Today, with the continuous progress of education technology, a good auxiliary tool can greatly improve the quality of teaching and students' interest in learning. The 5-in -1 laser pointer is such a "teaching assistant". It skillfully combines five powerful functions. It not only has the traditional laser pointer function, but also supports infrared remote control page turning, sound amplification, timing reminder and other functions. Its exquisite and compact design is both beautiful and practical, and is an indispensable helper for every educator and speaker.

Because of its strong penetrating power and clear spot, green laser stands out among many colors and becomes the preferred light source type for 5-in -1 laser pointer. Whether in a bright classroom or a dim lecture hall, it can accurately mark key knowledge points and guide the audience to focus. In addition, this laser pointer uses high-efficiency energy-saving technology, even if it is used for a long time, it hardly consumes much power, ensuring a long service life.

With the built-in infrared sensor, the 5-in -1 laser pointer can easily remotely control the page turning operation of PPT or other documents.
