Remind me it was my first He computer and at the time, in the last century if I remember correctly, it was THE computer
Any idea about Dive Rite computers' time line? Is the list below correct?
1.Nitek
2.Nitek 3
3.Nitek He
4.Nitek Duo
5.Nitek Trio
4.Nitek X
5.Nitek Q
I have a Nitek Duo that I bought in 2008 and a Nitek Q that I bought in 2016. The Duo was inexpensive as the Trio was being introduced.
The Nitek Duo is said to run a Buhlmann variant. I've always been a bit confused by the 9 compartment model. So is this the Seiko algorithm, written by Randy Bohrer?

At the time I bought the Duo, I was diving an Oceanic Pro Plus 2 primary (DSAT), backed up with a Cochran EMC-14. I bought the Duo because the Cochran was so unwieldy to use. Unfortunately, the Duo was so conservative that it was not useful to me as a backup. I had no information on the algorithm when I bought it. Turns out it is a bit more conservative than PZ+. I still have the Duo and it still works, but it has not seen any use for many years, not even as a loaner
.
The Duo was quite popular at the time, introduced around 2004, and there were many clones, branded by other companies, Zeagle N2ition, Tusa IQ-700, Cressi Archimedes, Apex Quantum, perhaps others.
Of course, the Nitek Q runs Buhlmann ZH-L16C with GF. I used it for 3 years while learning Buhlmann before I switched to a Teric. The Q was obtained for only $400 from DGX, maybe a year before it was discontinued. It still gets a fair amount of use as a loaner.
See my previous post regarding the algorithm developed for tracking oxygen exposure
Seiko inside your divecomputer? I think this might be an ongoing contribution from the Seiko-Dive Rite collaboration.
Edit: Though I have searched this topic many times, somehow, I missed this very interesting post from
@tbone1004 Need help choosing a new computer, read this It doesn't necessarily address the short NDLs of the Duo, but it does contain a lot of very interesting background regarding the Seiko algorithm
was already made by Seiko. So were the Nitek Titanium, Nitek 3 and Nitek He. Those predates the Duo and Trio. Then there was the Nitek X, which was a failure, and the Nitek Q. I've absolutely no idea who designed those 2. I dive on a regular basis with the Q as a backup to my Shearwater Petrel, nothing to compalin about.
