With funding from the success of the sales of the world’s first Pulse Induction detector with microprocessing control, Detech opened a new division producing accessory coils for leading brands of metal detectors. This led to the development of innovative search coils that offer many advantages over standard coils.
Detech coils come in several common sizes, including the smaller 8 x 6” SEF, 4.5 x 7” SED, 10 x 5” SEF, 13” Ultimate, 15” Ultimate, 7” Ultimate, 12” x 10”, 15” x 12”, 18” x 15” SEF Butterfly coils . Detech even has an extensive offering of coils for Minelab detectors. There are coils for Minelab E-TRAC, Safari, Explorer, Sovereign, GPX, GP, and SD Series Gold Detectors in sizes as small as a 6” mono loop, all the way up the world’s largest 32” concentric coil for GPX, GP, and SD Series Gold Detectors.
Determining what size coil will be best for you will depend on what you are searching for and where you will be searching. Bigger can be better, but not always. Larger coils, in general, have wider and deeper search areas. If you need to cover a large area or are searching for deeper targets, a larger coil may be the way to go. However, bigger isn’t always better. Smaller coils may be a better choice for working in tight spaces, especially those with a lot of brush. Their more concentrated search area gives them better target separation and pinpointing and works well in areas with a lot of metallic trash or where there are multiple targets in a small space. They are also more effective in finding the tiniest of targets.
