Depth Finder X125

I was watching Bassmasters last week and they were fishing drop shoots. they could actually see their line in the water on the depth finder. I have a Lowrance x125. Would that be senative enough to show this up? If so, has anybody had experience with the settings?

Yes, but that wasnt their line you saw it was the sinker,worm and swivel going down

play around withthe sensitivty and the gray scale and you'll figure it out.
