Sonar class

Guys, I have been running the HDS Touch units for 2 years. I thought I was doing good until thursday when I took a sonar class with Randy Kuhens of Precision Sonar. This was a one on one, hands on class. My units have never looked so good. If anyone is thinking of taking a class I would recommend Randy. The class wasn`t over until I ran out of questions. Randy is a great guy and very knowledgeable with the Lowrance units. Plus he showed me how to locate fish with the Navionics maps. All I can say is it was worth the money.
