The ROV Manual by Bob Christ and Bob Wernli is a great reference book for operators, pilots and owners. A good manual that can be used as a textbook or simply as a reference has been needed for a long time. With chapters on subjects ranging from the history of ROVs, to practical, hands-on tips for specific types of field operations it is a wealth of information for the newcomer and seasoned pilot alike. I highly recommend it. (In the interest of full disclosure, I contributed the section on lighting in chapter 3 but don't let that dissuade you. This is an excellent book).
