Powerful Green Laser Pointer for Scuba Diving (100mW / 1000mW)

I chose the 1000mW version. The green laser is bright, but the beam is a bit thick.

I often use this laser to point out corals or fish. It can work continuously underwater.

The penetration of this laser is really strong. Its green light is very clear underwater.

I need to use this laser when diving. It works well at a depth of 100 meters underwater.
