Navionics Gold
There are three sizes, XL3, XL and Small. Whats the difference, besides the obvious one of area of coverage? Do the small ones have any more detail or are they just smaller? Any other differences between them other than coverage area?

I cant' speak for Navionics, but with C-Map you get different/additional charts with lower scales (more detail) with their "Super Wide" set than you do with "Wide" and "Local". Look closely at the NOAA charts included with each bundle of Navionics charts - I would'nt be surprised if they do the same as C-Map.

The XL3 cards have the same amount of information as 3 XL cards. The XL cards have the equivalent of several Small cards on them. If you go to the Navionics website, it will show you each chart that is included on a specific XL3, XL, or Small card. There is no more or less detail on any one of the different cards.

The differences relate to the capabilities of gps/chartplotter that use the cards. For instance, the Furuno 1650 and 1850 cannot use the XL3 charts. The Navionics website also tells you which cards can be used with various brands and models of gps/chartplotters.

For instance, I just bought a Furuno 1850, and I boat and fish in the Lake Erie, Lake Michigan and Lake Huron. If the 1850 accepted XL3 cards, I could get one card that covered all three lakes for $199. The 1850 cannot use XL3 cards, however, so I have to buy three separate XL cards, one for each lake, for $199 each.

Thanks for the info. That's what I was thinking was the case after reading the website. Just wanted to make sure.

Hi folks,
'Size' catagories can be confusing. I can not speak for Navionics but would like to clarify C-MAP cartography regions:

Local+, Wide+ and SuperWide+ indicates the pricing catagory. Generally speaking, these 'Precision' cards all have the same level of detail (the highest), just over larger or smaller geographic area. More geographic coastline covered with "precision detail', greater price. The exceptions are under the category of 'Pro-Angler' (also referred to as Fishing or Bathymetric) or ICW.

The Pro-Angler cards are for offshore fishing and include all the bottom contours but little harbor detail, while the one ICW card (NA-C307 ) is specialized to include all the NOAA 1:40,000 scale ICW strip charts from Norfolk to Key West but not necessarily full harbor detail (it does include many of the major inlets, allowing you to run offshore).

Unless you only boat a very small area, Wide+ or SuperWide+ are the most economical. Let me know if I can clarify any further for C-MAP users.
