SHEARWATER NERD

The Shearwater NERD (Near Eye Remote Display) is the first technical dive computer with a display mounted on the diver’s rebreather mouthpiece. 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” TV screen 12’ away, with no need to focus. The display is unobtrusive as it virtually disappears when you look straight ahead. The numbers are there when you need them and out of the way when you don’t.

The NERD has an integrated, 3-axis, tilt compensated compass. You can oder it with a Fischer or DiveCAN connector.

The NERD has 6 different dive modes:

OPEN CIRCUIT RECREATIONAL: full-featured nitrox computer, up to 3 gases.

OPEN CIRCUIT TECHNICAL: up to 5 gases, Trimix enabled by default.

3 REBREATHER/BAILOUT modes: handles 5 OC/5 CC gases, Trimix enabled.

  1. CC-INT: closed circuit fixed ppO2
  2. CC-EXT: closed circuit external ppO2. Real time PPO2 monitoring of up to 3 O2 sensors.
  3. SCR-EXT: semi-closed circuit external ppO2. Real time PPO2 monitoring of up to 3 O2 sensors.

GAUGE: depth, time, resettable stop watch function, full dive logging.

Our personal note: if you dive CCR - that's the computer you want.

We recommend to use all dive computers conservatively and follow DIVERS ALERT NETWORK’s tips for a safer use of dive computers!
