North and South Florida



Why do we ask about unit size & type?
We use this only for our own internal purchase info. The chips are all the same and are interchangeable between all compatible units.

This chart is provided on two separate Chips – NFL and SFL.  The dataset is too large to fit on a single chip.

As shown by the insets, Track coverage includes:

The entire St. Johns River system

The intracoastal waterway on both coasts and the entire Florida coastline

Replete coverage around Homosassa/Crystal River, Tampa Bay, Jacksonville, Fernandina, Flagler Beach, Mosquito Lagoon, the Indian River, Pensacola, Panama City, Lake Okeechobee and all substantive inland water features.

The Everglades and 10,000 Islands are fully covered.

All of the Florida Keys are fully covered approximately out to the reef line and also include, the Lakes Passage, Marquesas Keys and Tortugas National Park.


Tracks on the chips are from a different data set than the images provided in the example photos above which are for demonstration purposes.

FMT Chart Discounts for Customers Purchasing New Units

We receive lots of calls every month from Garmin, Raymarine, Humminbird, and owners on other platforms who are dissatisfied with their current charts and want to run ISLA but are unable because they are stuck with their current incompatible GPS.  Some of these boaters have new units as well just a few months old and are selling them to get a Navico unit to run ISLA. Given the substantive volume of these calls and recognizing how frustrated so many are having to deal with it, we have initiated a program which will allow boaters to purchase a current model Navico unit from ISLA at the lowest possible price and get a 20% chart discount.    Current Model Units that are 12″ and larger qualify to purchase ISLA maps for 20% off of the regular price.   Discount only available on current models and does not apply to discontinued models.
