Easy-to-use, waterproof detector with notch discrimination, three audio tones, and a target mode

If you’ve ever struggled with using a more advanced metal detector and aren’t sure how to know what the detector is finding before you dig up an item, this is a great metal detector for you. The Treasure Cove TC-3020 Fortune Finder uses three audio tones that categorize a variety of metals and items, and the notch discrimination allows you to eliminate trash from your hunt completely. Take a look at this article to learn more about what makes this a useful metal detector, and also what makes it problematic.

Notch discrimination

When you’re hunting, more often than not you’ll find a lot of junk metal. Items like soda cans, nails, scrap metal, and aluminum siding set off the metal detector and you’ll build a pile of junk before you find anything good. However, when you use the TC-3020’s notch discrimination, you can easily eliminate all this junk from your detector’s range so it will only alert you when something good is detected. You can eliminate all metals except one to find something really specific, or keep the field relatively open so you can have experience just finding something.

Target mode

Finding an item is exciting. However, it can be difficult to pinpoint exactly where it is, and you often have to dig a lot of holes to finally discover it. By using the metal detector’s Target mode, you can save a lot of time and zero in on the exact location of your item. Not all metal detectors have this feature, and you often have to buy a separate handheld pinpointer that costs you more money. With the feature built right in, the Treasure Cove TC-3020 boasts a very high accuracy.

Three audio tones

Many metal detectors just use one tone to let you know it has found something. With this metal detector, you will hear one of three tones. Depending on how you’ve set the notch discrimination, you will hear a low tone for things like nickels and nails, a medium tone for gold, copper, and zinc, and a high one for brass or silver. By just hearing these cues, you’ll know exactly how valuable something might be and if it’s worth digging up.


Very comfortable to use

Many treasure hunts can last for hours, so you want a metal detector that is comfortable to use. The Treasure Cove is designed for both righties and lefties, so no matter what hand is dominant, the metal detector is comfy. It’s also very lightweight, so you won’t get tired or sore. The handle also adjusts so you can find the perfect length for your height.

Hunt in mud or water

Because of the waterproof coil, you can hunt in a lot of places. Whether you’re looking in a muddy swamp for items people have lost over the years or in saltwater, the coil will never be damaged.


One of the TC-3020 Fortune Finder’s cooler strengths is the fact it comes with accessories. In addition to the actual metal detector, you get headphones, a carrying case, and a sand-sifting scoop. These are all items you’d have to buy separately if they weren’t included, so you save some cash and have a complete treasure-hunting kit right at your fingertips.


False signals

A common complaint with all metal detectors is that they can give off false signals. Because the audio tones are categorized by metal type, it might get confused if an item contains more than one metal and send off the wrong signal. If you’re around saltwater or ground with a lot of minerals, the detector can also get a bit wacky. To remedy this, master the settings and notch discrimination to get an accurate reading as possible.

Overall Review

The Treasure Cove TC-3020 Fortune Finder Platinum digital metal detector is an affordable detector with a lot of settings that set it above “toy” detectors, like notch discrimination and the ability to work in rougher terrain. You also get a pinpointer, easy-to-understand audio cues, and a full set of tools to make your treasure hunt fun, accurate, and fruitful.
