instead of that expensive korean one, why not look a little closer to home with miller. i have a digital elite and it has basically the same RF thing, they call it X-mode. it just senses the arc before its made, so it keeps the lense dark. you can also use this outside in the sun as it doesent effect it. i bought mine from indiana oxygen company for 280$. they are regular 380. its a great helmet, lots of designs....
