Hey ya, I`ve been diving with an Oceanic Atom 2.0 now for about one year. I love the simplicity, and the features. The wireless transmission is solid and hasn`t gone weird on me yet. I really like the software Oceanic bundles with their products, it`s very intuitive. I think the VT3 probably is easier to read underwater due to the larger display, but this Atom is great when traveling. No complaints. Medium learning curve on navigating the menu, but reliable. Good luck, Kevin
