliver information on the distances to the pin or selected target to more to those that calculate slope distances and scan the area. In addition to offering multiple features, what makes the rangefinder attractive is the good grip, ergonomic design and the compact size which will allow golfers to have it all the time with them.

In line with this, Callaway makes one of the most lightweight distance finders on the market, and even though this is not the smallest and the lightest, it is very compact, sleek and ergonomic, weighing only 7 oz. The surface provides good grip and rough surface so that it doesn’t easily slip, especially when the weather is rainy.


Callaway rangefinders are easy to use as the designers focused on convenience and practicality as the first guiding principle when constructing it. However, due to the fact that there are several functions, it is advisable to read the user manual for further reference, in case you are not quite sure how it works.

Anyway, we will try to make things easy and simple for you, and describe the functions and how to activate them. To measure the distance to the selected target, you will need to press the power button, and the crosshairs will come up to provide you the distance to the selected target. When measuring the distance to the flag, you should point to the flag pin and wait for the correct measurement which is delivered in a second. To go through different modes, you should press the mode button which also selects whether you’d like to have the measurements in yards and meters.

One of the top features that Callaway 300 has is the slope function which is activated by sliding the side button up and down for enabling, i.e., disabling it. Plus, the scan mode delivers the distance to different targets such as trees, water hazards, or greenside bunkers. To activate this function you need to press scan mode and aim to the location that needs to be scanned. You will have the locations displayed on the screen by pressing the black button for each of the selected objects.


Callaway 300 Pro is more advanced rangefinder that besides the basic features, it provides golfers with precise measurements to the pin, to the target, and it also scans the area to provide the distance to multiple objects. Plus, it features slope measurement function and the company's Pin Acquisition Technology (P.A.T) that allows golfers to get the distance to the pin from up to 300 yards even in situations when the surrounding is not clear and when there are many trees or objects in the background. What makes this rangefinder very convenient to use is the “birdie” technology that makes the device chirp like a bird once it locks onto a flag.

Slope Measurement Technology

Golf courses are not flat surfaces and some multiple inclines and declines can affect the measured distance to the flag and the other targets. Therefore, the Slope Measurement technology has been invented to measure the inclines and declines to calculate the slope adjusted distance. However, this function is not in accordance with the USGA regulations and the terms of use, so it is forbidden to be used in legal tournaments. This is the reason why there is an on/off button that turns this function on and off.


Golfers need rangefinders to get precise distance measurements, so in case the rangefinder delivers incorrect measurements it would be pointless to use it. Fortunately, Callaway 300 Pro is one of the most accurate rangefinders on the market, with an accuracy of +/- 1 yard that is the maximum precision that equals the premium ones. The range to measure distances spans from 5 to 1000 yards with a bit of instability characteristic for more distant targets. The time that is needed to calculate the distance is considerably fast, however, some golfers noticed that it needs reestablishing the distance during bad weather conditions. Thanks to the “birdie” function, every time the target to the pin has been locked, you will hear a chirping sound.

Zoom and Optics

When it comes to lens quality, in this model we can see Callaway superiority in the brightness and the clearness of the lens, helping golfers clearly see the targeted object and make an adequate decision on which club to use. Regarding the possibility of bringing the images closer to a golfer, Callaway 300 offers 6x magnification to allow golfers to magnify the landscape and the targets and get a clearer image of the most further objects. Golfers claim that having been able to use this feature, has provided them with a crisper image of the landscape or to easily locate the pin. To zoom in, you need to rotate the rubber eyepiece which is located at the lens point of the device.


The quality of the display is significant since it allows golfers to see the target which will help them make important decisions on their strategy, such as the type of the club and how they are going to perform each shot. Callaway 300 Pro features a premium LCD screen to deliver high definition images helping you to see what’s ahead and make suitable choices. What golfers can read on the LCD display is the yardages or the meters to the target, status of the slope function, PAT mode indicator when it is turned on, and the status of the battery.

So far, we have discussed the basic features and technologies that mark the performance of this distance finder.
