Is this a 7 pin transducer
Charilaos D.  27 December, 2022
hi there are two versions of TM185M in your store. The Navico XSONIC TM185M (costs 736.15) and Airmar TM185 Medium Chirp (costs 984). Whats the differencies between these two apart the mix and match cable?
John G.  05 January, 2023
Navico xsonic 9pin version is comes with lowrance/simrad plug. So it will only works with this brands. Other $984 priced version is mix n match plug, it comes with compatible 3ft adaptor cable (mix n match) if you ever change your fishfinder to another brand, no need to change your transducer, you only change your 3ft adaptor cable.

The GO9 is not rated to run a 1kw transducer so it will not perform exactly as it should.

The Elite FS series cannot power a 1kw transducer so this will not be compatible.

Yes, this works on a Live unit, and this is the right cable.

I am not confident this will operate trouble free for you.  We have seen some incompatibility issues among some Lowrance displays and some of Airmars more specialized ducers like this.  Not enought data to pinpoint specific units or ducers though.  I recommend speaker to airmar and Lowrance directly to ensure you'll get what you want. I can confidently answer regarding the technology.  A 1kw chirp medium freq ducer like this is your best bet for fishing deeper in the water column, and this style ducer will work great for your boat. 

By James Maier on 09 July, 2020

Yes, it will.

The NSS Evo2 uses Simrad's Blue transducer plug. You would order the Mix N match version of the TM185 and get your free adapter listed under it "Lowrance & Simrad CHIRP Blue 7 Pin Mix N Match Cable"
