Golf rangefinders are used to measure distances on a golf course. They can be laser-based or GPS-based, and some can even be used with GPS. To find the distance to the hole, golfers aim the rangefinder at the flag and click a button to hone in on the target. The rangefinder then calculates the distance based on the time it takes for the laser beam to bounce off the target and return. While rangefinders are legal in most tournaments, the slope feature, which calculates the yardage of a shot that might be uphill or downhill, is not permitted during tournament play.
| Characteristics | Values |

Laser rangefinders calculate distance by measuring the time taken for a laser to bounce off a target
Golf rangefinders are used to measure the distance to a specific target, such as the flag, a hazard, or the front or back of the green. Laser rangefinders work by measuring the time it takes for a laser beam to bounce off a target and return to the device. This time measurement is then used to calculate the distance to the target.
Laser rangefinders offer a high level of precision, providing measurements down to the yard or even a tenth of a yard. This level of accuracy is particularly advantageous in golf, where distance plays a crucial role in club selection and shot strategy. By knowing the exact distance to the target, golfers can make more informed decisions about which club to use and how to execute their shots.
The process of using a laser rangefinder is relatively simple. The user aims the device at the desired target and clicks a button to activate the laser beam. The laser beam travels towards the target, reflects off it, and returns to the rangefinder. The device then calculates the distance based on the time taken for the laser to make this round trip.
Some advanced rangefinder models offer additional features, such as slope calculation, stabilization for shaky hands, GPS integration, and wind readings. These features further enhance the user's understanding of the course and can provide valuable insights for strategic decision-making.
It is important to note that while rangefinders with slope calculation can provide highly precise yardages, this feature is typically prohibited during tournament play. Slope-adjusted distances can significantly influence club selection and shot strategy, taking into account the elevation changes between the golfer and the target. However, in most tournaments, players are required to turn off the slope feature to comply with the rules.

Rangefinders with slope features are not allowed in tournaments
Golf rangefinders 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, on the other hand, allows caddies to use rangefinders. The slope feature, which adjusts for hills, is not permitted during tournament play, although it is difficult to enforce among casual golfers.
Some rangefinders have a physical adjustment, such as swappable faceplates, to switch between slope and no-slope modes. Other rangefinders have a button or switch to disable the slope feature. It is important to check the tournament rules and the rangefinder manual to ensure compliance.
While non-slope rangefinders are better suited for tournaments, slope rangefinders can be beneficial for practice or casual games. They improve accuracy, especially on hilly courses, and help golfers build confidence by providing precise distance measurements. When choosing a rangefinder, it is essential to consider features such as slope switches, battery life, and clear displays.

GPS devices are less precise than rangefinders
Golf rangefinders use laser technology to measure distances to specific targets on the course. They are typically handheld devices that are easy to carry in your golf bag or pocket. To find your distance to the hole, you aim the rangefinder at the flag and click on one of the buttons on top to lock in on the target. The rangefinder then measures the time it takes for the laser beam to bounce off the target and return to the rangefinder, then calculates the distance based on that time. Rangefinders are known for their accuracy, and they can provide precise distance measurements to specific targets on the course.
GPS devices, on the other hand, calculate their position by measuring their distance from multiple GPS satellites. While GPS devices have their advantages, they are generally less precise than rangefinders, especially in situations with weak or inconsistent signals. GPS devices also don't account for slope, whereas many golf rangefinders provide distances that take slope into account. This can make a significant difference in club selection for certain approach shots. Additionally, GPS devices are limited to pre-programmed course maps, whereas laser rangefinders can be used on any course by focusing on a target to get a measurement.
The accuracy of GPS devices is also affected by factors outside the government's control, such as satellite geometry, signal blockage, atmospheric conditions, and receiver design features. While civilian GPS devices typically use only one GPS frequency, military receivers use two, which improves accuracy by correcting signal distortions caused by the Earth's atmosphere. Although dual-frequency GPS equipment is available for civilian use, its cost and size have limited its application to professional use cases.
In summary, while both GPS devices and golf rangefinders have their advantages, GPS devices are generally less precise than rangefinders due to factors such as signal strength, course map limitations, slope calculation, and external factors affecting accuracy. If precision is a priority, a golf rangefinder may be the preferred choice.

Rangefinders are now legal in most golf competitions
In 2019, an amendment to The Rules of Golf allowed the use of rangefinders, but only to give information on distance and direction. Measuring elevation changes with a rangefinder was not permitted. This rule change paved the way for the integration of rangefinders in the professional game. According to the Rules of Golf, laser rangefinders are allowed to be used in competitive PGA championships by professional golfers. The golfers are permitted to use these devices to measure distance but not to calculate the true distance when playing on a slope.
The LPGA Tour also allows caddies to use rangefinders on the course. However, the PGA Tour, Korn Ferry Tour, and PGA Tour Champions do not permit the use of rangefinders during their events. While the men's professional game has been slower to embrace this technology, there are signs of a shift towards acceptance. For example, in 2022, LIV Golf announced that distance-measuring devices would be permitted during their Team Championship tournament.
Rangefinders have become increasingly popular among golfers due to their accuracy and efficiency in measuring distances. They work by measuring the time it takes for a laser beam to bounce off a target and return to the device, then calculating the distance based on that time. This technology provides quick and precise yardages, aiding golfers in estimating distances and improving their swing.

Rangefinders can be steadied by placing the elbow against the chest or on a surface
Golf rangefinders are used to measure the distance to a specific target, such as the flag, a hazard, or the front or back of the green. They work by measuring the time it takes for a laser beam to bounce off the target and return to the rangefinder, and then calculating the distance based on that time. This provides golfers with precise data to determine the appropriate club for each shot.
To get the most accurate reading, it is important to keep the rangefinder steady when taking a measurement. One way to do this is by placing the elbow of the raised arm against the chest. This provides stability and helps to keep the rangefinder still while aiming and clicking the button to initiate the laser beam. By pressing the rangefinder against the chest, the golfer can create a stable base and minimise any shaking or movement that could impact the accuracy of the reading.
Another technique for stabilising a rangefinder is to use both hands when holding the device. This can help to distribute the weight more evenly and reduce any shaking or movement caused by an unsteady grip. Using both hands can also make it easier to keep the rangefinder level and properly aligned with the target, which is crucial for accurate measurements.
In addition to using the body for stabilisation, golfers can also utilise solid surfaces such as a golf cart. By resting the elbow or elbows on a sturdy surface, golfers can further minimise any unwanted movement of the rangefinder. This technique is especially useful when taking measurements over a longer period, as it can help reduce fatigue in the arms and hands, leading to more consistent readings throughout the game.
While some golfers prefer to hold the rangefinder with their hands, using a solid surface can provide a more stable platform and improve accuracy. It is important to note that the surface should be solid and stable to ensure the rangefinder remains steady during the measurement process. By employing these techniques and utilising the features of their rangefinder, golfers can improve their accuracy and make more informed decisions on the course.
