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.

    Anyone at all own the Garmin 840xs and willing to give some pros and cons, or what other combo unit would you recommend under $500. I would use it probably just as GPS unit with full screen.

    I just bought the 840 at that good price. Assume these will be discontinued by Garmin, hence the price.Haven't installed it yet, but I am curious also.

    I like my Garmin 50DV, so I decided to go with the 73DV, have been working with it hooked up to a battery, like the ease and what I can do, cant wait to try out the chirp in March. I also decided that no new boat for me the one I have is great, so I ordered the 840 xs no transducer since I can use my GT22 for either unit. I will enjoy using this unit as well in March.

    Dockside let me know when you install your unit and the pros and cons. I updated the sd card with the latest update for the unit and will install when I get on Thurs.

    I talked to Garmin today and when you register you new 840xs they will update you charts for free, they do this for the first year. After that year their is a charge. I will do that as well. I have to check how to do that, I think you do with SD card but not sure.
