Side imaging has been great for me. I can mark all the cribs in my local lake mark structure AI want to go back and fish, mark pods of fish, etc etc. I even put my ice shack right between 2 of the cribs I marked using my side imaging unit If you are able to get it, get it. You won’t regret it. I have seen both and I think you will be happy with either Lowrance or Humminbird.
