So at first I absolutly hated my 80# Xi5 that was on my boat I bought used. After learning to use it a bit and the very complicated commands that I still don't have memorized I am begining to see the benifits. The anchor function is an amazing feature to have as well as the one touch Course setting option. That basically allows you to point the boat in the direction you want to go , press the button and off you go. you can stop at anytime press the button and go again and it will actually put you back on the same line. The TM is integrated with my electronics and be used from my lowrance very easily. I'm hoping to find more video tutorials to help me get better. I wish it was 36 volt though.
