Navionics is launching their new SonarCharts for Garmin chart plotter products at the start of 2015. SonarCharts for Garmin is one foot contours of all our 18,000 Navionics lakes and coastal areas out to 80 feet. Beyond 80 feet in saltwater is 3 foot contours to 250 and 6 foot beyond that. This is meant to give more fishing and sailing/cruising detail on your Garmin chart plotter. There have been several regions made available and are more being made available daily. Navionics would like to send out some free samples to the first 20 Garmin users to respond so we can receive feedback. All areas have not been finished, but even if your area is not available yet, you will be put on a waiting list and sent a free chart as soon as your area is made available. Please PM the following details: name, email, mailing info so we can send you a beta sample to test and provide us with some feedback and region you fish. This is a great benefit for Garmin users that has never been available before and will allow users to have the same mapping resources as other brand chartplotters.
