I am just curious how come only one company makes a target probe for metal detectors? There are several companies that make just about every other item for all brands of detectors including coils, headphones, rain covers, harnesses etc. But only one company that makes a probe. Now that they do not make a probe for the minelab explorer series anymore it seems some one would start producing them. I do not believe it would infringe on any copyright laws because several companies manufacture coils for all different machines and a probe is basically a miniature coil right? For what a used x-1 explorer series probe is going for when they come up for sale it seems like it would be worth while for some company or some one to start producing them. Any opinions?
