For those of you that have the new brushless motors i.e. force or ghost do you see any appreciable difference in R.I. on your graphs. While my ultrex is not horrible I have always experinced some interferance while running the trolling motor.I've already FYI been down the road of all the normal fixes and yes I can turn noise reject up high and eliminate even more but this also reduces the abilty to pick up some returns. Curious as my ultrex is a gen 1 and has a lot of hours and will probaly need replacement in the not too futture. Scott
