Such an easy read, all the tips are nice, short and easy to get your head around. Purchasing this book you are being rewarded with the tricks and tips that these guys have acquired over years and they really go the distance. A must read for anyone in the sport, and this should almost be a prerequisite for anyone who wants to be a good dive buddy. A few tips that I made a conscious effort of doing and they have paid off big time. Also check out Shrek and Turbo's podcast noobspearo dot com (wont let me post the url) for a good laugh and even more tips then you could shake a stick at!
