The main difference between true and false Dr. Energy is that if the product is imported from the United States, the watermark number of the relevant product can be found on the mirror of the telescope.
2. Impression of Bosch brand logo
Generally speaking, the cost of fake goods is low, so the materials used to make telescopes will not be professional materials. When you get a doctor's telescope, first look at its brand logo. Generally speaking, the authentic Bosch brand logo“Bushnell "is hollowed out and embossed on a telescope. And fakes are often simply printed on the environment, and some can even be gently peeled off by hand.
3. Working in the outer layer of the telescope
The shell of the telescope is very rough. Because the merchants cut it themselves, some even have gaps. The surface seam is very uneven.
4. Eyepiece knob details work
There is a major difference in the appearance of genuine and fake doctor telescopes: if the products are imported from the United States, the model and batch number of the products are usually printed. Indicate the origin and export place of the product. Can a fake doctor print this identification number? The eyepiece knob is generally adjustable, and the other side is fixed and cannot be adjusted. Mainly to adjust the eye spacing. If you find that the eyepieces on both sides can be adjusted, it means that the eyepieces on one side are not fastened properly. Some even fell off when they turned the corner.
5. Significant effect difference during observation.
Of course, when observing, it is best to distinguish the true and false degree of true and false products. When the authentic doctor telescope is observed, the observation field is wide and bright. The clarity of the measured object is clear and bright after adjustment. Even the edge of the field of vision is bright and thorough. Imitating doctors can't achieve this effect. The clarity and brightness of the measured object are the main differences between them. I feel that the imitation is not clear enough and the brightness is not enough. The edge of the objective lens is blurred and the field of view is narrow.
6. The cost gap is very large
The core prism system of genuine doctor telescope and the prism itself are imported from the United States, and all of them use A-grade optical glass, while domestic fakes use B-grade or C-grade glass. Note: A-grade optical glass is mainly used for high-grade lenses, while B-grade optical glass is generally supplied to the domestic ordinary market, and C-grade optical glass is also called inferior, so it is generally not allowed to be used for export products. All the products we provide now are A-class high-quality optical glass. The manufacturing gap of this glass alone has reached nearly 6 times. The same telescope, the genuine one will contain 6- 10 different types of prisms, and the fake one may only have 2-3. The gap in cost price, selling price and quality grade brought by this aspect is obvious.
A considerable part of Doctor's products are made in China. Only a few high-end products are produced abroad. But domestic production is also OEM assembly. Core components are imported from abroad. After all, the research and development ability of domestic high-end prism system is still limited, but the imitation ability of skin material is strong, so it is difficult to distinguish genuine products from imitations in appearance. It is necessary to understate the details and distinguish them after actual observation. After all, there is a big difference between genuine goods and fake goods in terms of the quality of the products themselves. In order to pursue the best after-sales service and product quality, we sincerely hope that you can find a regular doctor dealer to buy. So as not to cause unnecessary losses.
