I have two HDS units on big boats, and a 998c SI on my walleye boat. I am going to replace the Humminbird this year. Two years ago I put a GPSMAP 7610xvs on the lake superior boat and I love the Quickdraw contour on the fly feature. I'm thinking of a Helix 9 chirp mega or GPSMAP 7607xvs to replace the 998. Anyone use Autochart? Anyone using a 360 or panoptix down transducer?
