We corrected all of the pervasive and long standing substantive shortcomings in all of the other GPS charts that inshore boaters find so frustrating including 1) the dated dark and missing low res images that are useless in so many areas and go fuzzy when zoomed, 2) the thousands of inaccurate navigational markers, and 3) the missing chart features such as the precise locations of dangerous obstacles including flats and bars, navigational posts, stakes, signs, local buoys, poll & troll zones, manatee zones and idle zones. And in addition, we added many thousands of miles of proven low tide tracks as an additional optional map layer so you can follow a track from virtually any location in any direction to any location. Explore without running aground or any lower unit damage.
ISLA provides detailed tracks that cover very shallow and remote inshore areas as well as primary deeper runs but due to the inshore detail provided ISLA’s charts are most popular with owners who run flats and bay boats that draft 13″ or less at rest. No other marine chart comes close to the accuracy or detail of ISLA charts. They are easy to load and compatible with most Navico chart plotters (including Simrad, Lowrance, and B&G units).
