| VR3 BUH or VPM
Hey Guys,
I recently returned from a dive trip where I took both my VR3 computers and dived them both. They are both running Ver 2007, one has BUH and the other has been upgraded to VPM.
My thinking was that I would dive the most conservative of the 2 which I did but with interesting results.
All the dives were around 75m with the longest bottom time being 50mins. As expected the VPM computer started the stops deeper than the BUH and was constant throughout all the dives. by the time I had cleared the stop the BUH comp had cleared also and was indicating a stop at the next higher level.
This was the case right the way up to the 9m stop where the BUH computer sometimes still had a little time left to run at the stop also but when I got to the final 6m stop and cleared the VPM computer the BUH had, on this particular dive, another 60mins to run.
It would appear the BUH computer had been penalising me for the time I was stopped at the deeper stops whilst following the VPM.
I follow the thinking behind the VPM modelling as compared to the BUH but is the VPM really any better in the real world or is it just as hit and miss as BUH?
Any thoughts on the subject or experiences, bad experiences on one over the other?
Thanks,
Lance |
