HOG/EDGE Dive Computer

Regrettably, occasionally a unit would ship without any hole being drilled for ambient pressure to reach the depth sensor.

Actually you don't need to have a hole drilled to the sensor. When I design pressure housing for depth I usually include a flexible membrane that allows the internal pressure to rise with depth. In order to ensure membrane isn't stretched beyond its limits the internal housing is filled with mineral oil (non-compressible fluid). So now the internal pressure is the external pressure.

Seeing as my electronic housings go well beyond tech/rec divers limits the same principle can be applied to wrist mount computer. Actually I would be surprised if it isn't.

Awww, you're so earnest; that's nice.

Anyway, yeah, the more complicated the better. Why don't you go survey the various higher-end dive computers out there, and let us all know how often you find such a design?

We will be showing the computer at DEMA. It's be doing validation trials.

Being a clean sheet design and something COMPLETELY new for us it's been a pretty big project.

This, however, is interesting...having watched the Atomic Cobalt evolve, I've no doubt it's a big project. What's the design thinking/target market? Rec nitrox only or will there be more gases? More open-ended control over things like gas settings and conservatism during a dive like Liquivision or Shearwater, or more structured like rec computers (set it in advance, can't be altered during dive)? What algorithm(s)? What's new/special about this new design?

I still love the Edge Epic regs I have and really, really, like the new Hog Zenith. Good stuff....good price and awesome quality and service.

I'm looking forward to seeing the new computer. I expect to be impressed.
and I may have to check with my Hog/Edge contact on getting one if I like it.....

Point of fact it is a simpler design as any penetration in a pressure housing greatly increase the chance of failure. As for how many employ it this technique I'm not sure, but next time I have a couple grand to blow I'll be sure to tear apart a couple Shearwaters and Liquivisions k?
