What is your opinion on them? Thanks

Bill I have a Garmin 178C that uses bluecharts and I have always liked the way their charts looked and worked. This winter my wife bought me a Raymarine C70 with radar and with the Navionics Gold charts and though I have not used them on the water that much yet I find the Navionics to be a bit better. I have the two units side by side on the councel and find myself using the Raymarine more as the charts seem to have better detail and clarity.

I have a Lowrance fishfinder/ GPS plotter with the Navionics chip and love it. Makes navigating for dummies. I like it for locating humps and bumps. Cod fishing the north shore also shows ship/boat wrecks.

The Platium has even more detail...
