Entry level – deepest metal detector

Beginners always find it hard to look for the right detector that won’t confuse them when they’ve just picked up the hobby. We’ve got some here that have earned positive credits from many newbies.

Bounty Hunter Discovery 3300 Metal Detector – Best Overall

Bounty Hunter Discovery 3300 Metal Detector
Bounty Hunter Discovery 3300 Metal Detector

  • Long warranty
  • Conduct significant deep searches
  • Can indicate the numeric depth
  • Affordable price point


  • Visual ID sometimes is not accurate

Dollar-for-dollar, there isn’t another detector on the market that has the features and abilities of this one.

At the default setting of sensitivity, we can find coins pretty effortless down to 6 to 7 inch at the Illinois ground where there are not a lot of mineralization.

So, the higher the sensitivity, the deeper you can detect, but also the more susceptible it’s going to be in (EMI Electro Magnetic Interference.) That said, there must be a happy medium there with sensitivity.

The tip we found is in the ground balance which you should conduct manually rather than the presets. As this machine got pinpoint mode, functioning alongside the manual ground balance will get you to detect metals down to 8 inches.

We used to dig a coin at 11 inches deep and a large metal plate at 4 feet. This is a practical approach.

The machine has a straightforward usage which is suitable for all beginners. It has an adjustable height and lightweight that will fit kids also.

Operating Frequency6.6 kHz
Audio Frequency4-tone
Search modesMotion All-Metal, Progressive Discrimination, Notch, and Pinpoint
Ground balancePreset and manual
Search Coil8-inch waterproof
Maximum Search Depth8 inches for coins and 4 feet for big objects
Highlight FeaturesManual ground balance for deeper search

The machine is perfect for people who are new to deep search and skilled seekers with features that are good overall.

Garrett Ace 250 Metal Detector – Best for freshwater hunting


  • The metal filter functions well
  • Great customer support
  • Sensitive unit
  • Lightweight


  • No volume control
  • The machine is relatively mineral sensitive

We will definitely grab this detector for our next beach ground hunting.

The ACE 250 has several modes to search different kinds of metals like. There is a custom mode which you can program and save for the next use. The relic mode accepts everything but iron. At coin mode, it will discriminate out the iron foil and pull-tab area.

With this detector in hand, you can locate coins deeper than inches with 8 sensitivity settings for the best accuracy. Of course, it should not miss the electronic pinpoint mode to support targeting deeply buried objects.

The detector gives different tones to different metal materials. The point is you don’t have to continuously stare down to the ground to avoid neck ache but are still able to identify your target.

We are pretty in love with the eliminate button which will wipe out anything irregular to your goal. This means it can accept or reject notch for more precise search.

The Graphic Target ID cursor is a great plus on this detector that will indicate the probable identity of the objects so you won’t waste time digging the dump.

You can submerge the coil into the water for a freshwater search all day long. But let the liquid away from the electronic box, or it’ll be shot.

Operating Frequency6.5 kHz
Audio Frequency3-tone
Search modesAll-Metal, Discrimination, Notch, Pinpoint, and Custom

  • Entirely waterproof unit
  • Adjustable iron audio great for deep search
  • The high concentrated coil supports deep ground hunt
  • Suitable for treasure hunt day and night

Fisher is a reputable company for no doubt, hence the quality of this detector.

The machine from Fisher lab is a completely waterproof unit that can stand under the rain without the top electronics being bothered. You now have all the freedom to hunt, rain or shine.

One good thing we have noticed is if we were to scroll through the Fe, we could change the tone. The deeper the signal penetrates the soil, the quieter the tone is. If we meant to dig for gold, we could change from VCO to 2 or 3.

What’s good about it is you can manage the possibility of whatever is beeping. As far as you manually adjust, you will get the volume control of the ferrous or non-ferrous target. That will increase the chance of blocking out iron or have it read off very faint for a more valuable object.

The machine can reach up to 10 inches in depth with pinpoint and discrimination modes to search for costly assets like gold and silver. There are 10 sensitive levels to promote the accuracy of the search. But note that how deep it goes depends on the mass of the object.

Operating Frequency7.69 kHz

Search modesAll-Metal, Discrimination, Notch, Pinpoint, and Custom
Ground balanceGROUND-GRAB Computerized Ground Balancing and Manual
Search CoilConcentric Triangulated Elliptical Waterproof

How to choose the deepest metal detector (buying guide)

Deepest Metal Detectors That Punch To The Greatest Depth

The adventure of discovering treasure is so attractive to many curious heads. But shopping for a metal detector is not anything of looking perfunctorily.

So, you have the best detector in hands; it’s time to walk through the criteria needed to buy the most suitable one for you.


It is important to know how much you can spend on a detector. You may not have enough for a multi-purpose machine but want the similar features of acceptable quality.

Also, unless you have the eager to make metal detecting your daily part or else, get one that is not too expensive.

As a beginner, you don’t need a fancy gadget. Try something basic and affordable to learn it to the fullest.


Many users skip this factor until it sores their arms.

Metal detectors made of heavy material with too many bulky details add mass to it won’t make your hunting last due to the fatigued muscles.

Several metal detectors are compact and lightweight like the XP Deus or Garrett AT Pro. These models are qualified with high-performance features in low profile footprints.

The depth it can detect

For deep metal prospecting, people care how far the detectors can penetrate through the earth.

This doesn’t mean you can rely on the specs to expect the machine to reach its depth, but the condition of the soil, the size of the objects and quality of your detector.


This ability to exclude trash is your lodestar. Without good discrimination, you will receive many “spitty” beeps distract you from the real treasure.

In a littered field, chances are you would dig up all the bottle caps and iron with incapable discrimination.


The higher the kHz, the more money you will spend. Having more operating frequencies for more accuracy is good. So, go as high as you can. The more, the better; though, it is not the decisive factor to locate the right digs.

Search Coil

There is physics involved in choosing the search coil, but we want you to the size of the coil.

Different coils work in various fields.

  • Use small coils (6 – 9 inches) for areas with lots of metal litter. This coil size is useful in looking for small targets.
  • Medium coils (10 -11 inches) are the most popular in sites of the low mineralized level.
  • Large coils from above 15 inches look treasures under deep soil but stay away from metal littered sites because the discrimination will react to the ion signal.

Deepest Metal Detectors That Punch To The Greatest Depth

What kind of metal sets off metal detectors?

A: Metal detectors detect non-ferrous metal like bronze, nickel, lead, gold, silver, aluminum, copper, tin, and brass. The discrimination feature will distinguish magnetic elements.

Can metal detectors tell the difference between metals?

A: Typically, a metal detector can detect both non-ferrous and ferrous metals using discrimination because metals respond differently under the AC. That is why we have specific metal detectors for coins, relics, and gold.

How deep will a metal detector detect?

A: It is hard to determine the depth without considering other factors of the detector itself and natural condition in general. But there is a smart way you can measure how deep your coil actually can go on a standard nickel.

The coil will decide how deep you go with the target. Elliptical coils with its fullest circumference can go deeper than the round coils.

The farthest we have experience was up to 15 inches for a quarter with the Garrett AT Pro.

How many types of metal detectors are there?

A: There are 3 main kinds of metal detectors:

  • Beat-Frequency Oscillation: Features one big ring fastened to the base and linked to the oscillator to produce frequency.
  • VLF (Very Low Frequency): Transmitter is responsible for releasing the magnetic field with low frequency into the ground.
  • PI (Pulse Induction): Specifies in deep hunting.

Is metal detecting profitable?

A: If you define profit as money made by selling relics, the answer is yes, metal detecting can be profitable. But only if you find valuable items the world has been losing. Otherwise, what you find may be just rewarding.

Prepare to break a sweat

There you have it, picking the best detector to hit the ground and earn some pennies on the first search.

The deepest metal detector that scored our credits was the Garrett AT Pro with features and price fall all into the basket.
