I started with the 93SV, then upgraded to the 126SV, and now I’m running the 1643. I’ve also spent a lot of time fishing with a buddy who has the 1022. From my experience, if you can afford the 12-inch unit, go ahead and get it. You’ll eventually outgrow the 10-inch and wish you had the larger screen—the extra screen real estate makes it a little nicer on the water.
