Nerd and petrel vs 2 petrel

Because my testosterone level is so high; and I'm on the way to being certified MOD2 from all the valuable info on this forum.

I dive OC. CCRs are like riding a Penny-farthing around London.

More like riding an electric pushbike. So much easier to do big and long dives, but cost more and need much more planning and preparation

If you’d dived one, you’d realise the fallacy of this statement.

What’s the difference between MOD1 and MOD2? Not a lot in reality, but a chasm in terms of skills, planning and risk.

Keep the info coming.

Keep the info coming.

The good news is the community benefits even if you don’t

NERD by a large margin. Setting the cost aside, there are no downsides to NERD that I can see.

I am right eye dominant and have NERD on the left DSV side; Petrel is on the left wrist. The configuration allows me to easily read info across the computers but only if I choose too. NERD is not intrusive for me. I say "for me" because it could be intrusive to someone else due to physiology.

Based on the feedback about the stock mount, I ordered an adjustable one that comes w rEvos. Happy as can be!

Except that the depth sensors are prone to breaking because of the design, and that you can’t see it in a proper turd hits the fan no viz situation (unlike some of the HUDs). It works for some people’s use, particularly those not scootering a very long distance, but I wouldn’t pretend there’s “no downsides,” as you say.

Try using a Nerd when bailed out. It’s nigh on impossible and very inconvenient.

No viz will be a problem with any computer I guess, not specific to NERD imo. Why is long distance scootering a problem in your opinion? Did some scooter trips and I liked it a lot better than the Petrel on my left. Just curious.

Bail out is a pita when it comes to NERD. In my opinion NERD is not usable anymore, meaning too cumbersome to use. Luckily we don't have to bail out that often

@beldridg is a big supporter of the Nerd on a rEvo and has written and posted on his blog a bit about It.

Me I'm a cheapskate and just went the dreams and HUD.

My main thinking was redundancy and simplicity on expedition trips such as Bikini (planned for next year). So I would manually dive my unit if I had a controller failure using the dreams to read 4 cells. However I have had my share of troubles getting used to the bulky dreams, especially whilst diving with gloves. I have clipped stages off to them, unclipped stages, dropped stages, it was an expensive learning process.

The dreams now clip off to a set of UK Sump drop-down D rings on my waist for my BO bottom gas and deco gas stages.

Not sure how to read your post. NERD and HUD are on the loop. When the loop is off, yeah, you can't see the computer. But you've already bailed, it is not like you need to monitor your PPO2. You still have Petrel and potentially, other computers.

What am I missing? And yes, I've bailed out w NERD.
