OK, I know I have seen on the forum somewhere the Humminbird model number for a 2D high speed transom mount transducer. After 30 minutes of searching and reading posts, I give up. Would someone be kind enough to give the model number I need. It will be used with an 1197c SI, I do not want a quadbeam, and I know I need a Y cable.
For some reason I am search impaired today.
Thanks,
ED
