Just to clarify my earlier remarks, nothing wrong doing no-stop dives on VR3, I've done it myself. On my VR3 when it had v2 software installed, there wasn't a no-stop option on the menu, it just gave the no stop on the dive (-ve number). The no-stop menu appeared on a v3 upgrade when I had a screen replaced, i always felt it wasn't necessary. Bit like the altitude screen
