Abstract
An experimental prototype hand-held detector capable of detecting reinforcing rod and prestressing cable in concrete has been built. The prototype instrument, called MK 1 DREStector, has in preliminary tests consistantly detected vertical and horizontal number 4 reinforcing rod (approximately 12.7 mm diameter) buried at a nominal depth of 0.02 m beneath the surface of a vertical concrete wall. Based on measured sensitivity of the instrument, the MK 1 should be capable of detecting horizontal number 4 rod at a depth of 0.125 m.
