PREFACE: Gold Detectors are ALL Metal Detectors that respond to ALL metals, be it Gold, Copper, Lead, silver, Nickel, Iron etc. There exists NO Technology Detector that will find JUST Gold and Ignore all other metals. There are however subtle tips and tricks that your Local Dealer knows to help you to Differentiate metals.
Above, Grand Master Detectorist, Jimmy Sierra showed, above pulling out a
gold nugget in California GOLD country.
What makes a Metal Detector an Effective Gold Nugget Detector is based on the detector's circuit design, frequency and ability to handle changing difficult ground conditions. A Manual Ground Balance is a must, otherwise your ability to hear that deep gold nugget is almost impossible.
Your VLF Detectors are the most popular. On the other hand MOST metal detectors will hear the GOLD nugget provided that it is large enough to be detected in lieu of the model metal detector being used. Don't expect a Cheap Low Frequency detector to detect that average GOLD at 5" in the ground because it will not. There are many other Factors that determine whether your going to be successful with your GOLD Detector. Please contact me to make an appointment and I'll give you a Free Demonstration.
Another type of Gold Detector is the Super PI or Pulse Induction detector. Their strongest advantage is their ability to virtually ignore most hot rocks and difficult soil condition that will challenge most General Purpose Metal Detectors. Generally, the Super PIs from Minelab and White's have been developed to hear the very small nuggets and will hear deeper because their PI Receive Circuits are so Quiet in Difficult Ground that can Challenge the BEST of a VLF Detector like a Goldmaster GMT or Fisher Gold Bug PRO, II, Tesoro Lobo Super Traq.
My Recommendations in Order of Manufacturers...
White's Electronic s Limited Distribution: Goldmaster Sierra GOLD Trac: White's Newest Limited Distribution Model for 2013.
ALL the Horsepower and Depth of the GMT but simplified with JUST Two
Controls. Retailed at just under $600.00, Jimmy Sierra is offering a
introductory coupon available on line for $100.00 off or under $500.00!!!
There is nothing that will come close to the performance of this
particular model, price point in tackling some of the worst ground
conditions. Standard with the Wide Scan DD 6x10 coil, it will hit hard on 1 grain nuggets. Add a 4x6 DD Super Shooter Coil and we are talking 1/10th Grain Folks!!!!
TDI Pro: Dual Ground Balance Control, Pulse Rate, Frequency Control, Dual Tone ID with High ALL Low Conductor Switch handles the California Gold Areas to Western Australia. Threshold is a BIT wobbley at HIGHER Gain Levels but Deep and Effective whether your in Gold Country or at the Black Sand Beaches of California. I retrieved a Nickel at over 20 inches using a Sierra TDI T-Foot. Priced under $2000.00
TDI SL: Newest in the TDI series. VERY quiet on higher gain levels and developed to be used with NMHI Battery Systems. Much Lighter in Weight but has a Single Turn Ground Balance. My current choice in Gold Prospecting and Beach Hunting. Makes an exceptional coin hunter but training is definitely warranted. Priced under $1500.00 with choice of a Dual Field 12 or 7.5
Goldmaster GMT: White's Flagship VLF Detector operating at 50 kHz ensuring extreme sensitivity to even sub-grain nuggets. The GMT employs a State of the Art Ground Tracking System along with an IRON v NON-IRON LCD and Follow the Black Sand Mode and overall Ground Strength Indicator. Not recommended for heavy alkalai due to the high sensitivity but excels in California Sierra's difficult Red Dirt and Arizona Deserts.
White's MXT Series: A general purpose detector, it sports three separate programs; Coin/Jewelry, Relic and PROSPECTING. At 15 kHz, its Target Response on a 2 Grain Number is reduced compared to the GMT or GMZ, however, MATE this unit to an optional 4x6 Eclips Loop and you would be hard to tell the difference. It has a Back Light and Ground Grab to Supplement its sophisticated Auto Track System. If you want just one detector that can do it all under $1000.00 including effective Prospecting, the MXT PRO is the Bomb.
GPX 5500: Industry's Quietest Super PI and Well Deserved. Currently the Detector of Choice in the Australian Outback and Deserts of the US. But for its ultra-expensive price TAG of $5000.00, I'll recommend any of the White's TDIs. I've checked with Digger Bob, a former Minelab Dealer who promotes the
White's Super PIs and has conducted so many comparison tests in his Test Garden and out in the field. The Minelab ULTRA Stable Threshold seems to make the difference of hearing those fringe targets up to an 1" on average more than the competition. Earlier models were a bit noisier and prone to Lightning Strikes as far away as 2000 Miles bouncing off the our Troposphere. The latest GPX 5500 has seemed to have been resistant to that noise.
Drawback on the this Platform is you have a voluminous amount of Timing Swtiches and Controls so the wrong Flip and you have Digitally cancled out that Nugget depending on a variety of factors. White's TDI Series seems to be more straight forward and error Free in this respect. Although Minelab has struggled to reduce the Weight of the Unit and Simplify, you can go wrong and lose that edge if you lack the guidance of a professional like Larry at Big Valley, and if weight factors into your choice, it is still significantly HEAVY compared to the White's, Garrett, Competition.
Lobo Super Traq: Very Smooth Tracking, similar to White's GMT and MXT. Tesoro's LST can be Belt Mounted, Rear Poll Mounted or Chest Mounted giving you additional flexibility and enable you to Shallow Water Wade without fear of dropping it in the water. Operating at 17.5 kHz like its sister unit, the Tejon, response on small nuggets is decent under 2 grains but not the strongest in the industry. A 120 Degree Discriminator enables you to check loud surface targets to readily identify Ferrous from NON-Ferrous.
Tejon:Same Frequency as the Lobo Super Traq but is manually ground balance and uses a concentric coil which is not recommended. Better off to purchase a Small or Large Wide Scan Coil to Calm that noisy ground.
Vaquero: Very Smooth Operator with Manual Ground Balance operating at nearly 15 kHz, similar to White's MXT with the Prospecting Program. Performance is adequate and it can handle most mineral environments for its lower Price Point. Wide Scan Accessory Coil Advised.
Sand Shark: Although not marketed as a Gold Prospector, it will Ignore Most Difficult Mineral and deliver on about 3 Grain Size. I recommend the 8" open Loop Mono as it will hit harder than the 10".
Outlaw: Operating at 10 kHz, not the hardest hitting on smaller nuggets but still quite capable with its manual ground balance, auto tune assisted single filter all metal mode. The Outlaw can be purchased with the Optional Three Coil Pkg, a Great Value for discounted pricing of just over $500.00. Coil sizes are 5.75" for Trashy Areas, 8" for Parks and a Larger DD Coil for Beach and Prospecting.
When it comes to the Super PI Class, the Garrett Infinium is currently the only Submergeable Gold Detector but watch out. Alternatives are right around the corner from White's Electronics. A Variety of Different Size Search Coils are available. There is some Ground Slur Response brought on by a Lack of Manual Ground Balance Control. At $1250 List and Mapped at around $1000.00, a very good detector at the Beach or Gold Fields. Garrett is scheduled to introduce a new model in October which is submergible to 10 feet and has added ground tracking. Seems to be quite sensitive to smaller nuggets and difficult shape nuggets to boot. At $3000.00 the new detector is not cheap but is targeted toward the Minelab Model.
A water resistant, submergeable to 10 Feet and VLF operating at around 18 kHz +/- with semi-auto ground balance control and a Small but Detailed LCD Display. Lightweight and
will definitely cut into Fisher Gold Pro Sales. I love that AT-Gold smaller DD coil.
Fisher Metal Detectors
Fisher Gold Bug II employed a much higher frequency when it replaced the original Gold Bug back then as it's Flag Ship Unit. Its 72 kHz is a bit High for its current design but it is among the smoothest manual ground balancing detector optimized for Gold on the market today. Fisher wrote the book on the 1980s by coming out with the 20 kHz Gold Bug One that set the Standard. The Gold Bug II still hangs in their but better technologies are competing against it, like the Gold Bug Pro. Teknetics has a sister unit, the G2, that employs the smaller Wide Scan as a Standard Coil which has been well received.
Fisher Gold Bug Pro operates at under 20 kHz and features a Smaller Than average Coil at just under 6". Don't let a Small Coil fool you... although lacking area coverage, that coil can get in areas that large coils dare not go. The response on my Black Sand Puck Test was impressive and its Semi-Auto Ground Balancing works great. Caution however, it seems to be slightly speed sensitive so scan the ground slowly or Risk losing that nugget. Nonetheless,
