Detailed Marine Cartography

ISLA charts are the most accurate and complete inshore marine navigation and fish scouting tool ever created. Whether you’re fishing unfamiliar challenging waters, exploring a remote area, cruising the coastline or just looking for navigational help due to poor lighting conditions, ISLA’s Florida Marine Tracks and Louisiana Marine Tracks charts allow you to navigate virtually anywhere or anytime with confidence throughout Florida and eastern Louisiana with no guessing, no questions and no uncertainty.  

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).

Precise Navigation Tracks

ISLA provides thousands of miles of precisely drawn detailed navigation tracks that were run at low tide, making our map perfect for flats, bay boats, and other shallow-water boats running in challenging areas.  Other boaters in deeper drafting boats who can only run in bays, basins and primary marked channels also run ISLA tracks in those areas.

Map Accuracy

Our base map has been corrected to provide the current exact location of navigation aids, including daymarkers, buoys and signs.  Other features that are missing on other maps such as signs, posts, concrete abutments, PVC stakes and Everglades navigational aids are included with near to the foot accuracy.

Hi-Res Imagery

ISLA charts offer the best imagery available on any GPS platform.  The native imagery has resolution ranging from 3 inches to 1 foot and we processed it to allow you to zoom in with clarity to as good as 50’ to 100’ without your screen going fuzzy so you can see what you need to see.  The quality and clarity of our imagery is unsurpassed by any other gps chart.

Recommended Machines and Mounting for Best Performance

We recommend the largest screen possible .  12” units work the best with our product and are much better with ISLA charts than small screens such as a 7” which all have inferior screen resolution.  Screen resolution is important with our imagery. The imagery looks good on all the units but is much better on larger screens. We have hundreds of 12” units running ISLA charts on small boats including Gheenos and small side console rigs. if you run a small boat and think 12″ is way too large, think again.  The notion that 16’ and 18’ boats are best suited to small screens is fallacy.  Once you run ISLA on a larger screen you will never want a small screen again. Larger screens have the best resolution, are easier to see, provide the best situational awareness, and are easier to operate on the water when running.  If you do not have a lot of room on your console for a larger unit as is often the case, we recommend the use of a high quality adjustable mount such as Balzout or Cisco Fishing Systems which have small footprints and will allow you to float the unit over the console in a perfect position.  


All of the machines noted above including GO units and in all sizes run our charts just fine.  However, we don’t recommend any Simrad GO units because they are touch screen only and the 7 and 9 inch GO units have inferior screen resolution.  GO units are not the best choice for any highly detailed chart used to run inshore.  GO units are harder to use running in chop compared to any other machine with buttons/knobs and in our opinion offer zero practical advantage vs. any other compatible option.  ISLA customers manipulate their GPS far more often than users running other charts because when they do they get more information where as other charts don’t provide more information and people learn quickly there is only so much to see and in many cases nothing to see that is relevant on general reference charts such as Navionics or other Garmin products.  Therefore GO owners running ISLA are often frustrated with the continuous pinching and unpinching all day which becomes very tiresome.  GO units are less expensive for good reason.  View Compatible Units

With respect to mounting we never recommend any flush mounts for skiffs.  It can be acceptable on boats with larger consoles that have a more vertical mounting area.  High quality adjustable mounts such as Balzout or Cisco Fishing Systems are recommended as they provide the best functionality and adjustability and allow you to float your unit exactly where it needs to be as opposed to one static position and even one static viewing angle.  Ergonomics and accessibility of the screen is very important as ISLA customers find themselves zooming zooming in and out about 10 times more than they do with standard reference charts because with ISLA you can see what you have always been looking for and found missing on all of the other charts.  Therefore, the location and mounting of the unit is important.
