This products Overview

The Shearwater Research NERD 2 DiveCAN is a heads up (HUD) dive computer. 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 connector to support CAN bus technology for integration into JJ, O2ptima and Prism2 rebreathers.
