Had one myself (EON Core), dive buddy had a Suunto too. Both locked out mid-dive, not even violating deco stops. So yeah, I'm done with Suunto computers. Their compasses are great though.
Absolutely! I have my trusty SK7 with me on every dive. For the type of diving that I do, I use it on just about every dive.
But after having multiple buddies have constant lock-outs, I'll never own a Suunto computer. I want a computer that is a tool under my control, not one that thinks it has to babysit me. Dive computer-lock-outs are probably the dumbest idea ever. They end up fostering exactly what they are supposedly trying to prevent which is unsafe diving. They lead divers to do stupid things like pop the battery to reset the thing.
