A warning to anyone thinking about buying this book. The writing and grammar is very poor, frequently to the point that I couldn't work out what was meant. I have a fair amount of experience in tracking, a beginner, unfamiliar with tracking terms and methods, wouldn't stand a chance. There are factual errors. There is no logical structure to the book, which randomly jumps from one subject to another. The subject matter is rather bizarre, including lots of detailed police procedures, military procedures, search and rescue procedures, medical human anatomy terms etc, but very, very little in the way of actual visual tracking skills. I was looking forward to reading the book and even when it was clear that the presentation was poor, I ploughed on, hoping to extract a few nuggets of tracking information. However, there were no great nuggets, only a few garbled bits of tracking information.
