<p>[QUOTE="Roughwater, post: 7795446, member: 122150"]There are several types of Metal detectors but in general, a pulse induction will go the deepest. Minelab makes some of the best of the PI detectors. However Whites made one number of years back. I had one and made myself a one meter coil that worked very well and would go very deep with using the whites PI. I am fairly sure if one were searching for a Mason Jar size object 3 Ft would be possible with a one meter coil. You need a little electronic skills to build one and a digital meter that can read inductance. I used PVC to put the wire in and made it rectangular. Most serious gold detectorists use PI detectors and most use Minelabs. I haven't been keeping up with gold prospecting for a while but the downside to PI detectors is lack of discrimination. As to coil building it isn't completely necessary to do as there are pretty large coils out there if you are willing to pay the price. One reason I mentioned the whites however is that not everyone has the money to get a top of the line Minelab but a person could pick up one of those old Whites PI detectors at a much more reasonable cost and they will go deep. their downside was that they couldn't beat the Minelabs at sensitivity and 90% of the nuggets folks find are tiny so sensitivity is very important. This is an edit -- I'm sure the Vanquish is a great detector but it's not a PI it's most likely a VLF. Minelab don't make a bad detector and a VLF detector in general is much less expensive and better at coin hunting (unless you love digging up every thing in the ground). It can get pretty weary pretty quick as 95 % of what's in the ground is trash. Pretty much the same in the sand. PI's do however in general work better in mineralized ground than a VLF detector.[/QUOTE]</p><p><br /></p>
