Su Guang DL300 handheld laser rangefinder

In a right triangle, the square of the hypotenuse is equal to the side length of two right-angle square of the length of Collage and this phenomenon is called ---- Pythagorean theorem, otherwise known as the Pythagorean theorem, commercial high-theorem, donkey bridge theorem, Egypt Egypt called triangle, etc. In short, the Pythagorean theorem is the geometry of the pearl. It is in the hand-held laser rangefinder famous theorem based on the use of advanced non-cooperative target laser ranging techniques to measure the target for easy measurement of length, area and volume of the desired purpose. This product is compact and lightweight, using simple and intuitive menu interface, it will be used to get started, and user-friendly set up multiple units of measure for users to choose. Features: ■ user-friendly design with user-friendly design, built-in bubble level, you can be more flexible, accurate and efficient measurement, and is particularly suitable for small spaces. Everything is under control; ■ indirect measurement to measure the height very difficult? Now, you can use indirect height and length measurement function (Pythagorean theorem), with only one button can be easy to get; ■ quick and simple laser measurement, single control, the button will be easy; ■ dynamic measurements using dynamic (continued) tracking and measuring capabilities to locate the relative distance and position from the reference point, saving time, effort. ■ space operation built two space measurement procedures, calculate area and volume; Standard configuration: 1 portable pocket 2. Host 3. collision silicone sleeve 4. Operation Manual 5. Battery 6. 7. The side strap drop resistance strap parameters.
