Minelab Commander Search Coils

A completely new line of premium high performance coils - exclusively designed for Minelab GP, GPX and SD Series 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.

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.
