From what i read you get color and a bit larger scren with the Garmin but
No GPS .
The Lowrance is gray scale,gps included and a more common transducer.
I'd have to go with the Lowrance for the GPS!

I think I'm reading the correct ad for the Lowrance you referenced, not sure because you posted the Garmin ad Twice.
