How Golf Rangefinder works
Calculating distances during a golf game is not an easy feat especially to amateur players. Rangefinders make it easier by estimating distances within the golf course. These devices serve the same purpose but have disparities in terms of accuracy and functions. Currently, there are three main types of rangefinders; Laser, optical and GPS.
Let’s delve on each one of them and find out how they work, also you can follow the link to find the best golf rangefinder.
How a Laser Golf Rangefinder Works
Laser golf rangefinder uses laser beam technology to verify distances. Basically, a user points a rangefinder to the target. The target then reflects the beam back to the device. For proper functioning, lasers use a line-of-sight method. So, if there is any terrain or trees blocking the view, it may give inaccurate measurements. There are new sophisticated lasers made to counter that challenge. These advanced devices have an inbuilt inclinometer that calculates distance down the slopes. Another downside of a laser is that it may focus on various background objects resulting in inaccuracy.
To solve that, there are new brands coming up with a pin seeker feature. This element points out and disregards unnecessary objects in the background.
How a GPS Golf Rangefinder Works
GPS rangefinders use the satellites to confirm distances when playing golf. This device is one of the most accurate forms of rangefinder. Most GPS rangers use Google maps to get precise location and measurement. The process starts when GPS receives signals from the satellites. After, the device responds and calculates the distance to the specific target requested. The market now has advanced GPS rangefinders with satellite maps that give a golf course layout.
To operate a GPS rangefinder, you need to load the map for precise calculations first. Some gadgets come with preloaded courses. In rare cases, some GPS rangefinders may demand a membership fee to access the maps. A reliable GPS gadget should give the view of the front, center and back of a green. There are also some GPS rangefinders that warn the user of hazardous areas or risky spots. Almost all GPS devices come with adjustable touch screens where one can alter the golf hole location.
How an Optical Golf Rangefinder Works
Optical rangefinders are monocular devices with in-built scales for measuring. They use a parallax perception which uses two lenses at both sides of the device. A focus knob overlays the images from the lenses and converts the readings to distance. To operate an optical, the precision of your image depends on how you focus on the target. This gadget operates without batteries, course downloads or subscriptions. While they offer a cost-effective option, the results are not always accurate.
The Final Word
When choosing the right rangefinder, you need to consider the price and purpose. The price of optical rangefinders may attract most players, but the downside is that it is not as accurate as the others. Laser rangefinders offer reliability especially in hilly terrains with the in-built inclinometer. If your main intention is to get the optimal accuracy and consistency, a GPS rangefinder is a sure bet
