Puntatore laser rosso impermeabile QK-DS6 1000mw 638nm 5 metri sott'acqua

A very sensitive laser pointer, the red beam is also very clear, I like it very much.

its a great purchase. Very clear during the day!Works well. Green spot can be seen on buildings in daylight. The beam can be dimly seen in the air in daylight if looking straight down the beam (away from the source of course!). Beam quite visible at night.
