Title: 2nd transducer
Post by: fivealive on February 04, 2016, 05:39:14 AM
Hello everyone. I have a 981c and i mounted the transducer on the back of the boat. the fact is, i would really like to have a 2nd transducer on the foot of my trolling motor for seeing down in deep water. Can you please tell me the right code for the trolling motor version of the transducer? And, in case everything i find is too expensive, can you please tell me if there is another cheaper model that will fit? side imaging is not as important for this kind of use. thanks a lot in advance

Your 981c SI came stock with the XHS 9 HDSI 160 T ...which is no longer made ... 

I don't think HB even made a trolling motor puck of this version SI ... Although they do offer a trolling motor adapter that might work if you could find another XHS 9 HDSI 160 T ...

I can't find a 50kHz/200kHz in a trolling motor puck ... But there is this transom mount ...

And the trolling motor adapter for XNT xducers ...

You might call HB to verify for sure ...

It should be the same 7pin "house shaped" connector used in your 981 ...

HB offers this option for connecting 2 xducers to 1 head unit ...
http://www.humminbird.com/Products/TS3/ (http://www.humminbird.com/Products/TS3/)

I urge you to contact HB to make sure this xducer option will work with your 981 SI ...because the XNT 9 DB 74 T is actually not listed in the "compatibility section" of that xducer on the HB website ...

I just completed a dual transducer install on the front of my boat. I am using a Podunk mount system I bought from him last year. I had a si ducer  that came with my 899.(I could have traded it in for the HD version). I added a DI ducer on top, installed the TS 3 switch. If you want I can send some pics when I get back from my trip this weekend.

hey guys,
so, as rnvinc said, my  981c SI came stock with the XHS 9 HDSI 160 T, which is no longer made. Well, I just found a used XHS 9 HDSI 180 T ... the price is great. Can anyone please tell me if it will work with my 981c SI?
Thanks a lot

The 455kHz imaging frequency will work ...

The 262kHz imaging frequency in the 981 will most likely not give very good results ...
