If you want to get a taste of my latest book Digital Masters: Adventure Photography, my publisher has put together a sample PDF with several double-truck spreads from the book including those you see in this blog post. The spreads included are the introduction, a spread from Chapter 1 on photography gear, one from Chapter 4 on artificial lighting, a spread from the surfing section in Chapter 6 and a spread from Chapter 9 which talks about what it takes to make it as a pro adventure photographer.
Included is a composite of my main gear kit (below), which I shot over the course of two days and composited together for the book. Of course not all of this goes out on a shoot with me everytime, but this gives you an idea of the typical gear used by pro adventure photographers these days.
