Shearwater NERD 2 CC Mount Kit
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. This is a CC mount, suitable with most rebreathers. The mount diameter is adjustable to { 2.2 - 2.4 in | 55 - 61 mm }.
