When we correspond on line not all things are clear. My metal detector may work different than yours. If you're looking for gold and the machine you use can detect small pieces of gold you will need to dig foil, lead, copper or any alloy for that matter. If your machine can't detect small gold, which is what they have most of out there, don't worry about it. The metal detector I use is a detected gold machine. That means that it's designed to find gold nuggets, but doubles as a great gold jewelry and relic machine.
My machine can identify small bits of iron, larger pieces of common iron are hard to identify. The way I identify nails/bobby pins or similar shaped items that are not gold on my machine is by listening to the threshold tone. They will interrupt the threshold tone on my machine with two beeps when the coil passes over them long way.
Each machine has different tricks. I've read good reviews on the machine you have. The best thing to do is read the manual, the Reviews and the likes.
This is how I set up the GB-2 for hunting:
[*]Both toggle switches in the middle position (Normal)
[*]Sensitivity all the way up unless the machine won't balance but never below 8
[*]At this point the volume and threshold on the machine should be off
[*]I start with the volume all the way up on the earphones
[*]Now I turn the volume all the way up on the GB-2
[*]Then I turn the threshold on the machine up until I can barely hear a smooth tone (the tone should be as soft/low as you can get it but smooth)
[*]Now I turn down the headphones to a comfortable position (don't turn down the machine).
[*]Now I’m ready to balance the machine and start hunting
[*]After I start hunting and hear a solid target I check it out with the Iron Discrimination. If I get a positive response in ID mode I dig the target. Simple
After 3 years I have over 70 (over 4 ounces) gold finds and my silver coin count is going up by the week. It takes a long time to learn the sounds, but it pays off to keep with it. The GB-2 works better on scrapes, demolitions, parks, campsites and the like.
The only machine I’ve ever hunter with is the GB-2. I quit counting clad after the first 14 months it took to find enough to pay for my machine. I’ve sort of wavered away from parks and schools, but when I need a gold fix I hit the playgrounds.
This can help you too. Thanks goes to
Mr. Jim McCollouh of whom I quoted this from:
Operating frequency DOES influence several detecting factors, notably "bias" toward target conductivity, sensitivity to soil mineralization, and sensitivity to target SIZE. SIMPLY put, the higher the operating frequency (higher: 50kHz is higher than 20 kHz) then the following characteristics apply: greater sensitivity to low conductivity targets, greater sensitivity to smaller targets, but, sadly, also FAR greater sensitivty to soil mineralization. The lower the operating frequency, the greater sensitivity to higher conductivity targets, reduced sensitivity to smaller tagrets, and enhanced penetration in soil mineralization. THUS: a detector operating at 5 kHz would penetrate mineralized soil WELL for silver coins, but would not be very sensitive to small targets, or those of lower conductivity, such as gold. A detector operating at 50 kHz would be great for small targets, gold targets, but might loose depth in highly mineralized ground. Hope this helps; HH jim
