His comes with a trolling motor transducer but it could be used on the transom if you could mount a L bracket to the transom and then mount the transducer to the bracket. I changed to a Humminbird Onyx10. This might have been used on the boat a total of three weeks. The item "Lowrance HDS-7 Gen2 Lake Insight USA Fishfinder" is in sale since Sunday, May 01, 2016.
