Hi All. I was just wondering if a 5 inch coil is worth purchasing? I own the quattro, and have the stock coil and the 8 inch coil for it. I have been told the 8 inch coil will be good enough in those high trash areas, and that the 5 inch coil will just collect dust sitting on my shelf from not using it that often. I was told that it would take a veryyyy long time to search a small area with it, and that between the 5 inch coil and the 8 inch one I'm really getting close to the point of diminshing benefits between coils. I was just wondering how others felt about this, and if anyone owns a 5 inch coil and how often they really use it? Thank's all. HH. Sincerely, Randy
