Is there anything on Kerbin that the scanning arm works on?

[jpinard]

I tried to scan the ground, a tree, grass, and the Squad monolith but nothing works so far.  Is there anyone this arm thingie can be used on Kerbin?

If you're not using a new save, the breaking ground landmarks will not load. This may be the issue. I may be wrong. There should be many Boab tress scattered across the greeny parts of kerbin. Impossible to miss.

So I should be able to scan Boab trees?  This is a fresh install with all the DLC and I'm doing the career.

Then yes you can scan the trees. I do not believe all trees are scannable. If you can walk through them they're not the right tree.

Drive or fly into the grasslands west of the KSC and look out for the big trees. Then keep going into the mountains and look for some unique features there too.

That's correct. If you set scatterers to nil. Only the Boab trees will be on the terrain. Unfortunately for my potato this is my native graphic setting.
