{"product_id":"fisher-cz21-underwater-multi-frequency-metal-detector","title":"Fisher CZ21 Underwater Multi-Frequency Metal Detector","description":"\u003ch5\u003eThe CZ-21 QuickSilver by Fisher® Research Labs is a trusted and reliable metal detector, known for its robust design and exceptional performance in both land and underwater treasure hunting. Built to withstand the toughest conditions, the CZ-21 is submersible up to 250 feet, making it ideal for detecting valuable metals on beaches, in saltwater, and freshwater environments. \u003c\/h5\u003e\n\u003ch5\u003eFeaturing a 3-Tone Target-ID system, the CZ-21 offers clear audio distinctions for different types of metals: a low tone for iron, a mid-tone for pull tabs, foil, and most gold rings, and a high tone for U.S. coins, silver rings, and some gold rings. This allows users to easily identify and differentiate between various metal types without even looking at the display. \u003c\/h5\u003e\n\u003ch5\u003eThe detector utilizes patented Fourier domain signal analysis with two deep-seeking, ground-compensating VLF signals operating at 5 KHz and 15 KHz. This dual-frequency system provides twice as much target information for accurate analysis and identification, ensuring that even the smallest and deepest targets are not missed. \u003c\/h5\u003e\n\u003ch5\u003eThe CZ-21 offers two search modes: a silent-running, slow-motion Target-ID Mode and a hot, Auto-Tune Mode for all-metal searching. Additionally, the V.C.O. No-Motion Pinpointing feature makes it easy to locate targets precisely, as the audio tone increases in pitch and volume as the center of the coil approaches the target. \u003c\/h5\u003e\n\u003ch5\u003eDesigned with user comfort in mind, the CZ-21 comes with a cushioned armrest, a soft foam grip, and a control housing that can be easily removed and hip-mounted. This makes prolonged use more comfortable and reduces fatigue, allowing for longer treasure hunting sessions. \u003c\/h5\u003e\n\u003ch5\u003eWith its big-target alert, faint-target audio boost, and quick manual ground balance, the CZ-21 QuickSilver is a highly capable and user-friendly metal detector. Whether you're a professional diver, a beachcomber, or a land detectorist, the CZ-21 offers the performance and reliability needed to uncover hidden treasures in any environment. Experience the thrill of discovery with the CZ-21 QuickSilver from Fisher® Research Labs.\u003c\/h5\u003e\n\u003ch5\u003eFor more information and to purchase, visit \u003cspan style=\"color: rgb(0, 25, 255);\"\u003e\u003ca style=\"color: rgb(0, 25, 255);\" href=\"https:\/\/firsttexasproducts.com\/pages\/wtbh\"\u003eWhere to Buy\u003c\/a\u003e\u003c\/span\u003e, \u003cspan style=\"color: rgb(0, 25, 255);\"\u003e\u003ca style=\"color: rgb(0, 25, 255);\" href=\"mailto:info@fisherlab.com\"\u003eemail us\u003c\/a\u003e\u003c\/span\u003e, chat with us, or call us at \u003cspan style=\"color: rgb(0, 25, 255);\"\u003e\u003ca style=\"color: rgb(0, 25, 255);\" href=\"tel:1-800-685-5050\"\u003e1-800-685-5050\u003c\/a\u003e\u003c\/span\u003e for any questions. \u003cspan style=\"color: rgb(0, 25, 255);\"\u003e\u003ca style=\"color: rgb(0, 25, 255);\" title=\"Fisher CZ21 Metal Detector\" href=\"https:\/\/firsttexasproducts.com\/pages\/cz1\"\u003eMore Information\u003c\/a\u003e\u003c\/span\u003e.\u003c\/h5\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch5\u003e\u003ca href=\"https:\/\/www.youtube.com\/@FisherResearchLabs\" title=\"Fisher Research Labs YouTube Channel\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0828\/6417\/7432\/files\/yt_logo_rgb_light.png?v=1719851777\" width=\"290\" height=\"65\"\u003e\u003c\/a\u003e\u003c\/h5\u003e\n\u003ch5\u003e\u003c!----\u003e\u003c\/h5\u003e","brand":"First Texas Products","offers":[{"title":"CZ21-10","offer_id":49101158318336,"sku":"CZ21-10","price":1799.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/0061\/files\/CZ21-8JPG2048x2048x202503144.jpg?v=1785435299","url":"https:\/\/metaldetectingstuff.com\/products\/fisher-cz21-underwater-multi-frequency-metal-detector","provider":"Metal Detecting Stuff","version":"1.0","type":"link"}
