Understanding Golf Rangefinder Technologies
Golf rangefinders come in three main flavors: laser, GPS, and optical. Each of these technologies offers unique benefits, making them well-suited for different situations and golfer preferences. In essence, all golf rangefinders work by measuring the distance between the golfer and targets on the course, but they achieve this through different means.
Let’s dive deeper into each type of rangefinder and explore how they work, their advantages, and their drawbacks.
Laser Rangefinders
Laser rangefinders are perhaps the most well-known type of golf rangefinder. They work by emitting an invisible laser beam aimed at the target, which then reflects off the target and back to the rangefinder. The device’s sensor detects the time it takes for the laser to return, and an internal chip calculates the distance based on this information. With typical range ratings of well beyond six hundred yards and accuracy within one yard, laser rangefinders are highly precise and versatile, allowing golfers to measure distances to any object on the course.
However, laser rangefinders do require more manual work than GPS models, as golfers must aim the device at the target to get a reading. Additionally, lower-priced models can struggle to lock onto the correct target or provide accurate readings, especially when there are trees in the background.
Some laser rangefinders are equipped with slope measurement technology, which adjusts the distance reading based on the angle of the terrain, but this feature may not be tournament legal.
GPS Rangefinders
GPS rangefinders offer a more automated solution to distance measurement on the golf course. They use satellite signals to triangulate the golfer’s position in relation to targets on the course. While not as accurate as laser rangefinders, GPS models still offer impressive accuracy within a few feet.
GPS rangefinders come in two main styles: handheld devices and golf GPS watches, giving golfers the flexibility to choose the format that best suits their needs. The primary advantage of GPS rangefinders is their reliance on satellite mapping, which allows golfers to measure distances without having to aim the device at a target. This can be especially helpful when the target is obstructed by trees or other objects on the course.
The downside to this however, the GPS does not know pin location. So your reading will be a general front, middle, or back of green distance.
GPS rangefinders typically require a monthly subscription fee for satellite signal use, and golfers must ensure that their device has the necessary course maps loaded before use.
Optical Rangefinders
Optical rangefinders represent the analog side of distance measurement in golf. These devices use parallax to determine distance based on the height of an object. Equipped with two lenses at one end, optical rangefinders magnify the target to determine its height, and then use an integrated scale to calculate the distance. Although not as accurate as laser or GPS rangefinders, optical models are a reliable and time-tested option for golfers who prefer a more traditional approach to distance measurement.
However, the main drawback of optical rangefinders is their limited accuracy compared to their laser and GPS counterparts. As such, they may not be the best choice for golfers who require the highest level of precision in their distance measurements. Nevertheless, optical rangefinders can still provide valuable insights on the course and may be a suitable option for those who prefer a more analog experience.
How Golf Rangefinders Help Your Game
By providing accurate distance measurements, rangefinders can greatly benefit a golfer’s game. With precise yardage information at their disposal, golfers can make better decisions about club selection and shot placement, ultimately improving their overall performance. In addition to helping with club selection, rangefinders can also assist golfers in navigating hazards and managing slopes on the course, further enhancing their ability to strategize and execute effective shots.
Slope Measurement
Slope measurement is a feature available in some rangefinders that calculates the degree of elevation between the golfer and the target, adjusting the distance measurement accordingly to provide a more accurate “play-like” yardage. This feature can be particularly helpful when playing on courses with significant elevation changes, as it allows golfers to account for the impact of the terrain on their shots.
To use slope measurement, simply activate the feature on your rangefinder and point it at the target. The device will then calculate the angle of the terrain and adjust the distance measurement accordingly, providing you with a more accurate yardage for your shot.
Keep in mind, however, that rangefinders with slope measurement may not be tournament legal, so be sure to check the rules before using this feature in competition.
Elements
It is amazing how far technology has come. Check out my review on the Bushnell Pro X3 rangefinder.
The Pro X3 has the ability to account for temperature and barometric pressure as part of its “adjusted” distances. So in addition to slope, it is also going to take the weather into account.
They didn’t stop there, you can even set your home course elevation, which is where you know your “normal” distances. Then if you travel to a course with a much higher/lower elevation, the rangefinder technology will adjust your distances providing you with what “your normal” looks like.
Although Bushnell introduced this technology into rangefinders, I don’t think it will be long before we start to see this throughout the rangefinder manufacturers.
Comparing Laser and GPS Rangefinders
Now that we’ve explored the workings of both laser and GPS rangefinders, it’s time to compare and contrast them in terms of accuracy, ease of use, cost, and features. While both types of rangefinders can provide valuable distance measurements to golfers, each has its own unique advantages and disadvantages, making them better suited for different situations and preferences.
In the following sections, we’ll delve deeper into the differences between laser and GPS rangefinders, helping you determine which type of device best suits your needs and preferences on the golf course.
Accuracy and Precision
When it comes to accuracy and precision, laser rangefinders have the edge over GPS models. With a typical accuracy of up to 1/10 of a yard, laser rangefinders provide highly precise distance measurements, making them the go-to choice for golfers who require the utmost accuracy in their yardage readings.
GPS rangefinders, on the other hand, offer slightly less accuracy, with readings typically accurate within a few feet. While this level of precision may be sufficient for many golfers, those who demand the highest level of accuracy may prefer the pinpoint precision offered by laser rangefinders.
Ease of Use and Convenience
In terms of ease of use and convenience, GPS rangefinders come out on top. Thanks to their satellite-based technology, golfers can obtain distance measurements without having to aim the device at a specific target, making for a faster and more seamless experience on the course. In addition, GPS rangefinders often come with pre-loaded course maps and other helpful features, further enhancing their user-friendliness.
Laser rangefinders, while offering superior accuracy, do require more manual effort from the golfer. In order to obtain a distance measurement, golfers must aim the device at the target, which can be time-consuming and challenging, especially when dealing with obscured or small targets. For golfers who prioritize ease of use and convenience, GPS rangefinders may be the better choice.
