The 1834 has no compromises, 10.4" screen, c-map chart and flawless radar. You wouldn't be making a mistake choosing Furuno. Only one thing you must be committed to learning the unit, not easy in the first couple of weeks and reading the manuals may give you a headache, At First. Once you are up to speed you won't change your mind. I suggest demo'ing the unit in a shop first. Call consumer marine (should be close to you) see if they have a unit on display to demo.
