| PREFACE: Gold Detectors are All Metal Detectors, that respond to all metals, be it Gold, Copper, Lead, Silver, Nickel, Iron etc. What qualifies them a s 'Gold' Detectors is that Gold generally is found in difficult ground-mineralization so the metal detector must have the proper controls to deal with the ground conditions which can be noisy and obscure the metal detectors ability to 'see' gold nuggets in the ground. In order to neutralize this ground noise the Gold Detectors rely on ground balancing circuits, either Auto Tracking or Manual Ground Balance. Second important factor is the frequency of the circuit. VLF Detectors optimize to sense gold nuggets (the average size in California is about match head or 2 to 3 grains), they tend to be at a higher frequency than your traditional coin metal detector, about 10 kHz to 72 kHz. Pulse Induction Detectors strongest advantage is in their ability to virtually ignore most hot rocks and difficult soil conditions that will challenge a high end VLF Detector. The Four Major Brands Recommended by Trans Bay Metal Detectors by virtue of their Quality and Technology are Tesoro, Garrett, Minelab and White's . NEW for 2009 White's GMZ. 50 kHZ, Under $500.00 5 years in Developing and Testing * Silent Search, No Threshold * Ultra Battery Efficient * Enhanced Signal Response on the Smallest of Gold Nuggets * New Ground Balance Range Control.... Set it and Forget It! * Salt Mode for Alkalai and Even Beach Hunting Light Weight, about 3 lbs SL Housing Note: Just Received Several Units... Limited Distribution White's Goldmaster GMT, 48 kHz, Under $800.00 Auto Tracking Ground Balance with Manual Ground Balance or Quick Grab Ground Balance, Variable Auto Tune or Self Adjusting Threshold. 6x10 Wide Scan Search Head. VCO The Pole Mounted GMT delivers an impressive audio response on nuggets down to sub-grain size. The ground tracking system is fast and efficient. The GMT sports a unique visual identification system that indicates the percentage of iron in the target from 0 to 100%, the amount of mineralization and amount of black sand concentrations. Note: Last summer, I hunted with a GMT at Lake Tahoe looking for finer jewelry and scored a 1934 Peace Dollar, 1942 Mercury Head Dime and a 6 Diamond 18K Gold Ring. The Goldmaster made its debut in 1990 as the Goldmaster II. Subsequent Models were the Goldmaster V/SAT, Goldmaster III and Goldmaster 4B. Copies of my book, Understanding the Goldmaster V/SAT are available by Email Request @ au4greg@sbcglobal.net through 2008. White's Pulse Scan TDI, $2000.00 See White's Web Site, with Entry Price of just under $1600.00. Comment: Unbelievable Depth. Super Quiet over all ground conditions with a Manual Ground Balance. This is White's latest model, two years in development. Eric Foster is considered by most, the 'Father of Pulse Induction Technology' and joined forces with White's Electronics over two years ago. The TDI shares a similar platform to Eric's limited distribution Gold Scan 5C ($2500.00) but with several White's advancements thanks to project engineer, Dan Guyer. * Doesn't see Hot Rocks like most of the competitors. * Extremely quiet under atmospheric conditions or power lines thanks to its Analog Circuit and Frequency Adjustment control. * Patented Twin Transmit Field Technology in Loops... White's First. * Standard 12" & 8" Dual Transmit Loop Standard with 8" & 4" on its way. * Patented High Conductor (Low Tone) or Low Conductor (High Tone) Switch... White's First * Convertible Chest, Hip or Pole Mount exceptionally balanced light weight and superior configuration compared to other non-White's Models. * Dual Lithium Ion Batteries with charger * Full Range Gain Control * Adjustable Threshold Control * Adjustable Ground Balance * Ability to Run Straight Pulse * Adjustable 10us, 17.5us or 25 us Pulse Rate * Designed for Gold, Relic, Beach. Note: Trans Bay has been selected to author some Professional Tweaking Tips. Sold only directly through Select White's Electronics Dealers. When Depth is your priority, TDI's performance over Surf and Turf conditions is unsurpassed. This 'Hunt By Ear' regularly finds coins in excess of 15 to 20" in the most difficult of soil conditions whether its the Black Sands of Half Moon Bay to the Red Dirt of Paradise, CA... just ask Bob Van Camp, Paradise Detector Sales, and White's Electronics Expert. Garrett Infinium, $1250.00. The Super Detector, Fully Submergeable Comment: Water Proof to 200 Feet or more and Ergonomically much lighter and easily pole or hip mounted. The circuit sounds very close to the Minelab 2200 and appears that Charles Garrett and Engineering Staff likewise took a page or two out of Eric Foster's Technology. Several months ago, Mark the Locksmith, one of my customers, traded in his Detector PRO Head Hunter PI (Eric Foster Circuit) in which he found a man's gold ring with two 1/4Ct Diamonds at over 14". Mark had been doing his homework and asked to borrow my Infinium Demo and liked the High-Low Conductive Tone ID and had me order one for him. After he received the new Infinium he remarked that this new Infinium seemed to be more stable and apparently checking with my National Rep, Carl Mathias, Garrett has quietly continued to make improvements in the development of the Infinium with little fanfare. The Infinium also has a wide selection of Factory MONO and Double D or Wide Scan Loops available. Three Years ago, I took my Infinium to Lake Tahoe and it cut through the heavy volcanic black sand with ease. There were coins i just couldn't get to that were over 20". The infinium is definitely a best buy.
