Hi im looking to buy another computer after losing my Gekko! :doh: I've been looking at the stinger as I know it's an excellent computer, but then i see Suunto have brought out the D4, which looks just as good for what i want, and a little bit cheaper! I also looked at the Aeris Manta, which i've never seen anyone use. It sounds like it has all the features that I would require but not sure about the reliability, ease of use etc. Anyone used the Manta? Thanks...
