I would not if that is your only reason to get a Humminbird, but have you checked out some of their latest creations, and their customer service is way better than Lowrance.
totally agree. I had three Helix units when I bought my Ultrex, so I boiught the Link version. Since then, I've changed boats and the new boat had Lowrance. I have sold two of the Helix units and kept one. I NEVER use the contour follow and only played with the i-track stuff once to say I did. The saving of spots is useful, but even then, only slightly.
My vote is save your money.
