I've never used an ice specific transducer,
My last unit was a Lowrance Eagle Fish mark 320 I had it for over 10 years and never had a problem with it while ice or summer fishing. It's still running great. I bought the Helix because I just wanted to update. I haven't used it yet on open water but I can't wait.
