Bounty Hunter's 4 inch coil for gold

[gold_geologist2011]

I was looking on ebay the other day for a smaller coil and happen to see there was a coil for bounty hunter detectors that worked for gold nuggets. Has any of you tried using one of these? How do they work out in highly mineralized ground? http://www.ebay.com/itm/BOUNTY-HUNTER-4-INCH-NARROW-FIELD-SEARCH-COIL-/250912912905?pt=LH_DefaultDomain_0&hash=item3a6b933609

The way that ad is worded is kind of misleading even though what's written is accurate. That's a standard BH four inch coil and it does have a narrow search field compared to larger coils, but only because of it's size. It is more sensitive to small objects, but that's also because of it's size. A detector transmits the same amount of energy regardless of what size coil is used, the smaller the coil the more intense the transmitted field, and the result is that small targets are more easily detected. Small coils work better in bad ground for the same reason. They see less ground than larger coils, which means they also see less mineralization. The ad doesn't mention gold nuggets, most likely because that coil is for the lower frequency BH models and frequencies of 15 khz and higher are used on detectors designed to hunt nuggets.

I do have a lot of areas that I hunt that has a lot of trash. This coil will be beneficial for separating close objects. Apparently, some people have found some gold nuggets with them...At least that's what some of the testimonials say. Since I got this for coin shooting, I would love to at least test it out with finding gold nuggets and see if it works...If not, ill just break out my sluice ; )
