Design Features Include:
- New coil housing made from U/V treated ABS plastic
|
- High performance Litz wire is used on the internal winding. Litz wire is roughly 5 times the price of the standard copper wire used by the competition
|
- The core of every coil is bonded to the plastic to eliminate movement inside the coil
|
- Epoxy reinforced Polyurethane brackets. These brackets are anchored directly to the core of the coil; this reduces flexing on the shaft and prevents cracking on the plastic which is common in traditional vacuum formed plastic coils
|
- Tight custom fitting molded skid plates. These skids also have rounded edges to reduce wear
|
- Better skid plate tape that doesn't stretch and is waterproof
|
- Most spoke-type coils are solid, or resin filled. Nugget Finder spoke coils are foam filled with fully potted winding to minimize weight while maintaining strength and performance
|
- Improved finish - no smudges or surface imperfections
|
- Standard off-white color to reduce heat absorption

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 SD and GP series. 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.
What Are The Nugget Finder Advantages?
Nugget Finder use only the highest quality components in their coils, with every step being performed by a small number of skilled staff. 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 winding in Nugget Finder coils are potted in a very strong resin which provides waterproofing and protects against damage and movement.
A constant problem with vacuum molded plastic coils is cracking of the plastic at the shaft mount caused by flexing during use. This flexing is more pronounced with larger sizes as the coil can wobble and tilt making it difficult to control in undulating terrain. To overcome this, Nugget Finder use a separate Polyurethane shaft mount which is reinforced with a super strong fiberglass epoxy. This separate mount is bonded to the coil and is actually anchored through to the core using plastic clips set in resin. The result is a shaft mount that is very rigid and strong while removing all stress from the outer casing of the coil. By using a flexible urethane there is no need for a heavy-duty bolt and wing nut as the shaft can be tightened easily without the need for undue force to be applied.
Operators of Nugget Finder coils will note the position of the cable close to the shaft greatly reduces the instances of sticks and bracken being caught by the cable. The skid plates on all Nugget Finder coils are made from high quality ABS plastic. This plastic is very hard wearing and impact resistant, combined with rounded edges these plates will save the operator time and money with less frequent replacements required.
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. We encourage you to find out for yourself why more professional prospectors across the globe are making the switch to Nugget Finder.
Nugget Finder Warranty Policy
For up to one year after purchase, Nugget Finder will, at their option, replace or repair any coil found to have a manufacturing defect. Examples of manufacturing include: coil malfunction, extreme reduction in sensitivity (will be obvious), or electrical shorts. Examples that are NOT covered are: normal wear and tear (this includes chips, dents & dings), coil skid plate wear, problems resulting from submersion underwater, problems resulting from coil tampering (i.e., cutting open coil or trying to lengthen or short coil cable wire).
Make sure you are given an NF Warranty Card; this should be provided by your Dealer with each coil purchase. VERY IMPORTANT: make sure the warranty card is filled out completely and mailed in; especially the Date of Purchase and the Serial # (if it is not already done). The coil Serial # can be found etched into the black bracket which attaches to the shaft. Keep a copy of your sales receipt. If the Dealer fails to issue one, ask for it. Your warranty card and sales receipt will serve as your proof of purchase. If a problem should arise, contact the Dealer from which you purchased the coil. If it cannot be resolved there, contact Arizona Outback via email or phone during our normal business hours. Repairs or replacements covered by warranty will be free of charge; however the customer is responsible for shipping costs to Arizona Outback for repair or replacement. If you should have any questions regarding the Warranty Policy, please do not hesitate to contact your Dealer. Thank you again for choosing Nugget Finder - the Leader in Search Coil Technology!
