The technology behind a gold detector
One technology used for finding gold is the PI, or Pulse Induction, metal detector. Black sand or fine metallic mineralization is the main problem that encountered with typical detectors. PI units can ignore these deposits and separate out the yellow substance.
VLF, or Very Low Frequency detectors are also useful for the job. This is the most common technology used for gold detectors. These metal detectors use ground balancing to separate the readings in mineralized soil.
Minelab Eureka Gold
Using VLF technology combined with Minelab's own patented technologies the Minelab Eureka Gold metal detector is a top performer. Kellyco offers the Eureka detector at a discount price and includes a high value accessory kit for only $988.59. Find only one ounce of gold and the metal detector and trip to the field is paid for.

A quality unit that operates at 19 kHz. This is Fishers' top of the line gold nugget shooter. Capable of ground balancing even salt this is a great machine for use at the beach. Purchase this versatile detector at Metal Detector Depot for only $699 including shipping.

The Garrett Gold Scorpion Stinger is the perfect detector for those seeking quality on a low budget. Available at the A&S Company for $467.45 with free shipping. This highly stable device operates at 15 kHz and uses an elliptical search coil that can detect very small gold flakes.
Tesoro Lobo SuperTRAQ
Another quality instrument operating at 17.5 kHz is the Tesoro Lobo SuperTRAQ. With computerized ground tracking and no-motion pinpointing this detector makes finding gold a pleasant task. AK Mining sells this fantastic metal detector for $679.95 with free shipping.
Conclusion
In order to locate the most gold, no matter what method is used, it must be done in a known, gold bearing, region when looking for alluvial gold. Researching the areas is an important first step. The Internet has numerous geological resources available. Gold bearing regions are well known and documented in detail.
Gold jewelry and coins can be located most anywhere that such items could have become lost. It is rare to find gold coins since few people would be careless enough to lose them. It is possible that someone may have buried their savings in the back yard and never returned to reclaim it.

I like the idea of no-motion pinpointing. You use to have to swing the things back and forth and up and down... ad nauseum. I didn't realize they had metal detectors out there primarily for detecting gold. Cool.
My husband and I have panned for gold with limited success. We have toyed with the idea of purchasing a metal detector but had no idea as to which one would be the best one for our money. Your article was a big help!
