This project is a simple and practical digital rangefinder, a precision optical instrument used to measure the distance between you and the national flag. It adopts a ruby coated optical lens with ultraviolet protection function, with a magnification of 7x, 62 feet, and a field of view of 1000 yards. It supports two operating modes, namely green mode and normal mode. In addition, it also comes with a suitcase to protect the sight. It features a pocket design, is easy to use, and is an excellent 7X digital rangefinder to choose from. features -Color: As shown in the picture. -Material: Durable hard plastic. -And 7X digital rangefinder oscilloscope. -A precision optical instrument used to measure the distance between you and the national flag. -Magnify 7 times, 462 feet, 1000 yard field of view. -Optical lenses coated with ruby, with UV protection function. -Two operating modes: green mode and normal mode: 1. The green mode is designed specifically for golfers, allowing you to easily measure the distance from where you stand to the cup. 2. The universal mode can be used for other situations - it can calculate the distance between you and the desired object. -Powered by 2 * 3V batteries (included). -Bring a handbag to protect the telescope. -Pocket size, lightweight, easy to carry.
