NERD 2 Threaded Mounting Info
The same 2 hole pattern that was part of the NERD 1 is built into the bottom of all NERD 2 dive computers. This will allow compatibility with NERD 1 original mounts. It will also allow for the option of custom made mounts that could be created for masks, helmets, or full face masks. Additional detail for this can be found in the NERD 2 manual.
Rechargeable Lithium Ion Battery
The NERD 2 connects to a charging clip that snaps on the back of the computer. The charging clip is splash proof. The charging clip connects to any USB cable. The USB cable can connect to any USB port or the power bank supplied by Shearwater. The power bank can provide 5 full charges to the NERD 2.
