Will it improve anything on my Helix 10's to go from the 1.9 to the 2.1 update? If Im reading things correctly it looks like its all about getting the 360 better which I dont have. I like the way my Humminbirds are working except in shallow, soft bottom areas where it looses bottom. I read things on here where some guys update and then they have issues so I dont want to do it unless it improves that one issue shallow water problem that I have. Thanks!
