Topic: Is there any way to id transducer difference ...180... vs ...160...

Is there any way to tell the difference between XHS 9 HDSI 180 T vs XHS 9 SI 160 T?
Either physically when looking at just the transducer?
Or when hooked up to 997c with some type of menu info?

Hi,
I have both transducer models and understand your problem. I have not found any markings engraved in them that tell which is which. The XHS 9 SI 160 T (the "old" model) is a bit heavier because there are two, big, circular downward elements in it, the XHS 9 HDSI 180 T has only one. But I don't know the exact weights. There is no unambiguous menu info or feedback from the system that tells the type of connected transducer. You have to test on water with different transducer select settings (if available in your unit). The default in the 997 is the XHS 9 HDSI 180 T which means all channels will work if you use that transducer. If you connect a XNT 9 SI 160 T to a 997 with the default transducer select setting you will get no (or very weak) sidescan image at the 800 kHz setting and no (or weak) downward 83 kHz image. This is because the XNT 9 SI 160 T uses 200 and 50 kHz in the downward channels, while the XNT 9 HDSI 180 T has 200 and 83 kHz.

There should be a printed label on the transducer cable within the first few feet of the connector.  If this is an older transducer this labeling will be printed in either white or yellow on the cable itself and was not always easy to read.  Newer transducers have a printed label that wraps around the cable and has a bar code on it.

   Forgive my ignorance and lack of attention...! I checked six of my transducers and found the code on the cable on all of them. I just never thought about searching for codes on the cables.

Don’t feel too bad there Rickard, there are more than a few cables out there that do not have any markings on them…

Greg, your info was spot on, thanks.

After cleaning a bit of grime off the cable with mild soap and water, yellow text was there about 10" down from the connector. Confirmed it's the ...180... transducer.

Anxiously awaiting to get through the northeast winter so I can hit the water and put the new2me 997c into action.
