i made a portable transducer mount that i can hang on the side of my boat and as long as your setting still over structure or even suspended fish you can see everything thats going on below.In perfect situations, with the scroll speed as high as it will go, sometimes you'll see a streak come up and bite ya. it helped me to understand kinda what was what and what was where and when. You can move it further back on your boat when slow trollin and really see whats happening. The key is keeping your lure in the cone and scroll speed on high.
