Humminbird Auto Chart
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.
