The Shearwater NERD 2 is the world's first near eye remote display dive computer and has been designed for enhanced flexibility and reliability. It is a full decompression technical dive computer but also supports recreational divers with a simplified menu structure and options. This standalone version is perfect for open circuit divers that want to experience the freedom that it has to offer.
The universal regulator mount allows divers to secure the NERD 2 within their line of sight and dive with the security of knowing their crucial dive information with a glance of the eye. You might think that the display would be small and difficult to read but the combination of the Micro LCD display and the magnifying lens, the data on the NERD 2 actually appears as if you were looking at a 25" TV from 12 feet away.
Due to the design of the computer, fiddling with too many buttons would be difficult so Shearwater have added a simple navigation system that uses a state-aware menu structure.
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 NERD 2 can be upgraded to support up to two wireless transmitters free of charge with a firmware updated obtained directly from Shearwater (firstname.lastname@example.org).
The NERD 2 is powered by a rechargeable Lithium-ion battery which gives a minimum of 18 hours dive time on a full charge (based on medium brightness) and will recharge in approximately four hours. The battery can be charged from any USB port or power bank.
The recreational open circuit mode (Recreational Nitrox mode) includes a simpler menu structure, less cluttered display with a larger font and configurable bottom row, optional safety stops, and a no-decompression limit dive planner. The simplified settings allow for three breathing gas mixtures (Air or Nitrox) and places a greater emphasis on the maximum operating depth (MOD) and no decompression time limit (NDL).
The display prominently warns the diver if their depth is near, at or exceeds the MOD of the selected breathing gas. The diver also simply selects one of three levels of NDL conservatism and during the dive a bar graph turns from green to red as the diver approaches the NDL. An optional 3-minute countdown safety stop starts when the diver reaches shallower than 20ft / 6m on the ascent. If the diver exceeds the NDL and requires stops, the display turns red and warns "DECO STOP" with the mandatory depth and stop times.
