Humminbird Auto Chart

[silver]

I am thinking of picking up a Humminbird with Autochart and I have a question for the guys with experience. Do you have to use the Humminbird SD card or can you use any SD card?
I would like to fish the North Sask river since it is close, places to launch a boat are limited, and if you can launch, dodgeing sand bars could be tricky. Right now the river is high and if a guy could find an easier way over the sand bars it would make it easier for when the water goes down.
Right now the Humminbird card is about $100 and I would like to keep it for most of my use. I wouldn't mind picking up another SD card to use as my high water card.

I have a Lexar SD card and it works just fine. I didn't even know humminbird made their own SD card.

You can record sonar to any SD card but you need the zeroline card to use autochart live.

The Autochart zerolines card I use on my Autochart Live unit will record a crazy amount of data - I have recorded a crazy amount of structure and I'm pretty sure there lot's of space left.

You probably don't need a sperate card, and if you do, you can always copy the data by region (or date) over to the other card.

Sorry to highjack a bit here, but how can a guy re-write an area? I ask because while running on plane, my unit recorded a bunch of crappy data. I then went back over it slowly, but it didn't change my map. Anybody know how to overwrite data on the card?

That's strange - if you drive back over an area the map should over write the data (and inaccurate map). Mine does - not sure why yours would not.

I have only noticed it once. Glad too hear it should work good

Eventually it does crowd out the bad data. You could also delete the file with the bad data if you can find it. I downloaded my autochart files to my laptop and there were hundreds of them.
