Hammerhead electronics may NOT function properly during a nuclear explosion!

Chisana · 29th March 2008, 23:44

I was at Beneath The Sea today, and found out from scientific literature being distributed by Inner Space Systems (ISC) that advanced testing performed on the Hammerhead revealed some failures when subjected to an Electromagetic Pulse (EMP), most commonly associated with nuclear explosions!

Therefore do not dive this unit while nuclear explosions are underway nearby! The secondary may exhibit intermittant false readings!

Wrap it in foil. Easy.

I was wondering how long it would take before the shit throwing would start, well lets see where this goes

Hey now! If there is a nuclear explosion nearby, I will be more worried about my ass than a damn faulty secondary display.

sounds like a good reason for Eric <mempilot> not to switch to an optima......

As i undersand it his is on its way, bit late to cancle now.

My Shearwater went down yesterday and my first thaught was it may have been a nucular strike on Detling village hall? It turned out to be water in the Fischer conector. So good news for the badminton club

Doesn't underwater welding involve EMP fields as well?

I believe what they were testing was electrostatic discharge (ESD).

I'm not an engineer, but I would have never have thought to worry about a little static electricity while I'm underwater (lightning excluded). I think if you were exposed to enough voltage/current to fry your electronics, you'd be zorched too, so is this really an issue?

How about you have been sheltering in the boats cabin in your polyester undersuit and then wander out and pick up your handset that has had a dose of salt water over it. You discharge your static to earth through it from your body through your finger? From what was mentioned earlier, man-made clothing can apparently generate substantial kV levels of static and it therefore seems a not unrealistic test of the unit.

I don't think the commercial ESD standards are aimed at making the unit resistant to nuclear war - just everyday life - protecting the uninformed consumer's interests. A good way of deflecting a bit of unwanted flack though!!

No wander, Kevin has the best package deal. All in One, price - performance. Best looking hardware and desent electronics, IMPO. No add-on b...$h!t. 10,5k delivers it all, quality and redundancy. <img>
Looking forward to change my modified Evo for HH Rebreather as soon as funds permiting.<img>

Cheers,

P.S. On another thought. Do you want to have a painfull death on the surface?!?<img>
