Query: Streamline estimation of large-scale projects.

The scale master makes it so easy to do big take-offs. Run this little guy along walls of similar types, piping, sidewalks, borders. It has architects and engineer scales, you can change and lock in the scale on the fly.The only reason that its a four rather than a five is that the little toggles are kind of rough on the fingertips. This doesn't detract from the usefulness of the product a bit though.
