788HD DI
« on: July 24, 2012, 10:02:47 AM »
If one has a 788DI on the dash and would like to add a second location in the aft, what cables would a person need other than a power chord at the 2nd mount, using only the one transducer?
thanks

If you are only using the one transducer you will also need a US3 Unit Switch.

So this switch is what I need to move the one head unit to the aft of the boat too view. There is only one head unit, two locations!

Yes, the US3 Unit Switch will allow two units, or unit locations, to use the same transducer.
