Summary: I had one on my 20ft Key West which I operated in the Lemon Bay area of the inland waterway on the SW Florida coast. This is a very shallow area and it's vital to stay within the deeper water. The included mapping and graphing was colored and detailed in a way that made it easy to stay in safe water. It took some time initially to learn my way around this device, but well worth the efort.
Summary: I have had my Garmin 440s for 4 years. Decided to update my maps for my boat/fishfinder. All I need is new marine maps. Why can't I just go onto the website and type in the name of my device and see what updates are available? After 20 minutes of hunting around, with no help, I decided to just click on one of the fancy software updates they were advertising. Got a big ad for all the fancy new things i can do with this, all of which I don't need.
