Helix 10 SI/ which 2D transducer

[Sewerdude]

Ive got a Helix 10 SI Mega G2N that I have a Y harness installed which is split to a XNT 9 20 high speed sonar transducer, thats only 200/83 khz. I had it on the transom when I was running a Helix 7 which I replaced with the Mega 10.
My question is, is there a better 2D transducer that that would allow me to benefit from the chirp function and the other features that the 10 SI has to offer? Something that would still have 200/83khz and up?
Would I be able to use this transducer with a Y harness? Humminbird XNT-9-HW-T

The unit CHIRPs the 9 20 83/200 kHz piezo if you have CHIRP turned on. It is not Low-Q CHIRP though like the Dual Spectrum piezo.

The HW (high wide CHIRP) piezo is tuned to 140-240 kHz and won't work with 83 kHz. Does somewhat OK with the 200 kHz single frequency and CHIRP but does not give the unit the capability to use the whole CHIRP range of HW, you would still have 175-225 kHz CHIRP.
You do not have a setting to have HW with Side Imaging.

Bottom line is if you want Dual Frequency, the HW is not for you.

Thanks Wayne,
Is there any other option for a 2D sonar transducer that would work well with the Helix 10 Mega? Or am I stuck using the XNT 9 20?

You can check what AIRMAR has for a dual beam CHIRP rated transducer.

Ironically, I called them yesterday with pretty much the same question.I wanted something better if all possible than the XNT 9 20. I asked on here and Wayne agreed that you cant use the XNT 9 HWT with a Y harness with my Mega 10SI. But, the lady on the phone from Hummingbird did say that if I had a G3N Mega that it would work, but not with a G2N model. Im not educated enough to know the difference between the G2N and G3N versions. So, Im just sticking with XNT 9 20 and a Y on my 10 SI Mega.
