The Geo 2.0 includes Dual Algorithm, Deep Stop option and a redesigned user interface with "Step Back" – which allows forward and backward navigation through menus and settings. Additionally, a second Nitrox mix (both programmable to 100%) is available, as well as Firmware Auto-Update which allows the user to download and install operational improvements or even future new features through the PC Interface (with optional cable). With Dual Algorithm and optional conservative factor settings, the Geo 2.0 may be programmed to provide no-deco and deco profiles similar to virtually every computer on the market.
