Overview of the Features

If you are someone who does not wish to struggle with a metal detector and need something simple, easy to use, and straightforward, then the Treasure Cove TC-3020 Metal Detector is what you need.

This detector uses three audio tones that categorize a variety of metals and other items. Its impressive discrimination also does a great job of eliminating trash from your hunt.

  • Discrimination

When you are out detecting, you are most likely going to find a lot of junk metal, like scrap metal, soda cans, nails, and more. This can set off the detector, and you will end up digging out a pile of junk.

With the Treasure Cove TC-3020 Metal Detector, you won’t have to suffer from this. Its discrimination will easily eliminate all the junk from the range of your detector, which means that it will only alert you when you are detecting something worthwhile.

With this, you will be able to eliminate all metal other than the specific one that you are looking for. Else, you can simply keep the field open so that you can experience metal detecting.

  • Target Mode

When you find an item on your detector, it can be very exciting. Yet, it is still difficult to exactly pinpoint where the item may be and, in some cases, you will have to do a ton of digging to actually discover the item.

Thankfully, with the Treasure Cove TC-3020 Metal Detector’s target mode, you can save yourself a lot of time and simply zero in on the exact location of your item.

This feature is something that you will not find in every metal detector. In fact, you will have to buy a separate handheld pinpointer that will end up costing you more money to enjoy such a feature. Having this built into this metal detector boasts a very high accuracy.

  • Three Audio Tones

You will often find that many metal detectors on the market tend to make use of just one tone to alert you that it has detected an item. With the Treasure Cove TC-3020 Metal Detector, you can hear one of three tones.

Based on how you have set the discrimination, you will be able to hear a lower tone for items such as nails and nickels, a medium tone for items such as zinc, copper, and gold, and a high tone for items like silver and brass.

By just hearing these specific tones, you will be able to know exactly how valuable the item might be and whether or not it is worth the effort to dig it up.

  • Accessories

One of the best things about this metal detector is that it comes with a ton of accessories to further make metal detecting easy and fun.

Along with the metal detector, you also get a carry case, a sand-sifting scoop, and a pair of padded headphones. These are items that you would have to buy separately and pay additional money for, but with this, you end up saving some cash and have a complete metal detecting kit with your single purchase.
