I have also wondered the same thing seems like the 1199 was made a lot sturdier than the Helix models from just looking at pictures. I would think the 1199 would be easier to take out and put back in the boat at the end of the day also. I have read where the Helix screen is much clearer than the 1199 also. This is a great question. I hope several will comment on this as I don't understand why or how Humminbird can now sell the Helix 10 for less than half of the price that the 1199 sold for. Just wondering if the older legion models will be working when the helix's has bit the dust.
