A quick follow-up to my earlier postings: Now that the computer has been exchanged for the second time, the compass finally seems to work without problems. I have used it for four dives over the last ten days, and all has been well now. It does lose its connection to the transmitter once in a while, but always recovers it quickly. Visibility of the display works for me in essentially all circumstances. One thing I hope they will change is that it displays O2% where it now just says generically "gas 1" in normal dive mode. One more chance to catch a mistake in the gas setting. Also, I would hope that they will have a dedicated more to support sidemount, displaying the pressure of two tanks simultaneously. But otherwise, I'm happy with it.
