Oceanic Geo 4.0 Dive Computer

The Oceanic GEO 4.0 Dive Computer represents the pinnacle of innovation in the Oceanic series, succeeding the highly popular Geo 2.0. Combining functionality, durability, and style, this watch-style computer offers four versatile modes - Air, Gauge, Freediving, and Watch - catering to various diving activities seamlessly. 

The user-friendly four-button navigation system ensures effortless access to its comprehensive set of features, including gas switching with EAN Nitrox from 21% to 100%, a dual algorithm, and crucial underwater metrics such as temperature, depth, safety stops, ascent alarms, and bottom time tracking. Notably, the Geo 4.0's diver-replaceable batteries contribute to cost-effective maintenance, although it is recommended to have a service technician handle the replacement to ensure proper sealing and pressure testing.

Offering a generous 24-dive log memory, the computer allows users to conveniently review past dives on its display, or alternatively, transfer this data to their smartphones via Bluetooth.

Before you can transfer the data across, you will need to download the appropriate software depending on if you are using a PC or MAC.
