To Ihawkangler and other members - curious to know If you ever found an answer to this problem. I have the exact same FL 18 that you have. I bought mine 2 years ago. It has worked great in any depth of water. 2 weeks ago, I had the same problem. I was in 5 to 7 feet of water, and I could not see my tungsten jig. If I left the setting on normal with the interference dial set on 1, my screen would fill up with clutter (all the way around the circle). I changed it to low power and the clutter went away and I could see my bottom mark. But I could not see my jig on the way down or on the way up. My battery is registering 100% charged. I did the transducer test when I got home, that vexilar recommends, and it passed the test. Any help would be appreciated.
