Transom Mount Setup

[kd7633]

I a re-rigging my boat and will have two Helix 12 MSI G4Ns at the console. I am going to have a transom mount SI transducer and a "high speed" 2D transom mount transducer as well. Is it best to take these transducers to one unit using a Y cable or plug them in separately to each unit? I worry that if I plug them in separately I will have some 2D interference. I can share everything off the network so that isn't an issue.

Also, what is the model number of the preferred transom mount 2D transducer that people run for on plane/"high speed" scanning. Thanks for the input!

You will get cross-talk with two unit's transducers near each other.
The 9 M SIDB Y cable and both transducers connected to one unit is the best application.

The transom HW CHIRP transducer is the XNT 9 HW T.
Use this mount instead of the included plastic one if your boat does 35 mph+
