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
To connect 2 xducers to 1 head unit you would need the HB TS3 Switch (which supposedly has been discontinued) ...

HB website allows adding the HB TS3 Switch to the cart but you should call to make sure (because it was reported discontinued) ...
Some dealers may carry the HB TS3 Switch ...

The picture on the HB website is misleading ... The HB TS3 Switch is basically a Y cable with a 12v toggled relay at the "Y" ... The Pic only shows the included 12v selectable toggle ... It doesn't show the Y cable ...

No help here, just reminded me of the old days with my Super Sixty and the toggle switch going back and forth from bilge to tm. Had the unit on the port side bow so as to read it underway, toggle up front. Venture bass boat. Long time ago.
