Not even in fishing or boating magazines.I guess there is just not many people using it because it is not a very user friendly function. I also wondered from time to time, why I did not see or hear anyone discussing it. When I first read about this quite some time ago, it sounded really cool but I did not know how complicated it was to use the feature or how well it might work. If I had seen your original post, (which by coincidence was only a few days ago) it would have shed some light on my curiosity. Going hungry, Thank you very much for the explanation. Sent from my E6782 using Lake Ontario United mobile app Edited Apby goin hungry I know it seems like a lot and can be frustrating that you paid a pretty penny for technology that isn't quite there yet, but after you do update your maps with your logs it's worth it, and I know that the technology will only get better - like the way you're already able to update your maps instantly if you have WiFi capability through certain phones and sonars. Here is a link to a post that I recently did on the more advanced info that you need to know to make use of it on Humminbird, but I'm sure some of it carries over to other models too: I can see why too - the instructions you get from navionics, and what's available on the web, really don't show all that you need to know and do to use the program and your sonar to it's fullest potential with the program and sonar that I have. I was surprised myself to see that some areas that I know are heavily fished by serious guys doesn't have more information in their maps, but I think many guys don't take the time to record their loss and update their maps for the community. Then the next time you go out you will have all accurate information. Basically, those maps will get you started, but then you need to record and upload your specific sonar logs. I have navionics+ and also update to the community function every trip.
