Gekko does me. Shows remaining deco and ceilings, works well on Nitrox, assuming you dial in your mix near to dive time, do it too early and it reverts to air (about 60 mins before dive time I think). Not too happy with the lack of back light though (poor eyesight and crapo viz dont help
)
But other than that I like it, I'd buy the same again if I lost mine.
Had 4 Suuntos now (son also dives) all are/were good - no bends suffered (yet), they are a bit conservative but that's ok in my book.
