Here’s a free sample chart that shows how we use side-scan sonar to map out a cool ledges in state waters near St. Pete.
We use high-resolution side-scan sonar data to search for cool structure. When we find something, we mark up the spot, give it a name, and then trace out the structure with simplified lines. Then we convert these lines and points into electronic chart files that can be downloaded directly into your boat’s GPS.
This free preview is only available in Google Earth KMZ format. For GPS/Chartplotter formats, check out our full St. Pete Nearshore chart, which marks more than 400 great fishing spots in this same area.
