SonarCharts Before and After...Why Updating Your Maps is Important

These screenshots are from a wreck before and after it was mapped and updated for Navionics charts. The detail is evident, but the key is you could have bought a Navionics chip a month before this wreck was mapped and has just the wreck icon. If you updated your chip a week or so after it was mapped, you would have gotten this detail. It's juts one of the 2000+ edits that are made to Navionics maps every week.

More than wrecks, think about your local inlet or river, where the bottom changes a lot. Maybe a storm comes through and rearranges some rocks or creates new holes. Navionics is the only chip that lets you update the mapping to be able to correct for those changes quickly.
