I buddy reached out to ask my opinion on the Zoom feature on regular 2-D sonar. I told him to forget it. It may be handy from time to time but 9 times out of 10 you just don't need it. I also mentioned that it is good to learn more about it and how to use it, so when the time comes you are not messing around trying to zoom or split zoom instead of catching fish. #ittoutdoors #WalleyePodcast #Humminbird #WalleyeFishing
