There seems to be a lot of confusion on the Humminbird definitions and compatibility sometimes. I figured I’d start a ‘catch-all’ thread where people could go to find the most frequently asked questions. I will try to edit this first post to keep this up to date and information at the top.
What do the abbreviations stand for?
#### = model series
c = color display
i = internal GPS receiver
DI = Down Imaging
SI = Side Imaging
NVB = Navionics Value Bundle
Combo = Sonar and GPS features are on this product
Chartplotter = GPS features are on this product, Sonar is Not
CHO = “Control Head Only” no transducer included, even though sonar features are part of the model
HD 700 Series = LED backlit, Ethernet compatible with a $30 adapter cable
Non-HD 700 series = NOT LED backlit, NOT ethernet compatible
HD 800/900 Series = LED backlit, Ethernet port on the back of the unit
Non-HD 800/900 Series = NOT LED backlit, Ethernet port on the back of the unit
Non-HD 1100 Series = There are no ‘non-HD’ units in the 1100 series, therefore no 1100 series have HD in their model name
As I think of more items, I’ll try to add to the list. If you have questions, post here or other places and I’ll try to keep adding to this.
Hope it helps clear up some confusion for some users.
