Equipment Question

Hello Everyone,
I’m new to this. I have 27 years in construction and materials but new to this end of the industry. I’m attempting to sort out what I actually need to hit the ground running. The obvious tools and equipment are fine but are Thermal imaging systems or mini Infrared Thermometers items that get used with any regularity?
Is anyone willing to jot out a list of mission critical items that every good inspector has with him/her.
Thanks in advance!
