11 Inch DD Search Coil with Strong Structure
An 11 inch DD coil offered in three sensitivity builds rather than one: standard for general work, reduced for low-level conditions, and ultra-sensitive where extra response is needed. It detects aluminium, steel, copper, iron and other metals, in a structure specified to hold up under daily field use.
Key benefits
- Three sensitivity versions: standard, reduced and ultra-sensitive
- 11 inch DD size, light enough to sweep all day
- Detects aluminium, steel, copper, iron and more
- Strong structure for the rigours of everyday use
- DD winding suits mineralised and trashy ground
Problems it solves
- One sensitivity build does not suit every ground condition
- Large coils are unusable in confined or junk-filled sites
- Standard coils break under daily digging use
- Mono coils cannot be run at useful sensitivity in mineralised soil
Who it is for
- Detectorists who want to match coil sensitivity to their ground
- Users searching confined or trashy sites
- Buyers replacing coils that keep failing
Application scenarios
- General ground detecting on mixed soil
- Low-level conditions where reduced sensitivity is wanted
- Sites needing maximum response from a small coil
- Replacing a stock coil with a tougher one
Technical features
- DD coil configuration
- Three sensitivity variants
- Reinforced structure
- Adjustable detection range

Customisation options
- Three sensitivity versions: standard, reduced and ultra-sensitive
Compared with other models in the range
The 11 inch mono coil in camouflage is the lighter, simpler alternative for clean ground. This DD version handles mineralised and trashy sites and is the only coil in the range offered in three separate sensitivity builds.
Use guide
- Choose the sensitivity version that matches your ground before ordering
- Confirm the connector and impedance suit your detector
- Use the standard version for general work and the ultra-sensitive where response matters most
- Fall back to the reduced version where ground noise is high

Why choose DD at this size
DD handles mineralised and trashy ground, which is where an 11 inch coil is most often used.
Will it fit my detector
Send your detector model on WhatsApp and we will confirm the connector and impedance.
Is it strong enough for daily use
It uses a strong structure specified for the rigours of everyday use.
Which version should I order
