The Veo 3.0 offers a choice between Pelagic DSAT (Spencer/Powell data basis) or Pelagic Z+ (Buhlmann ZHL-16C data basis) algorithms, so divers can switch between the two to create the best fit for their current diving needs. The system can handle two nitrox mixes, both up to 100 percent O2, and its three operating modes — Normal, Gauge and Free — cover all the diving bases. Other goodies include a Deep Stop feature, countdown timer, SmartGlo backlighting and the ability to download software updates.
