I need help scanning hotspots?

[CyberBatty7]

How do I switch my scanner from mineral to power hot spots please?

You can't "switch modes" It automatically detects the closest resource, whatever it is. If you're not finding what you're looking for, move away from that resource until it detects another one.

Two additional points:
1) If you follow your scanner right up to the hotspot, it will automatically start analyzing the hotspot - mainly to tell you how strong it is and how much it will produce.

2) I know of no way to 'choose' what you look for: What you find is what you get. You literally have to 'circle' your base and see what the game has given you.

When I find a good planet that I would like to put a 'shelter' base on (somewhere to go for some special resource, for example), I will literally hop on my Exocraft and ride all over looking for a Power Hotspot. At that point, I drop my Base Computer, followed by my Power Generator, then I can put down my base.
