I am Looking at a new Ranger that has that system. My question is do you have just 1 x-ducer?  I am wondering how you can have 2 x-ducer's on the same data wire as the front & the back of the boat will not always be at the same depth. It also has 1 GPS antenna so if you mark a waypoint on your front unit & the antenna is on the back you are at least a boat length off. I must be missing something can someone that has the system how it works. Thank You

The transducers are not networkable thru the Lowrancenet.  Each unit will have to have it's own transducer.  That is why the network connection and the transducer connection on the back of the unit are seperate.  To get the best accuracy have the gps antenna mounted as close to where the transducer is located, if it is a boat length away, like you said, you already have that as a margin of error.  That is why I have my setup so each unit has it's own gps antenna mounted near the trasducers at the back and on the trolling motor.
