Alex

I've only been able to dive with it twice. At first glance, it looks quite large, even though I'm used to the Mares Puck Pro. It has a large color screen with countless parameters and data. If you're not going to dive professionally, it's too expensive. But if you are, it could be a great work tool.

It is a dive computer with a very good interface and features, but it is sold with properties and features that it does not have today. The Genius model does not connect to DiversDiary (so you cannot transmit the logbook to your computer or smartphone, or upload maps).

Best diving computer to date
