Why would I want to be constantly running back and forth to fetch tools? That is the definition of professional? I use a small electricians pouch on a tool belt. Along the back there is a camera case. I use every tool in the pouch with the exception of the razor knife on every inspection. If I am heading into the attic, I am likely to need a moisture meter, a nut driver for the HVAC, a camera, a probe, and a flashlight. So I rummage through a tool box that is filled with all kinds of who knows what looking for the correct assortment of tools to cram into the pockets my pressed slacks. Once I get in the back dark corner of the attic, I realize I forgot the XXX or some tool falls out of the pocket to be swallowed up by blown insulation. That makes me more professional? I think that lugging around an oversized tool bag filled with gadgets that get used once every fifth inspection that I have to constantly bend over, tote to the next drop location, rummage around looking for the tool, and then begin to inspect the room less professional. I say it gives the impression you have a bag of stuff because you cannot organize yourself enough to carry just the essential items. Maybe I just don't have enough gadgets to be a professional home inspector. Lets just say I disagree with your assessment. Happy future back problems... just wait... I was fine for the first 10 years, then the ole' bod just started protesting... I have concluded it isn't a matter of fitness or conditioning. It's just that subtle off balance weight tugging at your core alignment for hours each day. Eventually, it wins...
