An Interview with Minelab Engineer Mark Lawrie
The design of metal detectors well-suited for prospecting is an interesting process and not necessarily an easy one to achieve. It is a combination that blends the desires of what prospectors would like, the requirements of sales people and dealers, with the science and physics of what the electronics can achieve.
Reminder: Annual Claim Filings Due
