The world’s first near eye remote display for scuba divers has been redesigned for enhanced flexibility and reliability. In addition to the DiveCAN and Fischer versions, OC divers can now experience the freedom the NERD 2 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.

From the combination of the Micro LCD display and the magnifying lens, the data on the NERD 2 appears as if you were looking at a 25 inch TV 12 feet away.

NERD 2 Mount Options

An important and unique feature of the NERD 2 dive computer is that it requires a mount to keep it properly positioned. The NERD 2 is packaged with either a mount option for a closed circuit rebreather or open circuit regulator.

The same 2 hole pattern that was part of the NERD 1 is built into bottom of all NERD 2 dive computers. This will allow compatibility with NERD 1 original mounts. It will also allow for the option of custom made mounts that could be created for masks, helmets, or full face masks. Additional details for this can be found in the NERD 2 manual.

Rechargeable Lithium Ion Battery

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.
