Love older Lowrance units, had a 127c on the front of my boat for years and sold it so I could go Humminbird all the way to go with my TM so all would work together. However I still love that old 127 and it never lied to me in spring I always knew when the crappie had come in by the way they showed on my screen on that unit. Now with the new Down scan on front is better in many ways, but have not learned the regular sonar for this one yet.Have to say I do love the side and down scan units and thought I may have messed up going with Humminbird, but sticking to the not going Lowrance since they sold the company! When they got rid of the best help a fisherman had at that company and with all the complaints I saw, not going there any time soon!Plus I hear LakeMaster will finally chart HD on lower end on Toledo Bend which is where I fish will then allow me to set a count our for it to follow with out me having to steer it, looking forward to that one! My equipment is ready and only need the HD map to make it great! Can save a track now and have it follow that any time I want, but want to pick a depth contour for it to follow.Skip
