Re: GPS - Standard Horizon CP 180i
Now that we are on the subject of charts, you may want to explore your options. 3D is now available form Max Sea, I suspect others will follow suit soon. If you buy a C map, they then want to sell you the latest version that may or may not have upgrades. From my understanding, all these electronic charts are based on one source, NOAA. They then make enhancements, add port date, bridge info, etc.
Take a look at Max Sea, then look at C Mpa, via their web sites and you will see what I am referring too.
I have been holding off on buying a 10 inch GPS, and 10 Radar (want separate units) until I can figure who is going to have the best contour data. C Map is fine for navigation, but I really want to see the bottom contours. The Max Sea looks impressive, but it is only available for PC.
I think I have the facts right, if not, let me know. Thanks
