I am in need of advice on buying a Helix 9 SI/GPS. I currently have a helix 5 SI unit, but the side imaging is only 420-500 kHz and sub par. I have recently started fishing for bluegill/shellcrackers most of the time. The helix 5 SI the screen and detail just isn't capable of picking up on bluegill beds very well. So my question to ya'll is would I be happy with the Helix 9 SI unit? Not the helix 9 SI Mega, it is out of my price range.

Here is a link to the one I am looking at: https://www.hodgesmarine.com/Humminb...um409950-1.htm

My last question is according to the specs on this unit it will operate at 800 kHz in side imaging correct? Or will I have to buy a different transducer for 800kHz side imaging? Thanks in advance, I am new to the whole side imaging thing.
