From the basic principles through to more in-depth expertise, Essential Boat Radar is your no-nonsense introduction to radar. It guides you into the subject by providing sufficient information to understand what's going on, proceeding directly with basic radar use.Bill Johnson clearly explains what radar is, outlining what is does and doesn't do. He describes how to make simple adjustments to get a decent picture, and explores how to use the basic radar. This is followed by greater information on the various confusions and anomalies that the picture can present, progressing to the more complex functionality of a modern digital (raster) set. Finally, you learn the key elements to consider when choosing a radar system for your boat, and also how to install it.Essential Boat Radar includes: full explanation of what radar does, and how it does it how to use radar for collision avoidance, with reference to the relevant COLREGS how to use radar for navigation and pilotage practical exercises for using radar detail on related subjects, such as: AIS, radar reflectors guidance on choosing and installing radar systems
