Queston on Garmin 73DV and 73CV with one of these trans ducers GT20 or GT22
I am confused on chirp with these two units, I have read articles and talked to Garmin support, but still confused. Does the 73DV give you chirp just in Down vu and is that a good thing. I was told the GT22 give chirp all the time plus clear vu, is that true and is that good. I think if buying one of these, I like to be able to use chirp and not use it. I am also looking at the 840xs and that comes with GT20 or can order without transducer. I appreciate any help on this issue.
