I can hit about 3.0 with it. My tracker is just the 175 txw. kinda have to be careful with the remote, if i hit prop on and it is on full it will about toss me out of the boat. I cant wait to get it linked up to my Lowrances, I still got to get rid of my bird on the front and buy a HDS touch, Any suggestions? I have a HDS 7 i plan on moving to the bow and i want to get one for the back, i kinda feel the hds7 touch will be to small at the console to run the side scan.
