I bought a used Helix 9 DI G1 off of ebay to replace a 859 I had on the bow of my boat. The ebay ad said that it came with a new transducer. When I unpacked my purchase the new transducer was a XM9 MDI T. I went to the HB website and found that the XM9 transducer is for a Helix Chirp Mega DI head unit and the transducer that originally used with the G1 and the 859 head units was a XNT 9 DI T. I plugged the XM9 transducer into the G1 head unit and power it up on my bench. The head unit appeared to recognize the transducer (temp and connected transducer freq.).
Now the questions.
Should I install the new XM9 transducer on my trolling motor, and replace the XNT transducer that is currently there.
Will the XM9 transducer function properly with my new to me G1 head unit.
Or do I just plug my existing XNT from my 859 into my Helix 9 G1 and go blissfully down the road.
