NERD2 question.

[Aaron Harmon]

Out of curiosity, why would you want to use a nerd on OC?

I use one for OC and love it. They are pretty fantastic.

I love mine on CCR. I can't imagine why you would want it for OC, especially if you didn't have a double hose regulator. It exists because rebreather divers need to continually monitor their PO2. There isn't any reason to be constantly watching your computer on OC.

But I guess if it's your only Shearwater, why not. I think that if I was in that situation, I would just bungee it to my wrist....

What happens when you need to donate your long hose?

I assume you have a back computer on your wrist?

There's also helmet mount...

I did not know that. I'm still not seeing the benefit of having a nerd for an open circuit diver. For the cost of a nerd you can buy two shearwater Perdix or teric.

Granted I'm not the most experienced diver, we arent monitoring a loop, and I have never wished to gave my computer in my face .

Brian Kakuk was dives an original NERD helmet mounted and has been for a long time. It lets his old eyes see the computer much better than on a wrist. It's ideal for working dives where you need your hands doing things as well. He's using gopro hinges on his, so he can loosen one and move the whole thing out of the way when he doesn't want to see it. The brick is on the back of his helmet. He's been using this since before he went to CCR though, so while this one is plugged in to his sidekick, if he's diving OC he still uses the NERD. It's a reasonable option for OC diving, especially sidemount.

^^^ Exactly what I was referencing.

I wear a perdix AI as a backup. As to the benefits, I like it. It is as simple as that. It allows me to focus on the dive itself. As to the cost, I live in northwest Ohio. Everything that I do short of diving in cold, murky quarries is expensive. I make several trips to the Caribbean every year. The cost of the Nerd was... I hate to say negligible, but given what we spend each year on diving...

@broncobowsher You can't buy the controllers separate from the rebreathers

My XCCR came with one controller and I purchased a second controller that I normally just use as a monitor. But if I happened to be on a trip and had a controller failure I could just swap it over to the controller bus and be back in business. It is a bit more expensive than a monitor unit.

you can buy replacement controllers obviously, but the controllers are only available from the manufacturers for their specific rebreathers. I.e. DGX is not allowed to sell an O2ptima controller, only Dive Rite can do that.
