For some reason i seem to know what almost every computer on the market looks like when its bent.
Suuntos do not show SOS (or five past five) unless they are one of the older models such as a favour or solution. If you dive a modern suunto while it is still bent it will do gauge mode but thats it.
If you dive one with a very very low battery it will not tell you anything at all (time depth) and bleep every five seconds (dont ask how i know this one).
We did have a gekko go all weird, did a microsoft reboot on it (battery out and back in) and then it seemed ok. Couple of weeks later i wore it to shift a shotline and it still thought it was back on the boat.
Ho hum.
