Product Description
The Shearwater Research NERD 2 Fischer is a heads up (HUD) display, advanced hands-free technical diving computer for open and closed circuit divers. The Near Eye Remote Display (NERD) incorporates a powerful feature set, easy to understand menus, easy to read full colour display, and a special optics and mounting system that projects the equivalent of the Shearwater dive computer as a heads up display directly in the eye of the diver. 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.

The Shearwater NERD 2 Fischer is a full decompression dive computer incorporating the functionality of the Shearwater Research Perdix AI, but with a display mounted on the diver's rebreather mouthpiece or open circuit 2nd stage regulator.
Keep your eye on the dive, not on your dive computer.
This revolutionary device keeps crucial information in your line-of-sight for the entire dive. Thanks to the Micro LCD display and magnifying lens, the data appears as if displayed on a 32-inch TV screen 12-inch away, with no need to focus. If you can watch a TV without glasses, and even if you have a bifocal lens mask for reading gauges, you should have no problem seeing the NERD 2. 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-colour 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 Shearwater 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 Shearwater NERD 2 will NOT "lockout" after a missed stop or ascent rate violation.
Rebreather tested. Recreational requested.
Out of the box, the Shearwater 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 language menus and both imperial/metric units of measure.
The Shearwater NERD 2 is capable of wirelessly connecting to either one or two optional transmitters giving the diver ability to monitor up to two tank pressures. Air integration is optional for all modes, from OC Rec to CC/BO. The tank pressure(s), in PSI or BAR, and GTR can be displayed to the customisable slots on the main display screen or accessed through the underlying information screens. Enabling the AI feature causes approximately 10% decrease in battery life.
Bluetooth Integration
After the dive, the Shearwater NERD 2 communicates via next-generation Bluetooth Smart Ready with iOS devices such as the iPad and iPhone. In addition to current Shearwater and third party support for Mac and PC desktop applications, users are able to download dives using their iOS devices in conjunction with third-party applications.
Rechargeable Lithium Ion Battery
The NERD 2 incorporates a built-in lithium-ion rechargeable battery. Users can expect a minimum of 18 dive hours, on medium brightness, from a fully charged NERD 2 and 5 charges from the charge bank.
The NERD 2 connects to a charging clip which snaps on the back of the computer. The charge clip is splash proof.
The charging clip connects to any USB cable.
The USB cable can connect to any USB port or the power bank supplied by Shearwater. The power bank can provide 5 full charges to the NERD 2.
Included with every Shearwater NERD2 Fischer from The Scuba Doctor are a universal mounting clamp, recharging clip, charging bank, USB cable, Fischer 103 connector (plug compatible with the other Shearwater -EXT version computers), cap, and printed Quick Start Guide with instructions for downloading software from the Shearwater Research website. The software includes a complete dive log manager, compatible with both MS Windows and MAC OS X. The dive log manager supports log downloads and firmware updates via the Bluetooth wireless interface. An optional VPM-B unlock code enables using the Varying Permeability Model (VPM-B and VPM-B/GFS) algorithm for calculating decompression.
