Challenger II - the next level of challenger series

Everything bigger
Starting off with bigger copper host and heatsink, challenger II comes with engraved surface as default and the extended battery space can take a single 18650 li-ion battery(Battery life wise) or two 18350 lithium batteries(Maximum power wise).

The higher battery capacity and advanced heat sinking means it can go with stronger laser diodes - up to 4000mw with a 470nm diode.

Ideal sized laser 
Challenger II has the best power and size ratio, it is a extremely powerful laser yet comes with a mini flashlight sized body, the solid 24x140mm copper housing feels amazing to operable with one hand.

Seamless experience
As one of the leading handheld laser manufacturer, we always ensure top notch quality of our handheld lasers. The challenger II is focus adjustable and when you tighten all the moveable parts of the laser, you won't notice any signs of conjunction as the laser is made in one piece.

405nm 1600mw
Flawless craftsmanship, beautifully made and arrive within two weeks of placing the order. If you're looking for quality then look no further, the Challenger II like all other Sanwu laser products is brilliantly put together. The 405nm 1600mw laser is incredibly powerful too, so do not be fooled by its size.
Rob White
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.
Superb Craftsmanship!
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!
