Durable and Waterproof Yellow-Green Laser Pointer 555 nm 50mW

This 555 nm laser pointer adopts sturdy housing, internal protection, and humanized design. It is waterproof and durable, so you can use it in harsh environments. The yellow-green laser is stable, and you can see the laser beam in the daytime. Due to material and size limitations, the highest power we can achieve is 50mW. Many excellent features are available: PCB protection, circuit optimization, silicone switch, over-temperature protection, etc.
