I was in about 20ft of water and I think it was picking up a horz range of about 6-8 feet. It was overcast with stained water. The light does not help that much during the day but works great at night, I dropped it over the side of the houseboat at night and checked it out. This makes me think that when the sun comes out and the water is halfway clear that this thing will work much better. My ticker was pumping when I saw those big sows!
It let me know that I was on the right spot even if they didn't bite. Used it for about 30 minutes and saw about 10 big fish. No problem with the details on the fish, you could even see the markings on the fish.
