NERD 2 – Heads-Up Display Dive Computer for Serious Technical Diving

The Shearwater NERD 2 is a compact, eye-level heads-up display dive computer designed for technical and rebreather divers who need critical information without ever looking down at a wrist or console. Mounted directly to a regulator or loop, the NERD 2 projects a sharp, high-contrast micro-display that appears as a large, virtual screen floating in your field of view.

With full trimix capability, advanced decompression support, CCR integration, and customizable layouts, the NERD 2 delivers immediate access to depth, time, decompression status, PPO?, and gas information—ideal for divers operating in overhead, low-visibility, or task-heavy environments. Rugged construction, long battery life, and intuitive navigation make it a trusted tool for expedition-level diving.
