Some is plain daft. For example they claim that theirs is the ONLY way to dive. Well for a start if they tried "cave" diving in England they'ed come pretty unstuck. "Cavern" diving their config may be good for, but for a 6 hour carry to dive in a 22 cm high passage it would be a joke. Long hose is a no-no for UK caves cos you dive solo (you cant physically fit a buddy in most sumps), also where are their helmets (oh they dont actually cave do they)
Get the book, read, learn and come to your own conclusions based on your circumstances. For example I use a few too many D rings and have 2 contents guages (one digital with beepers and one good old fashioned oil filled. Dont trust electrics but the display is much better than a standard SPG). I carry a dayglo hood, 2 reels, a red and yellow SMB, net cutters, a extending flag and 3 knifes (The surface is rough in the UK and I want the boat to find me). Having had to use a knife in earnest quite a few times, I laugh at the little thing GI carries. For big heavy trawler nets you need a good 10" job. I also carry and use a buddy line, we dont have US cave VIS in the UK waters. I also carry a small perspex tube filled with distilled water so I can read my guages in ZERO viz
DIR have some very very good ideas (although most were borrowed from others) but they are not the difinative method
