I bought an Ultrex with MSI w/I-Pilot Link Bluetooth [1368867]. My question is, what do you recommend as a fish finder for me to use w/o breaking the bank that I can use the full potential of this trolling motor. The main thing I would like to do is to find a structure within the range of the fish finder and command it to go there and spot lock it. Thanks for your input

I had a Helix 7 SI G3N that I really liked until I got the Helix Mega 10's.

I think that's the lowest priced HB that will let you do what you want. G4 now, probably. You might find a G3N somewhere if you try, but they are discontinued. Not sure about earlier models.

I think BPS and Cabela's have some Helix 7 G3N left for $699. About as cheap as you will find for the features you need. I am considering one myself to go with my Helix 10 DI, but am waiting for the fishing classic sale to see if they are cheaper then.
