Description
Challenger II - the next level of challenger series

The Ultimate Design
Sanwu aims for compact laser design and the challenger II is the most successful laser model we ever create. The laser runs by either one single 18650 li-ion battery(Battery life wise) or two 18350 lithium batteries(Maximum power wise)- you get 10 - 20% more power than the outputs listing here.

Best Size Ratio  
Challenger II has the best power and size ratio, it is capable to power a 4000mW 470nm blue laser diode with the size of a mini flashlight- in merely 140mm*24mm which feels comfortable 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.

Laser Function
Single mode 

On / off

Multi-operation mode
Low power > Half power > Strobe > Full power > SOS 

Half-press the tail switch to cycle between each operation mode, the laser driver memorizes and starts with the operation mode that being used for more than three seconds during the last operation.

Electronic safety lock(only accessible in multi operations)

To prevent unauthorized use, half-press the tail switch three times within the first three seconds after the laser is on, the laser will switch to strobe mode before entering the safety lock.

How to unlock?
Turn on the laser, wait one second and do five half-taps within three seconds, wait another 2 seconds and the laser should switch to strobe mode which indicates your laser has been unlocked.

Battery protections
Our lasers come with several battery protections to protect the laser and battery: over-discharge protection, over-charge protection and reverse polarity protection.

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.

Amazing!

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!
