Golf scopes, also known as rangefinders, are used to determine the distance to a target on a golf course. They can be laser-based or GPS-based. Laser rangefinders work by bouncing a laser off the target to measure the distance, while GPS devices provide distances to the front, middle, and back of the green. Rangefinders are generally more accurate and may offer additional features such as slope adjustments, which calculate the yardage of a shot by taking into account elevation changes. While slope adjustments are not allowed in tournament play, rangefinders are permitted in casual play and most tournaments, except for the PGA Tour, Korn Ferry Tour, and PGA Tour Champions.

What You'll Learn
Rangefinders vs. GPS devices
Golf scopes, or rangefinders, are devices that use laser technology to measure distances to specific targets on a golf course. They emit a laser beam towards a target, such as a flagstick, and when the laser hits the target, it reflects back to the rangefinder. The device then measures the time it takes for the laser to travel to the target and back, calculating the distance based on this time interval.
Now, when it comes to choosing between a golf rangefinder and a GPS device, there are several factors to consider. Both have their own unique advantages and disadvantages, and the choice ultimately depends on personal preference and playing style.
Rangefinders are known for their accuracy and precision. They can provide exact yardage information, even down to the yard, and modern ones have features like slope compensation, which calculates the distance adjusted for changes in elevation. They are typically handheld devices that are easy to carry in your golf bag or pocket. However, they may be more cumbersome to use as you have to take them out and point them at your target each time you want a distance reading. Additionally, rangefinders only provide distance measurements and do not offer additional course information such as hole layout or hazards.
On the other hand, GPS devices use satellites to provide golfers with distance information and comprehensive course details, including hole layouts, hazards, and even shot tracking. They can be handheld devices or wearable watches, with the watch option providing quick yardage information at a glance. GPS devices are also advantageous when you cannot see your target as they do not require a clear line of sight. However, they tend to be more expensive than rangefinders, and additional subscription fees may apply. GPS devices may also be less accurate, especially in situations with weak or inconsistent signals.
Some golfers choose to use both devices, utilising the rangefinder for approach shots and the GPS device for hole layout information. It is worth noting that while rangefinders are allowed in casual play and most tournaments, they are not permitted on the PGA Tour, Korn Ferry Tour, and PGA Tour Champions.

Laser rangefinders
Rangefinders are compact, ergonomic, and easy to store, fitting seamlessly into your golf setup. They can be conveniently carried in your pocket or mounted on your cart with a magnetic mount. Some models also integrate golf GPS, offering both laser precision and course-wide insights. This combination provides exact distances with a line of sight and key yardages when your view is blocked.

Legality in tournaments
Golf scopes, also known as rangefinders, are used to measure the distance between the player and the hole. They are more precise than GPS devices, which only give distances to the front, middle, and back of the green.
The legality of using rangefinders in tournaments depends on the specific tournament and its guidelines. While rangefinders are generally allowed in casual play, they may not be permitted in certain tournaments or competitions.
For example, the PGA Tour, Korn Ferry Tour, and PGA Tour Champions do not allow the use of rangefinders. On the other hand, the LPGA Tour allows players' caddies to use rangefinders on the course.
According to Rule 4.3a, rangefinders are allowed in some tournaments, but not all of their functions may be permitted. For instance, the slope feature, which calculates the yardage of a shot considering uphill or downhill angles, is not allowed in any tournament and must be turned off during tournament play.
It is important to note that local rules may also come into play, and it is always a good idea to check the specific guidelines of the tournament in question. While some tournaments, like the U.S. Amateur and U.S. Junior Amateur, allow competitors and caddies to use rangefinders (without the slope function), others, like the Open Championships, forbid their use entirely.
The PGA has allowed the use of laser rangefinders in their championships to promote consistency with the Rules of Golf and to add an element of fun to the game. However, some professional golfers still prefer conventional methods of determining distances due to their extensive experience in estimating distances during play.

How to use a golf scope
Using a golf scope, or rangefinder, is a simple process. Firstly, ensure your device is charged and has plenty of battery life. Check your user manual to understand the specific functions of your device, as each brand of rangefinder is different.
Once you are on the course, you can start using your rangefinder. Aim the device at your desired target, such as the flag, a hazard, or the front or back of the green. You can use your rangefinder to aim at anything and see how far away it is. You will get the best accuracy if you have a steady hand, so aim at larger targets. Some flagsticks have reflective material that makes them easier to target, and some rangefinders will vibrate when they lock onto a target. You can also keep your rangefinder steady by placing your elbow against your chest or resting your elbows on a solid surface.
After aiming, simply press a button and look through the eyepiece. The rangefinder will give you the yardage to your target. More advanced models can also provide information like the slope, which can be crucial during a round of golf. These models will measure the actual yardage and then calculate the yardage of the shot, taking into account whether it is uphill or downhill.
It is important to note that while rangefinders are legal for casual play and most tournaments, the slope feature is not permitted during tournament play according to US Golf Association rules. Remember to turn off this feature if you are using your rangefinder during a tournament.

Slope adjustments
Golf rangefinders are devices that use lasers to determine the distance to a target. They are useful for golfers who want to know the distance to the middle of the green. While some golf courses have markers that indicate the distance, most golfers nowadays use measuring devices such as GPS or laser rangefinders.
Rangefinders will always give the actual yardage, but some more advanced models can also provide the slope, which is the change in elevation between two points. This feature is called slope adjustment, and it gives golfers an adjusted distance to aim for, taking into account whether they are hitting uphill or downhill. This adjusted distance helps golfers choose a club and know how hard to swing.
For example, if a golfer is on a tee box and the green is 150 yards away but also 48 feet above them (a 6-degree incline), their rangefinder will give a reading of 152.6 yards. With the angle compensation turned on, the rangefinder will return 150 yards, the horizontal distance. If the golfer turns on the slope adjustment, the device will return 166 yards for an uphill shot and around 140 yards for a downhill shot.
It is important to note that the slope adjustment does not consider the trajectory of the shot. When adjusting for the slope, golfers should lean with the slope so that their pelvis and shoulders match it. They should also consider using a more or less lofted club and adjusting their stance to account for the slope.

Frequently asked questions
A golf scope is a device that helps golfers estimate the distance to the flag from 50 to 200 yards/meters.
Unlike laser rangefinders, which provide distance readings at the push of a button, golf scopes require the user to estimate distances to the flagstick on their own.
While the device is straightforward to use, obtaining accurate readings can be challenging. The accuracy of the distance reading depends on how good the user is at keeping their hands steady and estimating distances.
Laser rangefinders are more accurate than golf scopes, but they are also more expensive. Laser rangefinders can be aimed at anything and show how far away it is. Golf scopes are best for those who want to know distances but don't want to spend a lot of money.
Golf scopes are legal in casual play and for most tournaments. However, the PGA Tour, Korn Ferry Tour, and PGA Tour Champions do not allow them. The LPGA Tour allows players' caddies to use them.
