Do you have difficulty finding ores with a regular Prospector's Pick? Perhaps something here can be of help...
Precision Prospecting adds three additional prospecting tools, each with different ranges, which can be used to enhance your prospecting expeditions.
The Prospector's Hammer is similar to a regular Prospector's Pick, just with a smaller range.
The Prospector's Drill is a directional prospector which has a non-cubic, off-center scanning area
The Mineral Prospector has a larger scanning area, but only detects non-metal ores.
