I have a hummer 997si on the console connected to a 797 hummer on the front. Way points are shared between the two. great for marking on the console and coming back on the troller and its already marked on the from hummer waiting for you. The side imaging is sick and the down scan is awsome. And you can update your hummers so your unit always has the latest and greatest.
I think everybody should get a couple of hummers
there the best
