Challenger II - World first copper made powerful handheld lasers
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.
I recently purchased two Challenger II lasers as astronomy pointers and I must say that the build quality is superb and the host electronics are excellent. Being able to custom order a laser is a big advantage for me, especially with the large selection of diodes, and collimating lens options, including a beam extender (necessary for higher power diodes). I know of no other vendor that offers such a service and delivers such a high quality product. I m very satisfied with my purchase, and I will be back! Thanks!
