12 x 15 Inch DD Search Coil in Pure Copper
The DD version of the 12 x 15 inch elliptical coil, wound in pure copper. Copper resists corrosion and conducts well, which is what holds sensitivity over a long service life, and the DD winding is what makes the coil usable on mineralised ground where a mono coil struggles.
Key benefits
- DD winding handles mineralised and trashy ground
- Pure copper winding resists corrosion and conducts efficiently
- 12 x 15 inch elliptical form for coverage without excess width
- Sensitive to small amounts of precious metal
- Part of a coil range including water, ground-level and concrete types
Problems it solves
- Mono coils produce false signals on mineralised soil
- Corroded windings lose sensitivity over time
- Round coils are too wide for some ground
- Small gold targets are missed by less sensitive coils
Who it is for
- Prospectors working mineralised ground
- Detectorists wanting an elliptical coil for constrained sites
- Buyers who want the winding material stated
Application scenarios
- Detecting gold, silver and other precious metals
- Searching gold-bearing ore ground
- Mineralised soil where a mono coil gives false signals
- General detecting on mixed ground
Technical features
- DD coil configuration
- Pure copper winding
- Elliptical 12 x 15 inch form

Customisation options
- Related coil types available for water detecting, ground-level detecting and detecting in concrete
Compared with other models in the range
The mono version of this size gives more raw depth on clean ground. This DD version is the one for mineralised soil and sites with a lot of junk metal, where a mono coil cannot be run at useful sensitivity at all.
Use guide
- Confirm connector and impedance suit your detector before ordering
- Use DD configuration where the ground is mineralised or trashy
- Overlap sweeps by about a third of the coil width
- Ask about the water, ground-level and concrete coil types if the application differs

12 x 15 Inch DD Search Coil in Pure Copper FAQ
What is it wound with
Pure copper, which resists corrosion and conducts efficiently.
Why DD rather than mono
DD handles mineralised and trashy ground; mono gives more depth on clean open ground.
What size is it
12 x 15 inches, elliptical.
Are coils available for other applications
Yes, coils for water detecting, near ground level and in concrete are also offered.
Will it fit my detector
Send us your detector model on WhatsApp and we will confirm connector and impedance.
Can you quote wholesale
Yes. Send the sizes and quantities on WhatsApp.
