The sleek and easy to use Oceanic VEO 4.0 is a great all-around wrist dive computer for both novice and more experienced divers. Packed with advanced features, such as Bluetooth connectivity and integrated mobile experience through the DiveLog App, the VEO 4.0 still maintains Oceanic's outstanding level of affordability.  
The device has 4 operating modes: Air, Nitrox, Gauge (with run timer) and Free (tracks calculations to allow switching between NORM and Free). 2 operating buttons allow “step forward” and “fast scroll” interface for streamlined access and setting of personal options. The computer comes with features including a full menu of audible and visual alarms for everything from nitrox settings to depth, time and deco status. You also get a backlight function (you set the duration) and the option of downloading your profiles to a PC. 
Compared to its predecessor, the Veo 4.0 features bolder larger, easy-to-read digits, and has well-designed bar graphs to make monitoring your ascent rate and nitrogen loading easy. Traditionally, though, the Veo 4.0 is powered by Oceanic's Exclusive Dual Algorithm - you can choose from the Pelagic DSAT or Pelagic Z . 
The Computer comes in a durable rubber impact resistant wrist boot and has a user replaceable CR2450 battery with a battery life of approximately 300 hours.
