Title: Does the transducer was build to be used at high speed or not?
Post by: Beaulieu80 on July 17, 2014, 01:22:06 PM

I'm starting to see many post from users and video from Humminbird that we should use the small transducer for speed reading?

my transducer is: XNT-9-SI-180-T

does my 798 default transducer is build for that matter too? Or I paid too much for nothing?

Many Side Imaging unit owners use a second transducer for 2D sonar readings for one of two reasons:
1. The Side Imaging transducer they have cannot be mounted in a location on the boat that allows for unblocked Si sonar and high-speed water depth readings.  They also may not want to deal with having to possibly move the transducer multiple times (more holes in the boat) to find that mounting location.
2. They want to mount their Side Imaging transducers in a more protected location on the boat so that it does not get damaged from winterbourne debris, rocks or stumps and logs.

Yes, the XNT-9-Si-180-T Compact Side imaging (CSi) transducer can be used for high-speed water depth readings but it is usually easier to mount a smaller sized transducer on the transom of a boat (or one that can be mounted inside-the-hull) than the larger CSi transducer.  This is even truer with the even larger HDSi transducers.

Can I use my smaller transduer of my 565 unit? is so, why cable I should use to allow me doing that to work with my SI and 2d  view on my 798 unit?

thanks

Yes you can Beaulieu80.  The 565 uses an XNT-9-20-T DualBeam transducer which is a basic 200/83kHz 2D transducer.  This is one of the transducers that we would recommend as a 2D transducer for this.  I am guessing here that you have an aluminum boat, correct?

You will need the AS-Si-DB-Y cable to connect both transducers to your 798 unit.  the 2D sonar will always come from the 2D transducer (your XNT-9-20-T transducer in this case).
