Treasure Hunting with Metal Detectors

Whether it is the anticipation of finding pirate treasure or the hope of finding precious lost items, metal detectors are in high demand this year. There are many different types of metal detectors available which can make selection a bit daunting so I will give a little rundown of the selection at our Vaughan Ontario Bass Pro Shops location. We carry the First Texas Brand of Bounty Hunter and Teknetics metal detectors. First Texas has built up a solid reputation over the past thirty years which helps provide peace of mind with your metal detector investment. In the Bounty Hunter line we carry the Junior, Challenger, Lone Star and the Camo LS models. In the Teknetics line we offer the Delta 4000 and the Gamma 6000.

Before I get into the variety of models I will give a brief explanation on the mechanics and some terminology.

Metal detectors are basically made up of a coil, control box and power supply. An electric current travels through the coil which sends kilohertz frequency signals into the ground. If there isn’t any metal your detector will remain silent, otherwise it will produce various sounds that alert you to metal interference. Each metal produces a different frequency. You can control the frequency to allow you to focus on a specific metal. The lower the frequency the deeper you can go, but you may miss a small object or a metal that is a higher frequency (like gold). That being said, frequency is only one of the factors that determine depth and sensitivity.

The detectors ability to determine the type of metal so it only identifies the type of metal you are looking for (to save you digging up all those bottle caps and tin cans). There are different types of discrimination; variable, notch filler and tone identification which provide different formats of metal identification. However, having said this, it is important to understand that there are different factors that can change the discrimination consistency such as metal purity and size/depth of the target.

Coil Size
The coil size is important when looking at depth, sensitivity and control. A smaller coil is lighter weight, more sensitive and easier to control but does not provide the depth abilities of a larger coil. Coils come in three main shapes, solid round, elliptical and open web. While the solid round is the most common shape, the elliptical is used in heavy bush or stony areas and the open web is used in water (wading or underwater detection).  

For those who are just starting out in the world of treasure hunting, a more basic model like the junior or Challenger would be the best way to go. The Junior is designed for kids but still functions like a standard metal detector. It can find coin sized objects buried up to five inches or larger metal items up to three feet. It has a noise variance that allows for identification of a metal target and weighs in at two pounds for easy handling. The Challenger is a beginner’s level metal detector but it still provides substantial detection through dirt, rock, wood and mud. Some of the features are a dual tone discrimination mode, seven inch submersible search coil and two modes of operation. Moving into the advanced level we have the Lone Star. This digital metal detector has three modes of operation, touch pad selection and three-tone audio discrimination as well as a five section target identification mode. This more sensitive model allows for the automatic elimination of unwanted objects which saves you time and energy in your search of valuable coins, jewelery or other treasures.

For serious treasure hunters we have the Camo LS, the Delta 4000 and the Gamma 6000. The Camo LS has four mode operations, pinpoint target control and four level iron discrimination. There are two distinct systems, no motion mode and auto notch discrimination which allows you more sensitivity to separate the treasure from the junk. With numeric target identification, discrimination and notch systems with three tones and three operation modes, the digital Delta 4000 has high sensitivity.  It also has a five level running depth readout and preset ground balance to deal with various soil conditions. Finally, we have the top detector in our repertoire, the Gamma 6000. This detector has several fantastic features including eighty levels of discrimination adjustment, mineralization readout and four-tone selection.  

All of the metal detectors we carry run on 9V batteries and have one or five year manufacturer warranties. Some of the detectors have waterproof coils which, allows them to be submerged which allows for more treasure hunting opportunities. The manuals are very precise and informative which will allow you to utilize your detector to its utmost capabilities. To help you out we also carry two accessories for the metal detectors, the carry bag and the headphones. The headphones will help with soft sounds that you may miss during a sweep.

Starting Your Hunt
There are lots of places to start your hunt; the beach, a park or even your own backyard. Just make sure to ask permission if on private property or check out regulations in public places and respectfully leave the area as you found it. When you are out treasure hunting it is important to remember to be patient, methodical and attentive to the different sounds that your detector makes. But most importantly, go out and have fun with it. At first you may only find tin cans but you just never know when you’ll unearth a goldmine. 

And it makes a really neat unique gift!

Happy treasure hunting!
