I have read all of Clive’s Excal/Sovereign/CTX/Pulse machine/general beach detecting books, they have paid for themselves over and over. I enjoy his writing style, as you can read quickly for an overview, then later read slowly to digest the fine points. He frequently talks about site specific problems, then explains how to work thru to a solution. The amount of experience that he shares is amazing. I recommend them without hesitation.
