Why do asteroids containing nothing but a couple of water deposits show up as brightly as motherlodes on the pulse wave scanner? This is silly. It's like looking for a needle in a haystack using a scanner that makes some of the hay look like needles. It's feast or famine. You either find a motherlode worth a ton of money, or you find nothing that's worth the space it would take up in your cargo hold. I feel bad for whoever developed the sub-surface mining tool. FDev might as well have just thrown their work in the trash. I would like to try sub-surface mining, but I haven't found a single sub-surface deposit that was worth the space it would occupy in my cargo hold. When you prospect an asteroid that looks as bright as a motherlode on the pulse wave scanner, it should at least have some kind of consolation prize that would be worth the time it would take to collect it.
