Actually, it is continuously *calibrated*, not only validated!
True! I'm would really love to read that paper about it.
I wonder if they bother with a negative pressure test in the pre dive checks? Have a hard time seeing how the unit could perform that on its own, since they don't mention that the user must perform this.
Also wonder it its true that it has an electronically controlled dump valve? Didn't they mention something about that, despite us not finding any external signs of one?
