I got a lot of questions during my webinar last week about making maps via #SonarChartLive. It is very easy and the technology is amazing. It involves connecting my Navionics app in my phone to my Lowrance HDS 12 via the wifi. Here are some pictures from San V in San Diego. This map was made by Sonar Logging. The map is available to upload for those who have a Navionics chart/chip or via the FREE webapp on www.navionics.com
