When playing golf, it is important to know the distance at the first time, which determines the quality of the score. In practice, players often judge the distance from the ball to the flagstick by visual inspection of themselves or their caddies, so as to decide which iron in the bag to choose and the power of the swing. In addition to the player's own level, the selection of professional equipment is also very important. The most direct equipment is the laser rangefinder (monocular type rangefinder).
Misunderstandings that are easy to appear when purchasing a laser rangefinder:
1. Blind pursuit of high indicators
Any product has its own technical indicators, and high indicators of course represent relatively high performance. The most important technical indicators of a
golf rangefinder are its measurement range and accuracy. With the continuous technological breakthroughs in the accuracy and range of laser rangefinders in recent years, many players want to keep their equipment accurate at all times, so they desperately pursue products with high precision and high measurement range when purchasing. . In fact, this purchase is a misunderstanding. It is impossible for the rangefinder to fully meet the conditions of the parameters, and there are many interference factors, such as harsh environment, complex terrain and the actual measurement target. When purchasing, if the user wants to measure the effect of 600 meters, do not choose a rangefinder with a parameter of 600, because this may not achieve the data you want to measure.
2. Blindly pursuing high prices
Now the price of laser rangefinders is very unstable in the market, so many users think that a product with a high price is good when purchasing, regardless of its performance and its applicability. Often they don't start complaining until they use it, and then have to spend money on other styles. So everyone remembers when buying a rangefinder: the price is not the point, the point is the product itself. See the product function clearly and don’t blindly pursue the low price, pay attention to the error of the product’s functional parameters, the function is not as good as the fine, choose according to your own usage habits and needs, and seek professional guidance if necessary.
3. Ignoring "safe" and "unsafe"
As the name suggests, laser rangefinders work with lasers as the main working substance. At present, the working substances of the handheld laser rangefinders on the market mainly include the following:
Semiconductor lasers with working wavelengths of 905 nm and 1540 nm, and YAG lasers with working wavelengths of 1064 nm.
The wavelength of 1064 nanometers is harmful to human skin and eyes, especially the eyes. Once exposed to the 1064 nanometer wavelength laser, it may cause permanent damage. So the manufacture of hand-held laser rangefinders completely outlawed the 1064 nm laser.
By eliminating these misunderstandings, players can quickly choose a rangefinder that suits them and achieve good results.
