Epx5288 Epx7500 Epx9900 Underground Gold Diamond Detector
1. Product Introduction about EPX9900 Underground Gold Diamond Detector 1.1 EPX-9900 is the newest upgraded version based on EPX-5288. We add functions of adjusting sensitivity, auto frequency selection and calibration to it and LED screen. Make the operation more convenient. The English operation panel becomes more beautiful. 1.2 The detect target becomes 7 kinds of metal:Gold,Silver,Copper,P.G,Tin,Aluminum and Precious Stone.  1.3  EPX-9900 is an advanced Detector System utilizing advanced OKM-SONO-GAUSS technology. This detector was first used in the field in 1984 and the OKM-SONO-GAUSS technology that it uses has proven to be (by far) the most successful.  2.Specification for EPX9900 Underground Gold Diamond Detector  1 Max Detection: 1-50m 2 Detect Range: 100-1500m 3 Rechargeable Battery: Continuous working over 72 hours 4 Power: 850mA 5 Frequency: 433 MHz+/-150 KHz 6 Inner Storage: EEPROM 16k*8Bit 7 Voltage: 9~12VDC 8 Temperature Range: -40°C~85°C 9 Operating Humidity: 0~95% (non-condensing) 10 Ultrasonic Frequency: 400-3000 MHz+/-150 KHz 11 Weight: 14LBS Please note that: 1)  After select a detecting target, adjust the frequency to the minimum frequency value which is reflected by the geographical environment. 2)  Because the different reaction of geology and mineralization, such as: gold, silver, copper, pyrite, iron, lead, zinc, and groundwater, pls. start to detect from the minimum frequency. If the mineralization interference intensity, pls. choose the corresponding intermediate average to detect. Choose the best suitable detection frequency. Photo: Â
