GoldPic: Pulse induction metal detector

GoldPic was in development for 24 months. The third generation design has been extensively field tested on Clifton Beach near Cape Town and is now available in semi-kit form. The machine was designed to detect coins and jewelry on the beach and in shallow water. The timing and circuitry is optimised to detect small items like coins and rings at a good depth.

The development was done as a ‘midnight engineering’ project. Published designs failed to provide the sensitivity I required to search the soft deep sand on the Atlantic Ocean beaches around Cape Town. The kit is designed to be easy to build, using readily obtainable low cost electronic and mechanical components.
