GD-C Portable Ungerground Water Detector
Application:
u Metal and non-metal ore survey
u Decrease mineral invest venture and increase exploration success rate
u Underground water detect
u Meet demand of drinking water, industrial usage and agricultural irrigation.
u Engineering geological prospect and disaster geological detect
u Coal goaf, archaeological mining, city exploration and non-metal pipe survey
Main features:
u Fast and high efficiency
u Easy to carry
u Easy operation
u Good precision and high accuracy
u Very practical and low cost
