How has the new base map update for the helix treated you? I went to download yesterday and realized it was a 7.9GB update and I only had a 4gb sd card...in the process of finding a 16gb.  I am very interested to see how many "new contours" this will unlock.  Humminbird is stating the download includes contours of over 10,000 lakes.  You can go online and check out all of the lakes included.  Seems like a pretty big step for Humminbird to offer this for free and considering its 7.9GB its quite the update, will this effect the sales of map cards? Once I get the SD card I will post some before and after pictures of a lake around me that I seen will be on the update.

 

sorry for the delay here are some before and after pictures of Canadian side lake st Clair (Mitchell's Bay Area) was just a blue blob before the update; after the update you can see some added bouys, depths, etc. Not bad for a free update!  Currently trying to upload pics...
