My vexilar has never failed me. Had it for many years. Anything with an lcd will freeze up in cold temps, although they have gotten much better. Never had a problem with the vexilar, I have the genz pack
Buy it once and get a marcum so you can drive all the vex guy's nuts when you fish next to them , I have a cheaper marcum but would like to upgrade to a lx5 or the new digital lx7 these unit are amazing and the best part is there made right here in the USA , and you will be able to talk to a live person for help if you need it.
