1. Application
The 7×32 straight telescope is a handheld binocular telescope with a roof prism optical structure design and a rough measurement function. It is mainly used to observe the environment, scenery and targets.

2. Features
Small size and light weight: Through reasonable structural design, the product weight is less than 660g.
Good sealing: The mirror body is filled with dry nitrogen, which can maintain good dryness and sealing in various environments to ensure comfortable observation requirements.
Good anti-vibration performance: The product can maintain a good use state in the event of sudden drop and vibration.
Strong material：Double separated lens, aluminum alloy integrated lens body

3. Main components and functions
The telescope consists of two major parts: the optical system and the structural system. Among them, the optical system mainly realizes the imaging function of the telescope; the structural system mainly carries the components of the optical system and assembles them into a complete product.

4. Structural system
The telescope consists of left/right eyepiece group, left/right mirror body, left/right objective lens group, etc. The telescope structural system realizes the observation of the target through steps such as eye distance setting and diopter adjustment.

5. Vision adjustment
When using a telescope to observe a target, you should hold the telescope facing the target, close your left eye, and turn the right eyepiece group until the target is clear; then open your left eye, close your right eye, and turn the left eyepiece group to adjust the target to be clear. Use the above method to continuously adjust the left and right eyepiece groups until both eyes can see the target clearly.

6. Use of the reticle
a. Use of Reticule on Measuring Azimuth Angle
b. Use of Reticule on Measuring vertical view angle
c. Use of Reticule on Distance Measuring
d. Use of Reticule on Measuring Height and Width of Targete
e.Quick Fixed Elevation Distance Measuring

7. Use with a gas mask or glasses
The rubber eyecup of the telescope can be folded down, which is convenient for people wearing glasses and gas masks to observe directly.
