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??
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?
Thank you!!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.
I actually went to the Navionics web site and downloaded the app for my phone in which it let me go in and change to the satellite image.The Hook runs no charts that have any photos and the software running is insufficient to control map layers on more detailed charts.
