One of the biggest plusses of detailed Ministry regulations has got to be that by not keeping up with technology, the old standby's never disappear. Even with all the mapping software, computers and eACR's on the rigs, the big book o' government rules still says they need a mapbook. So the mapbook sits there same as always with the old paper ACR's. Same goes for the number nine stretcher, canvas pole stretcher and a few others. You never know why you need it, until you need it.
