I had my new boat rigged with Helix 10's and decided to save a few bucks and go through the chart select process to purchase mapping of Sakakawea for each of the units since I pretty much fish Sakakawea exclusively and the Helix units will not share the mapping information across the network. What I found, is although it's supposedly only 8 gb worth of data, it required a 32 gb card which is outlined on the website. My first attempt to download onto a 10 or 12 gb card failed as the card was too small apparently. Second attempt worked however it took like 2 hours to download the map onto the SD card via my home laptop. The lakes he mentions are in his words "big" at 200 megabytes worth of data, not gigabytes. After going through the process I'd be concerned about some interruption in connectivity or otherwise knowing how long it took mine to simply download directly to a card.As far as storage, I know the units themselves have a fair amount of built in storage as they will store around 10 or 12 hours of auto-chart live data internally without a card, I presume that's what he did in the video. Not sure if you can force it to write the map to your zero line map card as installed, or if f you would need a blank SD card, that might be worth a call to the humminbird support line. I know way points will store to a lake master card as I moved mine and was presently surprised when all of my points showed up. I assumed they stayed with the unit unless you were to download them to a separate card</blockquote>

Verification: What is the most common fish caught on this site?
