navionics hotmaps

How are the maps of the flowage on the navionics hotmaps chips?

Pretty decent. I can drive around in the dark there with one and not hit anything..except maybe a bog.

Thanks I am looking to buy a chip. Some like lakemaster better but I would need two or three to cover what navionics will cover. I mainly want it to navigate. I fish the flowage one week a year. I spend most of my time in MN. and some in SD.

You should be good with that one then. My chip is a few years old and I have no problems buzzing around out there.

That's the one I use out here on the Chip and it's pretty good. The Lakemaster is a little more in depth but harder to read.
