Phil, As YOU've already stated, the first and most important tool that you can carry with you is YOU. It doesn't matter what tools YOU have or how fancy or expensive they are if YOU don't know how to use them, what they might tell YOU, and perhaps most importantly, what they can't or don't tell YOU. YOU are the person who will decide what tool to use in what circumstance, YOU will determine what YOU see after using the tool. You will choose what language to use, and how to say what YOU have seen. YOU have to make the decision as to the type of report to give and when to give it, as well as make the decision to use complete sentences, abreviations, or check marks. YOU are the person who will have to communicate very clearly what YOU have found to whomever YOU are working for. It's a never ending battle for most of us because as we become better educated and more experianced we realize that we will never ever be a Mark, Mike, Jerry, Douglas, or one of a few hundred others that we consider very knowledgeable in this field. We wipe the sweat from our eyes take a deep breath and try to follow where others have gone. Try to find an experienced inspector that will allow you to carry their ladder for a day. It will be worth it. YOU will be glad that YOU are getting to know the greatest tool in your bag...YOU.
