The Big John Metal Detecting Relic Spade is designed for detecting in fields and parks where you may have to dig a deeper hole than what a hand digger is capable of. It is made from 2mm grade 204 stainless steel and has been manufactured with quality and strength in mind. This shovel features serrated and sharpened edges which makes for easy cutting through roots, sods and wads. The shovel or blade part of the relic spade is tapered from top to bottom enabling you to pull out a neat plug. The angled and curved blade lessens the chance of mud and clay sticking to the shovel as would be the case with a flat shaped spade.
