NUGGET FINDER ADVANTAGE COILS

Professional Grade Search Coils for the Serious Prospector

Nugget Finder is an Australian based company that specializes in building after-market coils to suit the MINELAB gold detectors. They use only the best quality components to produce the lightest, high performance search coils on the market. Nugget Finder offers a full range of both Elliptical and Round Monoloop and Double D search coils designed specifically to enhance the MINELAB GPX/GP/SD Series metal detectors. Their newest design is the ADVANTAGE Series.  

NEW FEATURES FOR 2010:

1. Fully Bonded Construction - All the components that make up a Nugget Finder Coil are bonded. This dramatically reduces false signals when the coil is bumped against rocks and bushes. A further advantage is a coil that is rigid and doesn’t flex or wobble. Even though the Advantage Series has more wire and a stronger design, weight remains roughly the same as the previous models. This was achieved through innovative design not by cutting corners!

2. Litz Wire – All Nugget Finder Coils are wound using Litz wire; a multi-strand wire in which every individual strand is insulated before being wrapped in a cotton or Rayon coating. The insulation prevents the windings from creating eddy currents and thereby “seeing themselves” and transmitting a false signal. Litz wire has an advantage over other wire because its’ high surface area gives it a greater transmission ability. Litz wire is more expensive to manufacture with, but the end result is a more powerful, energy efficient coil. Most other coil manufacturers do not use Litz wire.

In addition to Litz wire, Nugget Finder has also added modified shielding to the Advantage Series which offers better resistance to Electromagnetic Interference (EMI). Another benefit has been an increase in sensitivity and signal response on small gold, and improved stability; particularly on the GPX-4500 and 4000 models. 

3. Water Resistant – All Nugget Finder Advantage coils are a fully sealed. The new O-Ring design with sealed cable makes them water resistant to a depth of 2 feet. Now a person can detect streams, creeks, puddles, and wet grass without fear of causing damage to the coil.

4. Potted Windings – The heart of any coil is the winding. It is vital for coil performance, stability and longevity that the windings be held firmly in place. Coils without potted windings will experience a higher level of “falsing” when the coil is bumped into obstacles while detecting. Nugget Finder overcomes this problem by encasing the entire winding in a super hard resin that allows absolutely no movement for the entire life of the coil.

5. Epoxy Reinforced Polyurethane Bracket – Unique to the Nugget Finder line are their super strong brackets or coil shaft mounts. Unlike other manufacturers that form their brackets out of the same plastic used to build the coil, all Nugget Finder brackets are actually anchored into the core of the coil itself and transfer any strain into a High Density Foam Center; making them the strongest on the market!

6. Experience & Goldfields Based Testing - With over 16 years manufacturing experience, a strong emphasis on Research & Development, and immediate access to some of the best and most highly mineralized goldfields in the world, Nugget Finder has the knowledge and resources for producing the highest quality of aftermarket products.

7. Full 2-Year Warranty – Nugget Finder Coils are the only coils in the industry to come standard with a full 2-Year warranty and protective skid plate!

The History of Nugget Finder Coils:

Nugget Finder Coils were first manufactured in the early 1990’s, by Barrie & Rohan Johnson of Barrie Johnson Detector Service in Wedderburn, Victoria; a small country town renowned for its’ rich goldfields. Consisting of a small range of lightweight, fiberglass coils, these products were very popular amongst the Australia prospecting community. Constructed entirely by hand, Nugget Finder offered prospectors high performance coils without the excessive weight associated with similar sized coils manufactured from plastic.

Nugget Finder continued to produce coils for the VLF series of Minelab detectors until the introduction of the Minelab SD2000 in 1994. The SD2000 had an overwhelming impact on electronic gold prospecting in Australia. This new generation of Pulse Induction machines quickly replaced the earlier VLF models as the pro’s choice for hunting nuggets. Barrie Johnson Detector Service began manufacturing a new range of add-on accessories for the SD series under the Nugget Finder label, such as sound enhancers, external speakers, and battery packs.

Over the following years Barrie & Rohan Johnson received many enquires from prospectors eager for a new range of large, lightweight coils to suite the Minelab gold detectors. Field testing of these prototype coils began in late 2002 with incredibly positive results. By mid 2003 Nugget Finder coils were again in production, with demand quickly outstripping supply. To accommodate the increased demand, Nugget Finder moved to a larger facility in nearby Bendigo, where all manufacturing continues to be done entirely by hand – no automated steps are involved at any stage of construction.

Nugget Finder is constantly field testing and listening to customer feedback, they take pride in their work and aim at making only the finest search coils. ARIZONA OUTBACK is the sole North American Distributor of the Nugget Finder line, with authorized dealers across the nation.
