Cane Pole and Earl, Thanks for the sensitivity and colorline readings. I am still a little confused ,as the deepest water in the lake is 18'. Do the sensitivity readings relate to how much or how little. I am used to -3 being less than say a 30 or 40. I tried these 'settings and still had some clutter in the water column. Should I use less sensitivity because the water is not very deep. By the way I am using fish icons. Should I be using fish arches? I am getting better using the GPS and hope I get enough use out of it to justify the additional cost. I love this forum and the guys that are willing to share their knowledge and help a fellow out. After reading many post I know that you two are very knowledgable and willing to share that knowledge. Thanks again
