Yes much more detail then the gold card. The gold card is really a navigational card, not a fishing card.
If you have to buy new and can't find used. Make sure to buy the updates card as it is $110 at Radioworld and you can activate it with your fish n chip card. Once activated you can download any areas you want and have the latest soncharts (fish n chip) data. You will get the exact same data you see on your mobile app and what you see on the web app at
www.navionics.com. So for $110 it will be hard to find a cheaper used platinum plus. I know I'm giving unsoliciated advice and I hope it doesn't rub you the wrong way. It's as much for others reading this as you. Hope that is ok.
