Challenger II requires two li-ion rechargeable batteries to run instead of one. The higher battery capacity means longer operation and a solid duty cycle : 2.5 times longer than challenger series.

write review
The Challenger II is a professional handheld laser in every aspect. The build quality and machining on these units is simply breathtaking. These lasers are custom built per order with fine attention devoted to every detail. These handhelds are not the typical cheap lasers sold by other vendors. They are simply works of art. Furthermore, the representative I dealt with during my purchase was Francis, who is a very kind individual. He is very patient and answers any questions you may have quickly and efficiently. He is a great source to discuss the details for each build. I will only purchase lasers from Sanwu exclusively after seeing the quality handhelds produced by this company. You will be hard pressed to find any comparable products, period.
