Back in the late 1970s and early 1980s, I vaguely remember some gizmos being sold as supposed radar detector boosters. They were clear acrylic about the size of a halved golf ball that you were supposed to stick over the horn "lens" of a Fuzzbuster to boost performance. They had a weird red and white spiral pattern sticker in them just for looks. Obviously, they didn't do shyte, but I remember them selling like hotcakes in the CB and auto accessory shops.
Anyone else remember those? Jimbonzz? This would be an interesting addition to the Radar Detector Museum if we could find one.
