The small volume of receivers in cell phone jammer is space-saving

 The small volume of receivers in  cell phone jammer is space-saving.
When you are interact with the audience, the target content will automatically appear on the screen when you use a  cell phone jammer. Weapon Sight wire differentiation, not for any reason, targeting crosshairs made of glass. Not required that the glass has been able to make a differentiation in the form on this home and abroad are Q: What is a continuous zoom? domestic Qiangmiao continuous zoom features? A: continuous zoom is the meaning of calibration such as four times the case, then, if you want to aim at distant targets or focus on the target observation, then need to select the magnification zoom magnification or magnification change for small magnification of the zoom process is called by the small rate changes.
 but only into the light hole a certain distance to see the clearest full screen imaging. This distance is the exit pupil distance. Any optical observation equipment has exit pupil distance, the difference is that the telescope of Galileo telescope system exit pupil from the general naked eye and the eyepiece can be affixed, and the use of optical laser pointer of the Kepler telescope system in order to prevent weapons recoil laser pointer knocked down a user's naked eye, so the exit pupil distance to leave the eyepiece a certain distance. 
The first generation is a single portable  cell phone jammer. only the naked eye to enter into the light hole to see like, and only enter this light hole a certain distance in order to see the most clear full-screen imaging. this distance is the exit pupil distance. any optical observation equipment has exit pupil distance, the difference is the telescope of Galileo telescope system His exit pupil from the general naked eye and the eyepiece can be affixed, and the use of optical laser pointer of the Kepler telescope system is small in order to prevent the weapons recoil laser pointer bruises user's naked eye, so the exit pupil distance left eyepiece a certain distance.
The laser was the main part of the first generation portable  cell phone jammer. the implementation of targeting observed in the most clear imaging from the best angle in the exit pupil distance. "11. How the adjustment of the optical laser pointer according to the text on the adjustment knob adjustment? A: The high quality Weapon Sight with anti-vibration control knob, each regulating a cell will have a click a sound on each adjustment plate marked in English. For example, marked for 1CLICK O 1/4 "YD he meant 1.00 per regulate a cell (a clicking sound), 100 yards away, the amount of movement of 1/4 inches.
