Minelab Commander Search Coils   

15" x 12" Semi-Elliptical Double D Search Coil - 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. List Price $523.00; Sale Price $374.00 - Works on SD, GP, or GPX	Minelab 15" x 12" DD Commander Coil - $374.00
15" x 12" Semi-Elliptical Monoloop Search Coil - On larger nuggets this coil has better depth than the 11" Monoloop 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" monoloop. 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.                List Price $512.00 Sale Price $366.00 - Works on SD, GP, or GPX	Minelab 15" x 12" Mono Commander Coil - $366.00
10" x 5" Elliptical Double D Search Coil - 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. List Price $314.00; Sale Price $224.00 - Works on SD, GP, or GPX	Minelab 10" x 5" DD Commander Coil - $224.00
8" Round Monoloop Search Coil - 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 detecti g in heavy vegetation. List Price $314.00; Sale Price $224.00 - Works on SD, GP, or GPX	Minelab 8" Round Mono Commander Coil - $224.00
11" Round Monoloop Search Coil - A lighter, more sensitive and deeper seeking coil compared to its Double D brother, the 11" Monoloop is a brilliant coil for almost any situation. The 2nd most sensitive Commander monoloop, it is also one of the most stable monoloop coils available and will provide a smooth threshold in most soil types. List Price $376.00; Sale Price $269.00	Minelab 11" Round Mono Commander Coil - $269.00
18" Round Monoloop Search Coil - 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. List Price $617.00; Sale Price $441.00	Minelab 18" Round Mono Commander Coil - $441.00
18" Double D Search Coil - A serious coil for the serious operator! The 18" DD punches deep through heavy mineralization, while running smooth to allow you to hear those mellow, deep nugget responses. List Price $617.00; Sale Price $441.00	Minelab 18" Round DD Commander Coil - $441.00

Minelab Commander 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 right coil for the right job.

 

 

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.

• 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 Monoloop 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 Monoloop coil has a detection field that is typically cone shaped, which requires overlapping of sweeps to ensure thorough ground coverage.

Gold Through Technology

In designing the range of Commander coils, Minelab's Product Development Department used the latest in computer imaging programs to create 3D maps of the performance and search pattern coverage of each of the coils. Shown below are a couple of typical mapping diagrams quite clearly demonstrating the blade like search pattern of a Double D coil and the cone shaped pattern of a Monoloop coil.

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 monoloop coils and they allow the use of the Coil switch found on the GP series. Pinpointing is done along the center of the coil. Monoloop 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 Monoloop 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 Monoloop coil has a detection field that is typically cone shaped, which requires overlapping of sweeps to ensure thorough ground coverage.
