@sorcerer44 sorry I nearly forgot to address this to you mate:-
I can't think what it is called, but there used to be a little guide somewhere online that listed the different types of spectral signals you see on the wave scanner (the buggy's radar jobby). It also gave sample sounds as they all differ. After doing it for a while you'll get used to which is which but I found it took time to learn them.
Maybe someone after me will still have it bookmarked, but try a Google search for the wave scanner information, sounds and visuals - something along those lines. It's incredibly helpful.
Iirc, any signal will only resolve into a white blip on the normal radar, when it is around 250-300m from the buggy. But the wave scanner will show things that are a couple of km away. When you see something you want on the scanner, turn to put it in the middle of the scanner and keep going. The band will get narrower and narrower, often overlapping with others, and you'll eventually get a really strong narrow band visible. Then it will resolve into a white blob on the radar.
It's worth trying to find the most common four signals using the scanner if you want to get good with them. By common, I mean the ones to shoot for engineering materials. Iirc, they are Outcrop, Bronzite Chondrite, Mesosiderite, and Metallic Meteorite. Find a signal by eye and sound on the scanner, go towards it, and try to figure out what it is before you get there. You'll get better at discerning doing it this way. Be aware that if there's more than one thing nearby though the signals will merge a bit until you close right in. You can also sometimes see them visually before the white blob appears. And the met meteorites will normally show as groups of 3, these are the most lucrative for mats!
I hope this helps, but it is daunting to begin with, so stick at it o7
