The equivalent of a hammer for a carpenter. This is the most used tool for any home inspector. I use this to check for correct wiring on US power outlets. The outlet tester is used to verify that the outlet can provide power to a device plugged into it
I use this tablet to give state of the art inspections with this i use InspectIT as my home inspection software.
I use this camera to get to areas I normally could not reach. Especially in tight crawl holes this allows me to inspect behind ducting, plumbing that might be in the way. Also with this i can look into the gable vent in attic areas to give a better description of whats being inspected.
I use this when determining cooling or heating performance of HVAC equipment.
I use this to determine the moisture content of wood and other building materials (like drywall) or check water damaged areas to see if moisture is still present.
I use this to locate the source of explosive gas leaks including natural gas, propane, fuel including gasoline or kerosene
