Its that time of the year again, "let's see what Cabelas has for their Black Friday specials". Myself I have been looking at the 106SV, but I notice the add only shows the Echomap 106 Ultra. How is this model different from the 106SV. I understand the difference in the 102 and 106 SV is enhanced mapping. Is this a Type O on their part. I just don't want to hurry in and buy something and find out it's not what I expected. I currently own a 93 SV and I was going to network them together. One other question, is the unit avaliable online, or can we only pick up in the store iperson on Black Friday. How do you all read that? Your thought folks. Thanks Papermouth Medic.
