Which sonar do you prefer?

Did you get the GT 20 or the GT 52 transducer?

I like to mount my transducer on a separate rod attached to the transom.  That makes it so I don't have to drill holes below the waterline, which I just don't like to do.

It also makes micro adjustments easier to do and makes the unit semi portable to take on vacations and mount on rental boats. Although I have a CV 4 that fills that purpose very well.

What is the boat it is going on? Aluminum or fiberglass?  Deep V"?  What angle of deadrise?

I'm interested in a electric trolling motor mount just to start with.  I have a striker 4 that I'm going to leave mounted.
