Shearwater NERD 2

  • $2,100.00

The first hands-free display for divers has been redesigned for increased flexibility and reliability. In addition to the DiveCAN and Fischer versions, open circuit divers can now experience the freedom that the NERD 2 offers. The universal regulator mount allows divers to fix the NERD 2 within their line of sight and dive with dive sites always in sight.

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