I am looking for a page with information on the P50 A. When I searched for it I could only find this page. Please direct me to a page where I can find the information about the P50 A. It's just as easy to have this problem with counterfeiters in the USA, it's not just in foreign countries where we have these problems. Thanks Petzl for taking the responsibility to inform those who may be in harms way because of the counterfeiters.
