Series Accessory Search Coils

A completely NEW line of PREMIUM high performance coils- exclusively designed for MINELAB GP and SD Series Gold detectors!

Precision designed, engineered, built and tested by Minelab

The technology used in Minelab’s gold detectors has become more and more advanced with time. Ensuring that our coils have kept pace with those advances in technology has been equally important to Minelab, so that our customers can be assured that their coils are the best match for their detector investment. Minelab Commander series coils have been designed by the Minelab team of scientists & engineers, specifically to match the requirements of Minelab technology and to give optimum performance.

All the Commander series coils are made using the very best quality components like gold plated plugs, low-noise shielded cable and multi-strand Litz wire. Litz wire, is made of numerous, very fine individually insulated strands. 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. This translates into a more powerful, energy efficient coil for its size.

Commander coils are well made, robust coils, designed to cope with the rugged conditions of the gold fields. Designed to get the most out of your GP series detector, the following coils will also enhance the performance of your SD series machine. Sure there are some higher priced after market coils available as well, but these coils are from Minelab and in many cases outperformed the competition!

I use these coils myself and highly recommend them for use with your Minelab SD or GP series detector for added stability and depth the after market coils can not deliver especially with the GPX models. These coils are specifially designed to give you the depth and stability the newer GPX models are designed to deliver.

  • Coil Size & Depth - A larger coil will typically find targets hidden deeper in the ground, but they can be less sensitive to smaller targets. A smaller coil is typically more sensitive to small targets, but does not go as deep as a larger coil.
  • Mineralization - A Mono loop coil will often have improved performance over a Double D coil but can be more difficult to ground balance and therefore possibly more noisy. A Double D coil is often more stable in heavily mineralized areas.
  • Terrain & Vegetation - A larger coil requires more open ground whereas a smaller coil can be easier to guide in tight bush or rough terrain. Obviously a smaller coil is also lighter weight than a larger coil.
  • Discrimination - In areas where discrimination is required, a Double D coil will provide a more accurate ID. In high trash concentrations, a smaller coil is preferable.
  • Search Pattern - A Double D coil will typically provide a 'blade-like' detection pattern from the toe to the heel of the coil, which gives excellent ground coverage. A Mono loop coil has a detection field that is typically cone shaped, which requires overlapping of sweeps to ensure thorough ground coverage.

    • Available NOW from Minelab in these sizes and configurations:

  • 8" Round Mono loop - The most sensitive of the Commanders, the 8" round provides the best depth on sub-gram nuggets in light to moderately mineralized soils. A popular coil for use on old diggings, it is also a great coil for detecting in heavy vegetation. This is one of my personal favorites for the GPX series!

  • 10" x 5" Elliptical Double D - This is the coil that every prospector should carry because of its endless versatility. Great in thick scrub, heavy mineralization and high trash; it has superb sensitivity and surprising depth for such a small coil. It is also great for pinpointing deep targets found with one of the larger coils and is extremely stable in all soils. Very good for hunting dry washes with heavy black sand deposits that can give a mono loop fits.

  • 11" Round Mono loop - A lighter, more sensitive and deeper seeking coil compared to its Double D brother, the 11" Mono loop is a brilliant coil for almost any situation. The 2nd most sensitive Commander mono loop, it is also one of the most stable mono loop coils available and will provide a smooth threshold in most soil types.

  • 11" Round DD - This is the same as the stock SD and GP Coils, but still made with the Commander series quality and reliability. A great coil for "hot soils" while still getting great depth and sensitivity. A DD coil can be a "Must" under some conditions and when using "Cansel or Discriminate" modes which do not work with a mono loop coil.

    Your Price $288.95

  • 15" x 12" Semi-Elliptical Mono loop - On larger nuggets this coil has better depth than the 11" Mono loop and the 15x12" DD, and it is very sensitive for its size. It is great for searching open areas for new patches and when seeking out deeper nuggets in areas that are too vegetated to allow effective use of the 18" mono loop. It is an extremely stable coil which runs smooth in all but the worst soil conditions. This coil will become a favorite for many operators and is one I use much of the time in the Arizona Deserts.

  • 15" x 12" Semi-Elliptical Double D - Greater depth and more ground coverage than the 11" DD, It provides stable operation in all soils. This is a great coil for all-round use in highly variable soils and a lighter, more maneuverable alternative to the 18" DD when seeking out large nuggets in heavy mineralization. Its semi-elliptical design provides impressive sensitivity for its size allowing the operator to still find those small targets missed with other large coils.

  • 18" Round Mono loop - Superb depth and high sensitivity in low to medium mineralization. This coil will find targets in heavily worked areas where other operators have given up and there is good depth of soil. The larger coils are made for open areas where large rocks and shrubs are not a problem preventing you from keeping the coil at proper height for efficient hunting. Under the right conditions this coil gives the operator a huge depth and ground coverage advantage.

  • 18" Round DD - Superb depth and high sensitivity in high mineralization. This coil will find targets in heavily worked areas where other operators have given up and will run smoother than the mono loop in the same ground. The 18 inch Commander coil is made especially for hunting wide open deep ground where you know there is big gold at depths not obtainable with smaller coils and being a DD it will run quiet under the worst ground conditions.

    • What's the Difference? Double D coils provide a blade-like detection pattern for accurate ground coverage. They handle heavy and variable mineralization better than mono loop coils and they allow the use of the Coil switch found on the GP series. Pinpointing is done along the center of the coil. Mono loop coils are more sensitive and deeper seeking than an equivalent sized DD, but can become erratic in very mineralized soils. The detection field is cone shaped, so it requires overlapping sweeps to ensure thorough ground coverage at maximum depth. Very sensitive around the outer rim, the coil can be tilted on edge when pinpointing tiny targets.

    Choosing the Right Coil for the Job

    There are five main things that you should consider when deciding which coil is best for your terrain and target.

  • Coil Size & Depth – A larger coil will typically find targets hidden deeper in the ground, but they can be less sensitive to smaller targets. A smaller coil is typically more sensitive to small targets, but does not go as deep as a larger coil.
  • Mineralization - A Mono loop coil will often have improved performance over a Double D coil but can be more difficult to ground balance and therefore possibly more noisy. A Double D coil is often more stable in heavily mineralized areas.
  • Terrain & Vegetation – A larger coil requires more open ground whereas a smaller coil can be easier to guide in tight bush or rough terrain. Obviously a smaller coil is also lighter weight than a larger coil.
  • Discrimination – In areas where discrimination is required, a Double D coil will provide a more accurate ID. In high trash concentrations, a smaller coil is preferable.
  • Search Pattern – A Double D coil will typically provide a ‘blade-like’ detection pattern from the toe to the heel of the coil, which gives excellent ground coverage. A Mono loop coil has a detection field that is typically cone shaped, which requires overlapping of sweeps to ensure thorough ground coverage.
