I bought the G3 card for my 93SV Plus. Used it at Port Isabel and Mansfield. The imagery along the ship channel is hi-res, great stuff, a half mile or so off the ship channel, it's garbage and useless for the rest of the area north towards Mansfield. I'm pretty disappointed considering the cost of the card. I also found the contours to be grossly inaccurate from Mansfield to SPI.

The Standard Mapping won't reach that far west for Baffin.
The G3 vision BlueChart will have it. I will suggest taking a look at someone else's unit with the Satellite imagery on it for that area.. you may or may not want it after you look at it. Some areas are great, other areas, meh.. not so much.

If you are fishing any of the Galveston, Trinity, East Bay, West Bay, Chocolate Bay, Christmas Bay areas without Reef Recon you are going backwards. It is a no brainer and worth 5 times what you will pay for it. You could charter a lifetime of guided trips and not get this information.
Of the two above..
if you're going to fish in the marshes a ton.. I 've heard that the Standard Mapping is better.
If you're going to fish the main bays more then you'll likely use the Garmin G3 Vision card which should give you both countour maps and satellite imagery
