Open Circuit Air and Nitrox
The VR3 HD Dive Computer from VR Technology Ltd (formerly Delta P Technology) is the most advanced dive computer available and it's unique upgrade capability keeps it on the cutting edge of technology. The VR3 is a next generation dive computer, with interactive tools which meet the needs and match the diving profiles of demanding divers who want the advantages of high-technology to accompany them underwater.
The VR3 is a full decompression dive computer incorporating a derivative of the Bühlmann ZH-L16 algorithm with modifications to support deep stops, adjustable shallow stop depth, and dynamic decompression ceilings. An optional upgrade allows switching between the Bühlmann ZH-L16 and Varying Permeability Model B/E algorithms. During a decompression dive, the VR3 provides complete information displays of all required stop times. The VR3 can provide time-to-surface based on "look ahead" at planned gas switches. The VR3 will NOT "lockout" after a missed stop or ascent rate violation. The VR3 upgrade options also provide outstanding support for semi-closed and fully closed-circuit rebreathers.
