I have an older Hummingbird 899 ci HD SI combo + GPS sonar with Dual SD card slots, that I don't really know how to operate very well. I decided it is time to buy a mapping contour SD card. Not sure what to get or where the best place is to get it from. Thinking Lakemaster because have Hummingbird sonar, but maybe other brands are better (navionics?). States compatible with Lakemaster Autochart and Navionics cold/Hot maps. I think I need South West US card to cover Utah lakes and Lake Powell?
I want to be able to adjust the lake level on my sonar so the contours are correct, but don't know if that is possible with my unit or not, or if one brand of card is better than the other. Lost my instruction book so looking on line and more confused than ever. I am an old flip phone guy, and this is all confusing to me.
At one time the 899 Hummingbird was top of the line, but now it is probably way outdated.
Anyone out there have a 899 that can give me some suggestions. Where is the best place to purchase a card? and what card do I need? Can I adjust the lake level on my sonar? and how do I do it?
