Red Laser Spots the Ground
The helmet is just about done; video below. The picture above shows my spotting laser, which will be a useful reference to spot the ground and sea ice as I fly over them in the paraglider. The helmet has to deliver dry air, and exhaust moist breath, lest that breath condense on the visor, freeze, and block my vision. No oils, or other goop I've used, in many Arctic treks, has ever prevented this, so it's critical to make this work. Huffing and puffing in the helmet, I'm still getting some fogging, and that's no good. I have to get it completely sealed up. One breath on the visor, and I'll be blind. Can't fly with the visor up, because windchills will approach -100F. And that'll freeze your eyeballs, matey!
