First dive on my new redbare yesterday - superb it was sooo much easier to dive than my old sentinel. The latest version of the software nice, logical and quick to respond. Personally I'm not sure I like the apeks mouthpiece, doesn't feel as comfortable in the mouth as the old Poseidon one (even though I use apeks on oc) so Martin kindly gave me one to try. If you like ferreting in holes then this unit seems slimmer (at least I got into places in vobby's underwater toys that I couldn't with the sentinel). WOB ace, buoyancy control easier (could be I'm a better diver now, difficult to compare but giving how little ccr I've done in the last four years I'd say the unit was flattering me). HUD easier to see in bright light (smaller more intense led), and the alarm sequences are more sensible. Easier to break down to clean and allow to dry, charging via some proper plugs rather than Fischer connection that was always a bit flaky.
I'm not at all disappointed with this purchase and I honestly don't believe that anyone currently waiting for theirs won't be either
