Unveiling the Secrets of Metal Detecting Search Coils
When it comes to metal detecting, the search coil is a critical component of your equipment. The search coil, also known as a search head or loop, is the part of the metal detector that emits electromagnetic fields to detect metal targets underground. There are various types of search coils available on the market, each with its own unique features and benefits. In this spotlight post, we will explore some of the most common types of search coils used by metal detector enthusiasts.
1. Concentric Search Coils:
Concentric search coils have two wire coils arranged concentrically – one inside the other. The outer coil transmits electromagnetic signals while the inner coil receives them. This design allows for more accurate target identification and better discrimination between different types of metals. Concentric coils are excellent for pinpointing targets in trashy areas or highly mineralized soil due to their precise detection capabilities.
2. Double-D Search Coils:
Double-D (DD) search coils consist of two D-shaped wire windings positioned back-to-back without overlapping. This design creates a specific detection field shape that provides excellent ground coverage and depth detection capabilities. DD coils are popular among treasure hunters for their superior performance in mineralized soils and highly littered areas.
3. Elliptical Search Coils:
Elliptical search coils have an oval-shaped design that offers improved maneuverability and access to tight spaces compared to standard round coils. These coils are ideal for detecting in uneven terrains such as rocky surfaces or thick brush where a larger round coil may be cumbersome to use effectively.
4. Mono Search Coils:
Mono (monoloop) search coils consist of a single wire winding that serves both transmission and reception functions simultaneously. Mono coils are known for their high sensitivity to small and deep targets, making them popular among relic hunters and prospectors searching for tiny gold nuggets or artifacts buried at significant depths.
5. Super Deep Search Coils:
Super deep search coils are specialized large-size mono loops designed specifically for maximizing depth penetration when searching for deeply buried targets like caches or antique relics buried beneath layers of soil over time periods.
6 Waterproof Search Coils
Waterproof search coils are built with waterproof materials such as epoxy resin or polyurethane coatings to protect against water damage when detecting on wet sand beaches, shallow waters, riverbanks, lakeshores, etc., where regular non-waterproof coiled would fail due corrosion caused by exposure moisture elements like saltwater which can cause rusting leading malfunctioning device shortening lifespan overall operation efficiency reducing significantly
7 Coil Size Variations
