Hi! The issue I'm having is making me quite nervous, so I hope you can help. I have two Vyper computers (both purchased used). After a three dive day in July, I downloaded my dives and saw that the download said I went into deco. My computer didn't indicate that in real time during the dive. I deleted and redownloaded the dive, and the NDL times through the profile changed for the same dive and now no deco was indicated. Being worried about this, I wore a computer on each wrist on a recent three dive day and compared them frequently on the third dive. They didn't agree with each other (e.g. one would have a 5 min NDL when the other had 12 min), but neither one showed an ascent time or a ceiling at any point (I was checking them every minute or so). When I downloaded them, both show ascent times and ceilings for a large part of the dive! I have downloaded both computers into DM3 and DM5, and the two versions of DM disagree with each other for the same dive. I'm getting to the point where I don't trust either computer and am tempted to replace them with another brand. Is there any way for me to know what to trust? Thanks! -Lisa
P.S. I just deleted and redownloaded the recent third dive in DM3, and now one computer shows what I saw during the dive (no deco), whereas on the previous download it showed ascent time and a 10 minute ceiling. The other computer still says I was in deco for 20 minutes... I wear both computers on all dives
