I can have all of this, i have a good environment and a separated clean space in my farm, its just to know where to start and what to buy and so on.
Obviosully I don't know what is inside the paid that course, my guess is that there is nothing worth buying in there, you can find free tutorials both videos and written format in
https://www.zeusbtc.com/ the list of tools can be easily known by watching one of their videos fixing a miner, it's mainly
1- The fixture tool
2- A multimeter ( some specific models)
3- Heatgun
4- Solder paste
Those are off the top of my head, watch the videos and write down all the tools they use.
It doesn't need this course if he knows the basic things about Electronics and I think the other guide inside the course I think is how to flash the miner with SD card and how to upgrade the miner through web GUI.
He will need some repair kit for repairing like this image below.
For hardware related issues and SD card for software and fixture tool for diagnosing.
