18 Inch Mono Search Coil with 2 Ohm Impedance
An 18 inch mono coil wound in copper with a 2 ohm impedance, for detecting coins, jewellery and other metallic objects. The 2 ohm figure is the one that matters when matching a coil to a detector circuit, because it determines whether the coil will tune correctly with the machine you already have.
Key benefits
- 2 ohm impedance stated, so it can be matched to a detector circuit
- Copper winding for consistent sensitivity
- 18 inch diameter balances coverage against weight
- Switch control allows power to be cut when not needed
- Supplied with the accessories needed to fit it
Problems it solves
- Coils without a stated impedance cannot be matched to a circuit
- A mismatched coil will not tune correctly with the detector
- Original coils are often unavailable as spare parts
- Leaving the coil powered when not in use drains the battery
Who it is for
- Users matching a coil to a specific detector circuit
- Repairers replacing a damaged coil
- Buyers who need the impedance figure before ordering
Application scenarios
- Detecting coins, jewellery and metallic objects
- Replacing a coil on an existing detector circuit
- Building or repairing a detector circuit
- General purpose ground searching
Technical features
- Copper construction
- 2 ohm impedance
- Switch controlling current flow through the coil
- Switching between different coils where required

Compared with other models in the range
The 25 inch mono coil covers more ground per sweep; the 22 inch DD handles mineralised soil better. The 18 inch mono is the mid-size option, and it is the one in this range with a published 2 ohm impedance for circuit matching.
Use guide
- Confirm your detector circuit is matched to a 2 ohm coil before ordering
- Fit the connector and check the coil tunes correctly with the machine
- Use the switch to cut current when the coil is not in use
- Note that no instruction manual is supplied with this item

18 Inch Mono Search Coil with 2 Ohm Impedance FAQ
What impedance is the coil
2 ohm, which is the figure to check against your detector circuit.
What is it wound from
Copper.
Will it fit my detector
Confirm the 2 ohm impedance suits your circuit and send us your detector model on WhatsApp so we can check the connector.
Is an instruction manual included
No. The source specification states no instruction manual or documentation is supplied with this item.
What can it detect
Coins, jewellery and other metallic objects.
How does it compare with the 25 inch mono coil
The 25 inch covers more ground per sweep; the 18 inch is lighter to sweep and publishes its impedance for circuit matching.
