Making laser tag with real lasers

They used an advanced version of MILES when I was in AIT. Worked great and doesn't blind people. You could game it if you didn't mind doing pushups until 12 o'clock the following summer.

Thanks so much!

Hi, had a doubt that would you consider the Ky-008 laser module dangerous? It is around 5mW Laser.

Also Laser has how much frequency? (Means less than Visible spectrum or more than Visible spectrum)?

I saw those. The problem is that the laser has to hit the receiver dead-on, and it's very small. Which is why I'm using an IR laser with a bunch of IR receivers.
