Still in need of the unit for the console but will study that one for a while and wait for the Lowrance side imaging announcement and cost.


I'd appreciate any GPS map card info anyone can provide. I'd like to get a card that gets me pretty accurate data for Barkley and KYL. My lowrance LEI fishing hot spot elite map in my handheld does not get me very close. With all the pre-loaded map options on the market, I will make a better console unit decision if I know what map to get. I hear Navionics mentioed as the brand to get but I don't know what year and model is required to get accurate and detailed maps. Some older GPS units only run the Navionics gold package but I'm not sure this is detailed enought. If my expectations are too high please let me know. thanks to all
I don't use the map chips (my Lowrance pre-loaded map does just fine for Laurel as I still use the sonar to "pinpoint spots" anyway) but from what little I've found out on the subject the older chips are the same as the newer (read more expensive ones) UNLESS they've charted them on the new release (example if the 2009 has a recent charting of the lakes you want it's best otherwise get the 2008 same thing less cost???)

Navionics is supposed to be the leader in the market on accurate and small contours, again from what little I know about this stuff

I've been "considering a nav map chip" for my Lowrance 520C " (even though I only fish Laurel with this pontoon) and IF I decide to breakdown and do it, I'll pass along whatever I find out....
