I’ve only been able to use this model a few times so far, but so far so good. Navigating through the menu is super fast and easier to use than my lms 520c. The sirius satellite antenna for weather is nice for the price.  Great detail on the graph.  I’d say it’s the same as the 520c just with different colors. Everything considered, a good upgrade

This GPS/Fishfinder is sweet!!! The screen is so bright and readable!! It’s easily visible in the brightest Florida sun. The screen has multiple layout modes and is very user friendly. The nautical insight is sweet too. I use it mainly in the Gulf of Mexico and wouldn’t even consider buying a unit without Insight. Highly recommended.

I bought this for my sailboat so the fishfinder is not used much but the chart plotter with a Navionics chip is great! I have it tied in with the autopilot (easy job) and the boat follows my tracks! The display is awesome.
