New Tech Tip Guides by Petzl contain their usual level of great information and fantastic illustrations that we used to get in their Sport Catalogues. Each Tech Tip Guide covers a subject that usually gets skirted over by those of us that have been doing it a while and undervalued by those that are new. Things like good belaying practices, why you need to wear a helmet, planning trips etc.
