The Geo Air has all the features you loved about the Geo 4.0, but now comes with the ability to connect to a transmitter, making the computer air integrated. Through the computer's programming, the Geo Air can read your general air consumption, and then estimate your remaining air time on a dive, based on the depth that you're at. This can be a handy feature for any diver, as different dives, depths, locations, and conditions impact the effort required for the dive, making for varying air consumption demands.The Geo Air features a large, legible display, making for easy use underwater and on the surface. This computer is equipped with Oceanic's proven and well-loved Dual Algorithm, which delivers greater bottom time whilst keeping divers safe. Bluetooth connectivity to all smartphones allows divers to keep track of their underwater exploration through the DiverLog+ App. Equipped with the ability to be used as a watch, with air, nitrox (2 mixes), for freediving, or in gauge mode, this watch offers versatility for different diving demands. A diver of any level, whether just starting out, or well experienced can use this dive computer to progress their skills, review data, and dive anywhere in style.
