The metal detector will come handy, when searching for coins or small metal objects, but also when checking underground pipelines or detecting cables. It has quite a long adjustable stem with a nice adjustable armrest and big controller unit. You can tweak the search modes and sensitivity to your desire and with the connected headphones your search will get even easier. The search coil itself is waterproof, so you can even go for adventures in shallow waters. But the main body is of course not waterproof so no diving expeditions are possible.
No matter if you a wannabe treasure hunter or an avid amateur archeologist, this gadget will certainly be right up your alley. The pricing can also quite surprise you, because getting such advanced metal detector is not expensive at all. Current Aliexpress sales can slash the price of MD4030 just to $38.99, which is an extremely affordable offering. So pick up one and go search for the next treasure chest !
