Four misunderstandings in buying laser rangefinder
● Blind pursuit of high indicators
Any product has its own technical indicators, and high indicators certainly represent relatively high performance. The most important technical index of ranging telescope is its measuring range and accuracy. In recent years, the improvement of accuracy and ranging range has been extremely rapid. At present, many products have broken through the 10 million mark. Looking at every few months, the accuracy and ranging range of new products of laser rangefinder increase as well. Many people in the surveying and mapping industry feel that in order to keep their products accurate at all times, they must have a certain amount of advance, so they desperately pursue high accuracy and high measuring range when purchasing.
In fact, this is a complete misunderstanding. In addition to ranging and accuracy, it is impossible for the ranging telescope to meet the requirements of the parameters completely, such as in harsh environment, actual measurement targets, and complex targets, etc., to judge whether the selected instruments meet their own engineering requirements. If you buy a 600-meter parameter and the user wants a 600-meter one, don't choose a 600-meter parameter, which may lead you to fail to reach the data you want to measure in engineering.
● Think that "domestic products" are not as good as "foreign goods"
This misunderstanding exists not only in laser rangefinders, but also in other products, indeed. On the * * and professional-grade products, China's ranging mistake is slightly inferior to that of foreign products, and it can't even reach the high performance and high index of some "foreign goods". But relatively speaking, there are some low-end products in China, which are very mature. Compared with "foreign goods", our "domestic products" are not inferior, and they also have certain advantages in price. Therefore, if you are a user in the surveying and mapping industry and want to buy a "low-end" product, you may wish to pay attention to our domestic products.
● Laser receiver
The laser receiver of laser rangefinder is an important technical index, so many users attach great importance to it when purchasing. Different machines have different echoes when aiming at the same target, and the echoes of laser receiver are different when ranging distance and ranging accuracy are different in rainy and foggy weather. When users buy, they must go to the physical store face to face to experience the effect of the laser receiver. Now many dealers have set up physical stores, which can ensure the accuracy of the measurement and the easy measurement of complex targets.
● Blind pursuit of high prices.
The price of laser rangefinder is very chaotic in the market, and many products have this phenomenon. Therefore, many users agree that high-priced products are good when purchasing, and blindly pursue high prices, regardless of performance and whether they are suitable for their own use. On the contrary, when you buy it for real use, it will be miserable. You have to spend money again to buy another one. Price is now extremely important in the minds of consumers. Therefore, when choosing a laser rangefinder, we should pay attention to the ranging range, ranging accuracy, measured amount, function, lens, multiple, laser, bad conditions and so on. Price is not the key, the key product. Domestic brands and foreign brands depend on their own use. If you are a person who is used in surveying and mapping industry, don't take a look at the product functions of laser rangefinder, and choose a laser rangefinder suitable for engineering use.
