Direct From Navionics...
Hi Brad,I have been a Navionics employee for 6 years. I just happened to stumble upon your blog, so I figured I would shed as much light as I can on the subject. Both the Garmin & Raymarine units have been selling like hotcakes because they are both good products. I honestly don't know all of the technical features of these units so I can't help you there.I can help you with the cartography. Garmin has their G2 maps, which have some nice flashy features, almost-comparable to our Platinum charts. Unfortunately, our Platinum charts do not work with the C-80; if they did there would have been no comparison.You mentioned that the magazines tend to favor Navionics charts. That is not just because we pay them; in fact, most comparison articles are very unbiased and if anyone would have the most money to pay them off, it would be Garmin. The reason they favor us is because when anyone does enough research, they find that we go the extra mile to make sure our content is the best available. The Navionics Gold+ charts which work in the C-80 unit have 3 major differences from Garmin cartography:1. Tride-And-True Cartography: Navionics charts come directly from the government NOAA charts. Garmin uses a Russian database called Transas, which goes through many hands before it gets to them. I am not going to say that Garmin charts are very innacurate, but since we get our data directly from the source, there is far less chance of error in the chart digitization process. The result: The most reliable data available.2. Seamlessness: All electronics charts are made up of many small scanned "paper-charts" that are put together like a puzzle. Navionics is the only company that "pastes together" these charts and connects all the contour lines and navaids from one chart to the next so that when you cruise along, you will always get smooth, easy to read detail. Other electronic charts are not fully seamless, leaving gaps in detail and broken depth contours, making it more confusing to read.3. Clarity: We have developed a very complex system which we call "Intelligent Clarity" in our charts. To explain: The competitions' charts leave every spot sounding, navaid and contour line in every zoom level, so when you zoom out, the picture gets more & more cluttered as the detail pushes closer & closer together. With Navionics, we take out some of the spot sounding and lesser important Navaid detail so that you when you zoom out to get a better view of the area, you can still read all of the detail clearly. When you zoom back in, all of your detail comes back.Aside from all that, our charts are upgradeable & tradeable. Your Navionics chart always has value when you want to get updated data. Please see the following link for more on our trade-in program: http://www.navionics.com/TradeInProgram.asp.There are some very exciting things coming up with our charting, but I can't really say anything right now. All I can say is that in January, our chart coverages will be expanding without raising price, giving even greater value to Navionics charts. Stay tuned to our website, www.navionics.com, for details.I hope I have helped you, rather than confuse the issue further! If you have any question, please feel free to contact us at 1-800-848-5896.
