Petrel 2 OC/CC Trimix with External CCR/SCR Monitoring 

The Petrel2-EXT includes a Fischer 103 I/O port used for external PO2 monitoring of up to three oxygen sensors in a rebreather loop. Once the Petrel2- EXT is plugged in to the sensor cable via the Fischer 103A connector and calibrated it uses the PPO2 input from the sensors to determine the system average PPO2 used for decompression calculations and CNS tracking. A voting algorithm is used to decide which of the three sensors are likely to be correct. If a sensor matches either of the other two sensors within ±20%, it passes voting. The system average PPO2 is the average of all sensors that have passed voting.

Near Eye Remote Display 2 - Fischer

The NERD is a full decompression dive computer incorporating the functionality of the Shearwater Research Perdix-AI, but with a display mounted on the diver's regulator second stage. This revolutionary device keeps crucial information in your line-of-sight for the entire dive. The display is unobtrusive as it virtually disappears when you look straight ahead. The numbers are there when you need them at any point during the dive, and out of the way when you don't. The full-color display is used to convey additional meaning with the information being displayed. When information is yellow or red, it calls the diver's attention to an unusual value or problem.

During a decompression dive, the NERD 2 provides complete information displays of all required stop times. The NERD 2 can provide time-to-surface based on "look ahead" at planned gas switches. Multiple gas definition presets are supported with any combination of oxygen, nitrogen, and helium. The NERD 2 will NOT "lockout" after a missed stop or ascent rate violation. Out of the box, the NERD 2 includes open circuit and closed circuit Air, Nitrox and Trimix mixed gas functionality along with several enhanced navigation features for the three-axis tilt-compensated digital compass. The standard firmware supports English menus and both imperial/metric units of measure.

Near Eye Remote Display 2 - Fischer

The NERD is a full decompression dive computer incorporating functionality of the Shearwater Research Perdix-AI, but with a display mounted on the diver's rebreather mouthpiece. This model incorporates a Fischer 103 I/O connector (plug compatible with the other Shearwater -EXT version computers), for integration into rebreathers for primary or redundant PPO2 monitoring with full decompression. This revolutionary device keeps crucial information in your line-of-sight for the entire dive. The numbers are there when you need them at any point during the dive, and out of the way when you don't. The full color display is used to convey additional meaning with the information being displayed. When information is yellow or red, it calls the diver's attention to an unusual value or problem.
