I am looking at the Hummingbird Helix 7 si and have a couple of questions. From what I have seen am I right that you have to purchase a map of the Rez separately? Will the unit map the area on its own? If it will, does it map based on the area shown on the side image or on the down screen image? Anybody got one who recommends it?

Attachment 317094Attachment 317095Attachment 317096 Stuart, These images are from my Lowrance. The blue one is the standard Lowrance base map - not much detail. The middle one is the Navionics Ross Barnett map. The first one I created using Navionics Sonarchart Live. In my opinion a good map is worth the price. ANd one you make yourself is even better. This is all the same area. and don't be copying my waypoints
Thanks! I have NAVIONICS on my iPhone. Would you have any idea if I could download the phone map to a chip that would work on a Hummingbird.

I’m not sure but I doubt it. Navionics chips seem pretty secure to me.

Not sure about Lowrance, but with the HB 7 just pony up the extra $100 and buy the Lakemaster 4.0 Southeast States map card. It's has very good detail on the lakes I fish and even performed well on the Rez the one time I fished there. You have Autochart capabilities with the 7, but HB recommends the purchase of a Zero Line SD card, another $100. I read that a standard 32gb SD card would suffice for mapping (not 100% sure), but for the data conversion to existing charts is preferred to use the Zero Line card. You can autochart up to 8 hours just on the units memory, but that ain't mapping much of a lake the size of Barnett.
GET THE LAKE MASTER CARD YOU WILL BE GLAD
What Thump said, well worth it!!, good bout anywhere you go in the southeast!!
