The Shearwater NERD 2 is a sophisticated dive computer that offers a range of features for divers. It's known for being the world's first near-eye remote display for scuba divers, redesigned to enhance flexibility and reliability. This device is particularly innovative due to its mounting system, which allows it to be secured within the diver's line of sight, whether they are using a closed circuit rebreather or open circuit regulator. This ensures that crucial dive information is always easily accessible.
Key features of the NERD 2 include a rechargeable lithium-ion battery, which provides a minimum of 18 dive hours on a full charge at medium brightness. The typical battery life is around 5 years or 500 charge cycles. The device connects to a charging clip which is splash-proof and can be connected to any USB cable for convenient charging.
Divers can choose from multiple diving modes tailored to different diving needs. These modes include Open Circuit Recreational, Open Circuit Technical, Closed Circuit/Bailout, External Monitoring, and Gauge mode. Each mode offers specific functionalities such as trimix capability, real-time PPO2 monitoring for semi-closed rebreathers, and full dive logging.
The NERD 2 also boasts a two-button interface for easy navigation, an optional 3-axis, tilt-compensated digital compass available in all modes, and AI functionality for displaying tank pressure (transmitter sold separately). It integrates Bluetooth® wireless technology, enabling communication with various devices and the Shearwater Cloud, for dive log analysis and more.
Its mount options are versatile, maintaining compatibility with NERD 1 mounts and allowing for custom designs. The dive logging capability is comprehensive, allowing divers to review and edit logs directly from their phones or tablets across various platforms like iOS, Android, Mac, and Windows.
Technical specifications of the NERD 2 are extensive, supporting various modes and features like multi-gas trimix decompression, closed circuit fixed PPO2, and optional semi-closed monitoring of PPO2 for 1-3 O2 sensors. It's compatible with different gas types and includes decompression algorithms such as Bühlmann ZHL-16C with Gradient Factors and optional VPM-B.
The NERD 2's design is both simple and powerful, offering line-of-sight information delivery, customizable settings (including screen flipping and firmware updates via Bluetooth), and a robust dive logging system. The device's full-color Micro LCD display and magnifying lens create an effect akin to viewing a 32” TV screen from 12 feet away, ensuring clear visibility of all necessary information.
