Page 3: About Your Detector
ABOUT YOUR DETECTOR Your CZ-20 QuickSilver is truly an all-purpose metal detector engineered for land, beach, salt and fresh-water treasure hunters. Here are some important built-in features: 1. Leakproof: Submersible to 250 feet, headphones and all. 2. 3-Tone Target I.D.: A low tone for iron, a mid-tone for pull tabs, foil and most gold rings, and a high tone for U.S.
