Meet the AKYOR CSP86 Metal Detector: a smartphone based solution with a compact design that lets you differentiate between different types of metals. It has programs to target gold, silver, ferrous, and non-ferrous items. The device only weighs 2.5oz.
The CSP86 is powered through the headphone jack of your phone, so it doesn’t need an external battery. It can be used to search walls and ground for treasure.
