You're probably correct about the wand, but I don't believe McCoy ever used a tricorder. If memory serves, he placed patients under a device with the Gian monitor.
I believe the tricorder is a TNG thing, especially since it seemed to composed of three parts.
Plus Space Above and Beyond, Farscape, Lexx, Quantum Leap, etc.
There were more but I won't bother listing them. I know you guys have a limited length to the list but why THREE Star Trek series? Damned trekkies. ST: Voyager is a waste of space in the list.
What? No Earth 2?
More important is - why aren't men going into teaching? Much more concerning
In the US and Canada, reportedly, male teachers often find public schools to be a hostile environment. That is why the number of teachers increases the older students, and you see a higher percentage of male professors than female professors.
The camoflauge part is bullshit too. it's not an advanced function. It's a very low level one that happens to work well, but is extremely low in the neural function, not even getting close to the brain.
Cephalopods have brains?
