A 1W blue laser could easily cover as far as 450 miles and can be useful in presentations. The beam is able to be directed at many different directions, and even towards moving vehicles. However, a powerful laser may radiate its beam so wide that it's impossible to be seen from vehicles. In such situations it is possible for a more powerful laser to be used.<br><br>The laser power of a pointer varies. A 200mW green laser can be seen from over a mile away.
