Ocean is a great hardware, that could easily compete with Teric and MK3. However, it is totally limited by the firmware. I hope it changes in the future.
If you really need trimix, by now, ocean is not for you.
Until trimix, Ocean needs a lot of updates on the screen infos, screen organization, screen customization, dive planner, compass, GF99, SurfGF…
