It is a bit confusing, because "lasertag" is usually really LED TAG with optics. So the sensors you linked are for a broader beam LED tag system. It is going to be a lot harder with a real laser, if that is what koosa is intending, since the beam is so small.

I have never tried it, but I have heard that you can sense light with standard LED's. You might be able to build your own target array with them. Here is a simple single LED on a multimeter. http://mvh.sr.unh.edu/mvhinvestigati...d_emission.htm
