Title: 2 Transducers With 1198 Units
Post by: calli1 on May 20, 2012, 10:27:48 AM: Ok folks...I started out with 2 transducers with my 1198. Then I had a problem with either the older 2 d transducer storting out or my "y" cable. I know basically the only good reason ( I think ) on running 2 transducers is running at a higher speed to tell water depth ? Correct ? Is there any other reasons and how do many of you run your...with 2 transducers or just the one that comes with the unit. I will post and wait for your replys. Thanks again for this great website. What GREAT Resource tool for us Side Image folks.

I think the main reason for two transducers is for high speed boats.
The transom sometimes lifts out of the water so high on these, that the standard
transducer is no longer submerged, and won't work properly.

There is another reason for having two transducers, which I am now contemplating.
You could get a 2-D transducer with more detail and coverage than the standard HB transducer.
An Airmar, for instance.

The side-imaging, down-imaging will still come from the standard HB transducer, while
the 2-D can be from another transducer.
All the units get their depth from the 2-D transducer.

The inside-the-hull transducer you need is the XP-9-20.

Post by: calli1 on May 22, 2012, 03:00:11 PM: Greg...I'm going with a outside mount on my transom and the Humminbird Tech lady said the XNT - 9 - 20 . Is she right...hope so....the trans is on order now. I have a Aluminum boat and do not trust the through the hull transducer.

Post by: Humminbird_Greg on May 22, 2012, 04:01:34 PM: calli1, did not know or remember that you had an aluminum boat so the outside XNT-9-20 transducer would be the correct one.
