It's more than just weight. I can make a scoop that weighs less than a pound (.4 kilos). But it wouldn't hold up to the abuse I'd give it.
I run the RTG travel scoop, because it breaks down and fits into my suitcases. That's pretty critical. It comes in at 4.5lbs. (2 kilos). But it's ROCK SOLID. I'll probably wear out before it does.
Curious question... why the focus on weight so much? Don't you just drag it behind you while you walk? Unlike a metal detector, the scoop weight isn't nearly as fatiguing.
But... if you're looking for a lightweight sand scoop that holds up. This one is less than .9 kilos:
