If not, I think it should.
I have seen the same with immies being able to find it without an issue.
What problem do you see it creating?
From my perspective, it allows further differentiation between techs. I
t also opens up more avenues for success. Maybe a tech doesn't have a tech skill high enough to keep their gear from being pulled down, but if they can hide it well enough then they could still be useful.
Also I think that one of the current tools in the game could be updated to help locate well hidden devices. Maybe not to the point of being able to Uninstall or deface them, but at least to know that the device is there.
That knowledge of the device being there, combined with the upcoming hacking / grid integration would mitigate the benefits of well hidden devices.
