Good to know I am sure I will have issues soon too, getting ready to mortage the house for a 7" and a 9"HDS gen 2 touch, I do have a question that You or someone else may be able to answer. I am planning on using a eithernet cable to connect the 2 units and am wondering if I can run both units off of 1 Structure scan transducer? also I currently have a 2d ducer on the transum and another built into My XI5 TM.
