North Florida


North Florida (North of Sarasota and Sebastian)

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.
Note: If you have a unit older than 5 years such as a Lowrance Gen 1 or Gen 2 unit a chip created with an older version of the programming software is likely required and you should call us to inquire and request one of those before ordering; chips created for the latest model units will likely have issues rendering chart vector features on the older units.  Conversely, chips created for the older model units will not work well with the latest model units.

Unit *

All ISLA charts are comprised of two things: Images and a Base Map with features.  The North Florida chart includes a base map with map features for the entire State but only includes hi res imagery for North Florida.   Thus, if you purchase NFL, you still receive a base map for SFL but without the SFL hi res imagery. The NFL imagery includes inland areas north of a line from Sebastian Inlet to N. Sarasota Bay and it runs to the Georgia and AL State boundary.

Track coverage includes the entire State as noted in the insets.

Track coverage includes the entire St. Johns River system, the Intracoastal Waterway, and the entire Florida coastline with replete coverage around Homosassa/Crystal River, Cedar Key, Steinhatchee, Horseshoe, Suwannee,  Tampa Bay, Jacksonville, Fernandina, Flagler Beach, Mosquito Lagoon, the Indian River, and the Pensacola and Panama City areas.

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