The short circuit should be avoided for the battery of green laserpointer

The combination of access to information, to finalize the overall design of the laser pointer, including the specific structure of the laser pointer, the introduction of features. The shooting was the military, public security departments the necessary training courses, and sometimes military training for students also need to be shooting. Traditional shooting training not only need to occupy a large area of the shooting range to use on the range of genuine firearms shooting fixed or movement of a single target, but also a waste of bullets, and also need a dedicated staff of security, training costs are very high. In order to overcome the shortcomings of genuine firearms training laser simulation shooting training equipment, laser pointer is a key component in the laser simulation shooting equipment at design time to fully consider the accuracy of it quick and easy installation and instructions. The overheating of battery of  green laser pointer  should be noticed.
Moreover, the use of laser simulation shooting training equipment can solve the problem of real-time display of shooting range protection difficult, rainy weather is difficult to carry out live firing and shooting conditions. In addition, with laser technology, microcomputer technology, sensors and microelectronics technology of laser simulation shooting training equipment, the armed forces grass-roots companies, allowing commanders and soldiers, cadres at grass-roots and the culture more and more high quality soldiers in the day-to-day military training, frequent contact with a variety of high-tech electronic technology. Strengthening the army, people-oriented requirements of contemporary army building. Laser simulation shooting training device design and implementation of the modernization of national defense construction, military training and intelligence, to improve the overall quality of troops and defense spending savings are of great significance. And at the same time, the battery of  green laser pointer can not be burned.
Research at home and abroad with the advent of lasers, semiconductor laser, the laser simulation of firing technology is growing rapidly, especially the emergence of semiconductor lasers, electronic technology and the rapid development of micro-computer technology, the laser simulation shooting had a profound impact. Into the 1980s, small arms laser simulation shooting by the simple training of the ordinary laser beam simulation firings, develop a variety of different warring army weapons training simulation of the laser beam. Training system from the development of technical training to simulate tactical combat training. Guise of a variety of advanced light weapons simulation training system, an endless stream of products which typically have three categories. The battery of  green laser pointer can be torn off.
Ring laser gun shooting target, this training simulator appeared earlier, but also the most popular, mainly for the basic aim and shoot the technical training. It has a meter ring and spot trajectory measurement type (shooting analysis system) two. This simulated firing exercises commonly used laser components into the barrel (commonly known as plug-in type). Shooting when it is generated by the laser beam received by the circular target, and automatically reported to the orientation and the number of rings of the point of impact. This training in the United States and other Western countries and China have production. Finland Knopp Lyle flexor production of the ST-100 shooting training analysis system can measure and record the sights V Xi'an University of Technology Northern College of Information Engineering graduation project (thesis) to prospective and shooting the whole process. For same danger might be caused to  laser pointer  .
