Coiltek 18" Search Coil for Minelab Manticore Review


Minelab Manticore Maximum depth and performance with a MythTek 18 inch coilThe Coiltek MythTek 18" search coil for the Minelab Manticore is a standout piece of equipment, offering impressive size and sensitivity.
First and foremost, the sheer size of this coil is remarkable— it measures a substantial 18 inches (455 mm).

This generous size allows for significant ground coverage with each sweep, making it an excellent choice for those looking to maximise their search efficiency.

Despite its size, the coil does not compromise on sensitivity. It is adept at detecting smaller, shallower targets.
how sensitive is the Manticore Mythtek coil
But note that in areas where there are many targets and the recovery speed has to be increased to a point where depth will be compromised thus defeating the use of the coil for which it designed, But it excels in finding deeper, larger objects. This balance between size and sensitivity makes it a versatile tool for a range of detecting needs.

However, potential users should be aware of the coil's forward-heavy feel. This design aspect means that using a harness is essential for longer detecting sessions to prevent fatigue.
A Tip for making the Mythtek coil to feel more balanced is to use it "back to front" this makes the fulcrum of the coil change position and feel better to swing.
The Coiltek MythTek 18" coil is specialised equipment, best suited for targeting deeper, larger finds rather than everyday use. Nonetheless, as i say it remains quite capable of locating smaller targets as well in the right locations.

This coil is particularly suited for using the lower frequency modes of the Minelab Manticore, such as "All Terrain High Conductors" or "Beach Deep."

These modes enable the low frequency to penetrate deeply into the ground, making it highly effective for uncovering hidden hoards, and deeply buried large items.
When it comes to recovery speed, the Coiltek coil performs better with a lower recovery speed in cleaner ground with fewer targets. This setting allows for maximum depth performance rather than focusing on target separation. Therefore, it's ideal for areas with minimal trash where depth detection is crucial.
It is possible to use on a single frequency but as discussed before, this makes the Multi IQ+ features unused.


using the correct swing speed with the minelab manticore and mythtek 18 inch coilAdditionally, a slower swing speed is recommended when using the Coiltek coil. This careful approach ensures that the coil can accurately process the signals and provide optimal performance in terms of depth and sensitivity.




When using the lower frequency modes, the Minelab Manticore will use more power.

I recommend using the "POWER X" power bank that clips onto the shaft of the Manticore (or other detectors) and will allow for a much longer metal detecting session.




In summary, the Coiltek MythTek 18" search coil for the Minelab Manticore is a specialised yet versatile tool that offers impressive depth and sensitivity. It is particularly well-suited for those seeking deeper and larger targets, though it can still handle smaller finds with ease. Just remember to use a harness for extended detecting sessions due to its weight.
