Do you want to learn how to read your Structure Scan or Side Imaging better? Here is a great example and explanation of graphing down a ledge with my Lowrance HDS Pro12 with a 2-1 Active Imaging Transducer while I was out looking for bass on a recent electronics class at Sam Rayburn. I’ve got days available in August and September if you are interested in on the water instructional classes or simply want to go catch some fish. #lowrancefishing #sonar #bassfishing #fishingtips #fishingguide | Cla
