Navigation system mapping chip?

[Spots and Dots]

I got a Simrad Go9 on my skiff.

Anybody know some good mapping chip systems for the Texas coast. Looking for something to show me safe areas to run when I'm out of my home water.

The hot spots maps they have at academy now are offered on a digital card for your plotter... I use Navionics Hot Spots for my lowrance.

What's the difference in that and a avionics Platimum plus? Looks like they cost the same
