Warning for the Dive Rite Nitek Duo

[LKunze]

If you are looking for something similar in features and price range that has the bugs worked out try the Suunto Vyper.  You can dive it on deco dives but if doing so it's best to put it in Gauge mode and dive your plan from your slate or wetnotes rather than have the computer do your deco as it likes to lump all the deco into the 10 foot stop at the end.
