Minelab 15 x 12 inch Semi-Elliptical Double-D (DD) Commander Coil for GPX, GP & SD Detectors

Yes, the 15" x 12" Commander is a Double-D coil, which means it fully supports Iron Reject and RX Cancel features on GPX series detectors. Iron Reject helps you filter ferrous trash like nails and iron fragments in relic sites without losing depth on non-ferrous targets, and RX Cancel reduces electromagnetic interference from power lines or other detectors operating nearby. These features are not available with Monoloop coils, so the Double-D winding is the right choice for detectorists working iron-heavy contexts. For additional guidance on optimizing Iron Reject settings for your soil type, check our practical detecting tips.

The 15" x 12" Commander coil is compatible with GPX 5000, GPX 4800, GPX 4500, GPX 4000, GP 3500, GP 3000, GP Extreme, and the SD series including SD 2200v2, SD 2100v2, SD 2200d, SD 2100e, SD 2100, and SD 2000 detectors. This coil uses Minelab's MPS technology connector and is not compatible with Equinox, X-Terra, or Vanquish series detectors. If you own a GPX or older GP/SD model and need wider ground coverage for relic hunting or cache searching, this coil pairs directly with your detector's existing cable and control box.

The Commander coil measures 15 inches by 12 inches in a semi-elliptical footprint. Minelab does not publish the exact weight for this coil in their current specifications, but the semi-elliptical shape is lighter and more maneuverable than a full 15-inch round coil of equivalent coverage. The coil ships with a protective cover and mounting hardware, and the cable uses gold-plated plugs with low-noise shielding for stable signal transmission in mineralized ground.

The 15" x 12" Commander coil is water resistant, not fully submersible. You can use it in light rain and damp grass, but do not submerge the coil or cable in water. Check your GPX detector's specifications for water-resistance limits before exposing the control box or cable connections to moisture. For wet-sand beach hunting or stream wading where full submersion is required, consider a fully waterproof detector platform like the Equinox or Manticore series instead.

The package includes the 15" x 12" Commander Double-D coil, a fitted protective coil cover, and mounting hardware for attaching the coil to your GPX, GP, or SD series detector. The coil cover protects the winding from abrasion when you're working rocky ground or brushy terrain, and the hardware ensures a secure fit to your detector's lower shaft. The coil cable is permanently attached and terminates in a gold-plated plug compatible with MPS-technology detectors.

The semi-elliptical 15" x 12" footprint covers nearly as much ground per swing as a full 15-inch round coil but is lighter and easier to control in uneven terrain. The narrower front-to-back dimension (12 inches) reduces the coil's moment of inertia, so you can swing it for longer sessions without arm fatigue, and the shape fits between obstacles like fence posts and tree roots more easily than a round coil. Detectorists working open fields and large relic sites prefer this geometry because it balances coverage with maneuverability.

Minelab Commander coils use multi-strand Litz wire, which has higher surface area than standard wire and delivers greater signal transmission ability. This results in more powerful and sensitive coil performance, especially at depth in mineralized soil. The cable is low-noise shielded to reduce electromagnetic interference, and the connector uses gold-plated plugs for corrosion resistance and stable electrical contact. This construction is part of Minelab's MPS technology design, engineered to meet the precise requirements of GPX and GP series pulse-induction detectors.

The 15" x 12" Commander is primarily a deep-seeking relic and cache coil, not a gold prospecting coil. Its large footprint sacrifices sensitivity to small nuggets in favor of deeper penetration on larger targets like coins, relics, and cache containers. Smaller coils may offer better sensitivity to small nuggets and tighter target separation in goldfield trash. If you're hunting nuggets in known gold ground, consider a smaller metal detector search coil designed for fine-gold sensitivity rather than this wide-coverage relic coil.

The 15" x 12" Commander coil is manufactured by Minelab using high-quality components including gold-plated plugs, low-noise shielded cable, and multi-strand Litz wire for robust performance in rugged goldfield conditions. Commander coils are designed by Minelab's team of scientists and engineers to meet the precise requirements of MPS technology and deliver optimum performance on GPX, GP, and SD series detectors.
