I know you guys have some way of inspecting crawls and taking tools with you. Crawling around trying to hold a flashlight, moisture meter, voltage detector, TIFF, camera and PDA is kind of hard to do. Wearing my tool belt means everything spills out of it and gets kicked around and lost.
I was thinking about a backpack so I could just keep it zipped up until I need something out of it. What does everyone else do?
