I haven’t looked at one on a GPS except the downloadable iPhone apps so I was wondering if it shows the detail of marsh areas off the beating path of main bays and coastal regions??

Navionics with satellite overlay View attachment 73974 without overlay View attachment 73976 C-Map View attachment 73978 same basic area of Greens. I’m sure you can play with the settings for the C-Map and get more info than just bushes but I like the overlay.
That overlay is exactly what I was looking for. I just purchased a boat with a Lowrance Hook 4 GPS. I think this is a real inexpensive model and I am not sure if I could do the overlay with it. Does your unit prompt you in downloading the overlay? Is that just Google Earth?
Sorry for all the questions but this has got me pumped. Thanks

You don’t have to download anything. It’s a feature on the navionics chip. Not all units are compatible. With the overlay feature. If you get on the navionics site they have a list of units that are compatible with what feature.

I would recommend spending a little time cruising around it.
