Don't bother with a CPS Radar coarse I found this book far more informative and easy to follow. Don't let that Radar go to waste. We used ours at night, while anchoring and dodging weather, just in the PNW $10 The Weekend Navigator, great book. $10 Fast Track Sailing. Good for newbies, crew and guests. $5 The Wind came all Way. Excellent weather book for the Salish sea $5 How to catch bottom fish, new.
