Double D vs Concentric Coils: Which One is Right for Your Metal Detecting Needs?
When it comes to metal detecting, the type of coil you use can make a significant difference in the results you get. Two common types of coils are double D and concentric coils. In this article, we will compare the two and help you determine which one is right for you.
Double D Coil:
A Double D (DD) coil has two overlapping wire loops shaped like a “D,” hence the name. The DD coil sends out two signals simultaneously, which helps with target separation and depth detection. These coils work well in mineralized soil conditions since they reduce ground interference. They also cover more ground per sweep than concentric coils due to their shape.
Concentric Coil:
A concentric coil consists of two circles that are placed one inside another. This design means that the signal transmitted from this type of coil makes a cone-shaped pattern as it penetrates into the ground, making it useful for discriminating targets close together or on top of each other. Concentric coils provide excellent target pinpointing but have less depth penetration compared to DD coils.
So which one should you choose?
If your main goal is deep seeking and coverage, then go for a Double D coil since they can detect deeper targets and cover more ground per sweep than Concentric Coils. However, if your primary focus is on greater accuracy based on good discrimination properties along with precise location spotting abilities, then Concentric Coils would be your best bet.
It’s essential to note that both types of coils have their strengths and weaknesses depending on what kind of metal detecting job needs doing – there’s no ultimate winner between them! It all boils down to personal preference and experience.
In conclusion, choosing between Double D vs Concentric Coil depends entirely upon what kind of metal detecting task lies ahead; whether deep seeking coverage or accurate discrimination-based detections are required determines which type of detector will be most useful for success at finding what treasures may lay beneath our feet.
