Sonar Ruler

This sonar ruler application was very confusing and frustrating . What a waste of $0.99. I deleted this App. To bad the seller did not provide the video explaining how it works prior to having to buy it. If I had viewed the video first I would have declined buying this sonar ruler. I think the person explaining how to use the sonar ruler on the video seemed a bit confused as to how to use it.
