> anyone have any experience with the Suunto Ion, or Suunto's in general? I assume that you mean the Suunto Eon, which is functionally identical to the Suunto Soulution except for the addition of air integration. The Solution is a good computer, I have extensive experience with it and IMHO it is the second best computer for decompression diving. Compared with the Uwatec computers (Aladin Pro, US Divers M2, etc) it requires about the same amount of decompression on the first dive, although the first stop is IMHO a bit too shallow. The computer tends to underestimate the ascent time; on the bottom it calls for similiar ascent times to the Uwatec computers, but unlike the Uwatec's, the computer takes significantly longer than it says to clear. It gives more bottom time on repative dives than the Uwatec, especially if the first dive was a decompression dive and the surface interval was an hour our less. It is still much more conservative than the Orca computers on repets. Overall I think with the exception of a somtimes too shallow first stop, it is a safe algorythm. I do take strong exception to air-integrated computers. In the last five years, of the four divers I have seen run out of air, three were diving air integrated computers. In one of those cases, it was due to an incorrect pressure guage reading on a Orca Delphi (1000PSI when he had 0). In the other two cases, I belive it was becuase digital numbers do not "sink in" the way a guage reading does. A glance at a guage at 300PSI, well down into the RED zone scares most divers, but a nice digital readout saying "318PSI" doesn't seem to shake people up. This was my experince when I was diving my Delphi (for the short time it lasted); I found myself pushing my air MUCH more. Jody Svendsen MiG Technologies
