I want a Garmin Force, but not sure on electronics

[chrisntab]

I want to buy Garmin Force trolling motor, but not sure on electronics. I want a brushless motor and need the 57" length, so only one option on market currently. We do a lot of trolling, creating routes, follow contours with competitors, products. I was told I would need Garmin electronics to do so. How is SI & DI in compared to Mega or Mega+ of the Garmin. I have experience with both of these and 3D,3n1, Totalscan of other brand, just zero experience with Garmin. I have no need in livescope. I could run both like I have read many others do.

What unit 10-12", transducer combination would you recommend to get awesome DI & Si?

Thanks in advanced

Get livescope, it's like real time down imagining in front of you and has so many other advantages livescope is as clear as mega DI and you don't have to move to see what your looking at
