How the Shape of Your Metal Detector’s Search Coil Effects Your Treasure Hunting Success

Search Coils

Owning the right type of search coil that matches your metal detector will make it easier when searching for treasure.

The shape of the search coil you use on any of your metal detectors will change the capabilities of your machine and, as a result, having several different types on hand will really enhance your treasure hunting experience. In fact, many metal detectorists feel that you can transform your metal detector into an entirely new machine simply by selecting different size and shape search coils as opposed to actually buying a whole new machine! There are two parts of a search coil to talk about when discussing their shapes. First is the shape of the search coil itself. The search coil itself will be either round or elliptical – most will be round. More important than this though is the internal construction. The way the wires are attached to the coil internally will take one of the three following forms – Concentric, Double D, or Coaxial – each giving your metal detector different capabilities. Let’s discuss each of these search coil designs, their benefits, drawbacks, and more.

Concentric

Concentric circle search coils are probably the most popular design of search coil for metal detectors today. Most commonly used for finding smaller targets like gold, jewelry, coins, and relics that are generally found near the surface concentric coils are also excellent at target discrimination and pinpointing. They’re drawback? Concentric coils are easily compromised in heavily mineralized soils.

Double D

A Double D search coil is designed in the shape of two capitol letter “Ds” hence it’s name! Double D metal detecting search coils are reliable in heavily mineralized soils, like what you run into at the beach for example, and cover more ground in one sweep than other types of coils. They’re not as good at pinpointing nor as adept at target discrimination; although many of the newer DD coils being made today are.

Coaxial

Coaxial coils are probably the least popular search coil design type and are rarely found on metal detectors made today. While it’s detection depth is usually lower, the coaxial search coils are the best type of coil to use when you need to minimize interference from utility wires or other metal detectors. Coaxical coils are also great at pinpointing and discrimination even in areas with very heavy trash.

All shapes are generally available in all sizes (extra small/mini, small, medium, and large) and vice versa. Whatever size and shape search coil you buy for your metal detector though, be sure you’re purchasing quality search coils that are compatible with your metal detector in order to avoid violating any warranties or, worse, causing your machine to malfunction. You’ll also need to consider the type of metal detector you’re using, the frequency it operates on, and, as we mentioned, where you’re working, and what you’re hunting for. From there though you’ll easily be able to buy all the right shapes and sizes of search coils to find treasure wherever you’re metal detecting.

Best Places to Treasure Hunt with Your Metal Detector

Treasure Hunting Tips

When treasure hunting, two of the most important things are knowing where to search and having the right metal detector to help you.

When you’re eager to find lost coins, jewelry, relics and treasure—the first question in your mind is “where should I hunt?” Obvious spots are probably right under your nose and it’s prudent to get suggestions from veteran treasure hunters. After all, they’ve been experimenting with metal detectors for years and know where to find success. If you’re a fan of the National Geographic TV show Diggers, you’ve heard KG and Ringy talk about finding ‘nectar.’ This refers to the millions of dollars in coins and artifacts that sit just below our feet. So, with metal detector in hand—you’re probably ready to find some valuable nectar yourself. Here are suggestions from the experts for potentially successful metal detecting spots:

Public Parks & Recreation areas – search around drinking fountains, benches, picnic tables, walkways, entertainment platforms & pavilions. When metal detecting on private property you need to get permission from the land owner. With that said, amusement parks, fairgrounds, carnival & circus sites can be great spots to search. Any areas where lots of people have gathered over the years such as sports stadiums are great sites. You can check around the buildings, in the parking lot and even beneath stadium seats!

When metal detecting, it is important to learn about the local and national laws before setting out on your hunt. National treasure hunting organizations and local treasure hunting clubs can provide information on the current laws, rules and regulations. Other top sites to explore include:

  • – Beach swimming areas and public pools – especially concession and play areas
  • – Swimming pools and swimming holes
  • – Fishing piers, boat ramps and landings
  • – Horse and hiking trails, campgrounds and children’s camps
  • – Schools and colleges – around playground equipment, water fountains and doors or where people wait in line
  • – Tourist and rest stops lookouts and scenic spots
  • – Wishing wells and fountains- search below ponds or water where people pitch coins
  • – Service stations – don’t forget older and abandoned gas stations
  • – Old drive-in theater locations – search around ticket windows and concession areas
  • – Motels and hotels- current and former locations
  • – Old buildings and abandoned homes – doorways, next to porches and steps, near mailboxes and along all walkways and paths
  • – Your own yard – you will be surprised what you can recover from your own backyard!

These are just a few ideas for treasure hunting locations. You can also visit your local library and do a little research on local history. Perhaps you’ll stumble across information about rumored treasure caches or the sites of old buildings. This may provide you with a list of spots that could yield quantities of old and valuable treasure.
