The E-Trac is Minelab's most technologically advanced metal detector. Its industry-leading comprehensive targeting options set it apart from any other detector on the market. Full Band Spectrum technology processes simultaneous frequencies from 1.5kHz to 100kHz with a high-powered microprocessor. Any signal detected is analyzed with a wide range of responses to judge the ferrous and conductive properties of your target. Along with two-dimensional Smartfind , which graphs ferrous characteristic and conductivity for quick and easy assessment, the E-Trac lets you eliminate undesired signals for more accurate identifications at greater depths and offers higher sensitivity with less interference. Adjust the automatic ferrous and conductivity rejection level with QuickMask and refine the detection threshold on a precise 1 to 50 scale. The adjustable Trash Density level lets you increase signal discrimination to eliminate false signals in highly littered environments and reduce selectiveness in bare fields for quick target fixes. The E-Trac Xchange system lets you use a USB interface to download and upload E-Trac settings, user modes and discrimination patterns with your own PC. It also lets you build a resource library to chart your progress. Ultralight, waterproof, 11" Double-D coil. Crystal clear, sunlight-readable 72mm x 48mm display. Balanced, ergonomic handle assembly reduces fatigue. Intuitive icons, logical menu choices and user-centered keypad design for premium ease of use.
