I think you will be fine with The X125. I still use a 15 year old X67c. Even though I am upgrading electronics for the boat, I will continue to use the X67c for ice fishing, along with my iPhone with Navionics for mapping. As long as it shows depth, fish, jig and bottom composition, I can't see what else you would need, except a map/plotter which you can download to any smartphone. A new Vex is essentially the same old vex (mechanical flasher) with a few bells and whistles like zoom. I'd rather have a graph.
