It still has the guide cards for how to read it for different types of valves, etc... I found it in a small town store, outside Nashville, TN, USA, picked it up because I haven't seen one of these before. A little tedious to use, but, it is more capable than I would've thought. Thought someone other than me might think it was neat.
