My Boat had two H -Bird units .. A tree limb broke the screen of one ... I do not feel safe on the water moving the only sonar head from one mount to the other... Looking at the switch for two Transducers it does not show the connections --- this makes me believe that it is an Ethernet connection -- my Boat is 14 ft with stick steering and very little room ... Is there a simple connector from that $100 switch to connect the unit to the two Transducers or buy another used head from E-Bay
