If you are looking to find gold nuggets this is not the answer. This is no different then the one already on your detector. I tested it and it worked no differently then the one that came on your metal detector. If you need it to get into smaller spaces then it will work for that purpose but it will not pick up gold nuggets unless they are whoppers like 5 grams + and that is rarely found. Even then your other coil that comes with your bounty hunter would work the same as this little one. I would not invest money in this unless you need it for small spaces. This will not pick up small nuggets. I am a avid miner and have tested it on gold. save yourself the $40 and save up for a tesoro compadre which will pick up small nuggets and it is only $160 free shipping on amazon and ebay. This also does not have the bounty hunter sticker on it so it is a knock off and false advertised in my opinion.
