Question on how good the Garmin 840xs is compared to echo series Garmins?
I just ordered and received my 73DV with GT22 transducer with Lake Vu and also now have Bluechart G2. I now see that a few sellers are offering the 840 XS for $429 or less, no transducer. My question how well will this unit perform with the GT22 chirp transducer and would it be a good unit to add. I could use one as fish finder with chirp and the other full screen GPS. I appreciate any comments. The unit comes with preloaded Lake Vu and Blue chart G2. I would like to hear from any Garmin owners and any that own the 840.
