The descriptions here state that this coil is compatible with "All models of Bounty Hunter Detectors." If you bought the awesomeGold Digger Metal Detector here on Amazon, then picked up this little nugget coil, you'll be disappointed to learn that the new little coil has a plug attachment, whereas the Gold Digger has a permanently wired large coil. In other words, you can't attach the nugget coil to that model of Bounty Hunter as claimed! We are the authors of the Prospector's Bible and run the Become a Prospector dot com site and review many detectors for our members, as well as the Gold Prospectors and Miners Assn (GPMAA dot org). To give a positive balance to this compatibility problem, the Gold Digger Detector itself, for between $60 and $80 here on Amazon, and eligible for Prime free shipping, is comparable to $1,000 plus detectors if your objective is gold placer, nugget or lode detecting. Both products are outstanding, we just wanted to give you a head's up that they don't work together! You'll need a more advanced (plug in) model of the Bounty Hunter, such as theBounty Hunter TRACKERIV TK4-PL Tracker IV Metal Detector if you want to use the small nugget coil. However, to be very honest, and save you money, the large coil on the Gold Digger Detector is perfectly adequate for scanning both filtered rocks and below the surface for nuggets. The small head reviewed here is really for a narrow, shallow scan, and is most useful for scanning your filtered rocks before panning the finer dirt or sand. We put a coarse filter over a 5 gallon bucket, shovel the river bed dirt just above bedrock into the filter, toss the stones on the shore, and buzz over them with the detector to be sure we didn't miss a nugget before panning the dirt, or bringing the bucket back home or to base to put through the sluice. If you set your larger coil Gold Digger on object discrimination mode, it will work just as good as the nugget finder to scan your stones, yet with discrim off, read much deeper than the nugget coil to find deeper deposits. Works great with the tracker IV (5 stars), but not at all with the Gold Digger, so a warning three stars just to save Gold Digger buyers a return. If you want the very best anywhere for any and all gold prospecting applications, and one that WILL work with the little Nugget Coil for post-panning rock scanning, the one with the consistently highest performance in our tests, still under $200, and comparable to $1,500 models at Cabela's, is:Bounty Hunter Quick Draw II Metal Detector -- in fact, there is a "Cabela's Only" special make up privately branded of this exact model for three times the Amazon cost!
