Shearwater have produced the NERD (Near Eye Remote Display), a fully self contained CCR HUD. It attaches to your CCR head by Fischer cable and has a user replaceable battery.You get real data such as PO2, CNS, depth, time, gas, required stops and deco obligation. This image is like reading a Petrel that is about 36cm (1 ft) away.
These are great tools for safe diving. If you need a more conservative reading, these computers will allow that. These are the computers to take you safely into OC or CCR tech diving Ì and get you safely back home again.
