It will always find gold if it is there to be found. Dec 12, 2009
By M. Sabo I made purchase of the GB2 because of what I researched it can do. It has been stated to be able to find gold as small as a pin head. The GB2's ability to locate gold say 0.02 grams is on or 1 inch near the surface. Reported depth is around 4 to 5 inches with a 1.0 gram nugget. I wanted the 6 1/2 inch search coil that is very small because the larger coil looses the ability to see the smaller gold. I needed a detector that has a smaller search coil and the GB2 is it.
The GB2 is not a perfect detector as with any other in comparison. If the decision is the GB2 or the GMT or the LOBO a person can not go wrong choosing any of these detectors. I own a GMT and it can give the GB2 a challenge. As for the LOBO as I have read it will detect deeper by what I assume to be around an inch or so but at the risk of finding no small gold. The GMT will go deep and find small gold too. If there is very high mineralization all detectors will struggle unless it has the ability to ground balance it out. There is a limit to the design of the GB2 as with the others. Taking the GB2 to the beach may not be a good idea but it should work there, but not as well as in a low mineralized area. The GB2 is stated as being able to find invisible gold. This type of gold is spongy or that which is running through quartz that some detectors may or can not find. Whatever the case I had to get a GB2. There is a newer version that I will call GB3 but it is not being well recieved. The operating frequency is lower and the coil is round again. It would be nice of Fisher to make available a small round coil for GB2 but at a low price though. The original GB had the small round coil.
The detector is light. It is packed with the two 9 volt batteries already there. Assembly is pulling the composite rod down and joining the upper and lower shafts then unpluging the cable and wrapping it up in place. Nice, it is good to go. The control boxes housing is plastic. The batteries are held in place with little plastic doors held on by a thin plastic line. I don't like plastic and will have to be careful here. Here is where the GMT shines. Construction is much better. You can't go wrong with the GMT, but you will still want a GB2.
Update: There is a plastic plug for the headphone jack. It's there to help control debris from getting in. The plug keeps falling out and I'll keep pushing it in till it either stays or breaks. As I said, It's not a perfect detector and I don't like plastic.
