Bounty Hunter's Tracker IV detector offers the excitement and profit of metal detecting at an accessible price, making it ideal for those just getting started. With a fully submersible, 8-inch Bounty D-Tech search coil, the Tracker IV features three different operating modes to help you hit pay dirt. Motion all-metals mode responds to any metals you sweep over, full discrimination mode rejects iron and other trash items, and tone discrimination alerts you with one or two audio pitches for different types of metals. The Tracker IV does not have the LCD that many of Bounty Hunter's other models boast, featuring instead a large Sensitivity Meter. Ground Trac, a feature that automatically balances the machine to the soil conditions, makes the Tracker IV a tremendous value. Users will also enjoy Bounty Hunter's comprehensive, easy-to-understand online tutorial and downloadable manual at www.detecting.com. The Tracker IV runs off of two 9-volt alkaline batteries and boasts a five-year limited warranty.
