    yes, but the design was fairly old and i have not seen anything to replace them once they were discontinued.

    I was very interested in how computers track oxygen exposure, It is the Seiko Epson method that utilizes the 90 minute half life and has been used since 1992. Is this the same Seiko who built some of the earlier dive computers? Theory behind the half-life of CNS toxicity? My Dive Rite Duo from 2008 was said to run a variant of Buhlmann.

    I had the Trio, and the software included a 'Deep Stop' option (please no trolling about the pros and cons of that, please). It was more of 'Pyle Stop' if I remember well.

    I've owned a number of Seiko-made computers private labelled as Dive-Rite and Tusa. My understanding is that they got out of the business a while back because sop many of theirs were failing. I've had three of mine fail out of six. Another one was stolen but the last two still work fine (dove with one of them today)

    It's my understanding also that Seiko pulled out of the dive computer business a few years back. One other factor in this might be that over the last 10-15 years it has become increasingly possible for small market, independent developers to produce very sophisticated electronic devices. The development & manufacturing process has democratized significantly, and there is less reason to turn to a large company to manufacture for a niche market. And diving is a very niche market.

    Still, I will regret those computers (had a Dive Rite Nitek for 10 years, then a Trio, still working but showing some heath problem : beeping all the time, telling me I'm ascending too fast, even though I'm lying still on the bottom. I did love that computer : easy to use, even to switch between mix and the electronic compass was a treat !).

    They were a nice improvement, compared to my 1st computer : a Beuchat (Cochran inside) Maestro Pro, which conked out after 3 years, and less thant 60 dives... And Beuchat customer service was worse thant lousy : never got an answer from them...

    I was wondering, which computer was the last one Seiko designed for Dive Rite ? Does anybody know ?
