We examine the characteristics of the magnetic field in Saturn's magnetotail lobes and current sheet during the Cassini spacecraft's exploration of the magnetotail from day 18 to day 291 of 2006. During this period Cassini reached maximum downtail distances of similar to 68 R-S, with orbits at the beginning of the survey interval concentrating on the equatorial regions, while later orbits moved to somewhat higher latitudes. We find that the field strength in the lobes falls off as B-lobe (nT) = (251 +/- 22) x (r (R-S))(-1.20 +/- 0.03). We show that the lobes and current sheet have distinctive magnetic pressure distributions, and we examine the transition of the field from the central current sheet out into the northern and southern lobes.
