I am parting ways with my Nerd 1. I am selling it because I bought a NERD2, and really love it, so I won't be needing the NERD1 any longer. This is an excellent device, in great shape. Very clean, connector always maintained with mineral oil after every dive and stored disconnected per Shearwater maintenance instructions. Works perfectly, as if new. This is a great opportunity to own an amazing piece of dive gear. Asking $1400.00 plus you pay for your method of shipping. for an extra $25.00 I will throw in a rEvo DSV mount with the stainless steel plate that is pictured installed on the device. If you do not dive a rEvo I will remove this before shipment if desired. Optionally if you are in the South Florida area you can pick this NERD up and avoid shipping completely.
