My Top Pick: Garrett ACE 400
- Extremely accurate for its price
- Easy to use
- DD coil for better performance
- Large digital screen
- Significant deep search
- No ground balance adjustment
After considering tons of metal detectors, we finally decided the Garret ACE 400 to be our top pick. This is the newest model in the ACE product line of Garrett, so its feature has been developed and upgraded a lot compared with the old ones such as Garrett ACE 250, ACE 300 and even the 350.
One of the most distinctive features that has been enhanced is the Iron audio. This combining with the pulse-width modulation will bring the detector’s discrimination into the whole new level! Sometimes, when you search for gold, you will choose the All-metal mode as you don’t want to miss out on even the smallest gold nugget.
The problem of this mode is your machine cannot differentiate gold from trash, particularly when you’re hunting in mineralization, so there is a high likelihood that you will fall into the trap of fake signals from metal litter.
And, the Iron audio is born to help you get away from such time-wasting issue by letting you hear the different sounds between trash and treasure. The pulse-width modulation is an extra feature that makes those sounds clearer and more accurate.
This machine is also straightforward to use, so beginners will love it. Only one small hindrance here is that the ground balance is fixed, so you cannot adjust it based on the ground condition.

Best For Gold & Silver: RM RICOMAX GC-1037
- Lightweight
- Easy to assemble
- Various target categories
- Large LCD screen
- No ground balance adjustment
In our opinion, RM RicoMax GC-1037 is an optimal option for amateur gold diggers. The target category menu is so diverse with up to six clearly defined segments, and there is one that is solely for gold.
By dividing the target scale into different groups like this, it makes it easier for you to determine what type of detected metals.

We do not promise that you will become rich or get tons of gold nuggets, but definitely that RM RicoMax GC-1037 will live up to your expectations and help you get some hidden treasure underground.
Best For Beginner: Fisher F22
- Affordable
- Lightweight
- For beginners
- Great discrimination
- Weatherproof
- No ground balance adjustment
- Pretty basic for intermediate to advanced hunter
Fisher F22 is packed with the most necessary basic features to promise helping you learn to the fullest from the beginning.
It comes with a 9” waterproof concentric coil. The concentric coil is the coil type dominating entry-level detectors because of its reasonable price. That’s also the reason why it’s not as accurate as the DD coil.
Still, luckily, the developed coil design in this model has made up that traditional weakness. It’s triangulated elliptical shape, meaning that it’s smaller and narrower, which will better the product’s targeting good item ability.
Lightweight is a plus point as well because it allows you to keep hunting for a long time without uncomfort, especially when you’ve just started to take up this hobby and lack a lot of experience.
Weatherproof is a pretty new feature that not many detectors have. Frankly to say, we don’t find it really helpful or have any outstanding support, but perhaps it could help improve the machine’s durability.
Although this product has some additional features that do not show up in some entry-level detectors such as iron audio and 2-digit numeric target identification, it’s still just a more ideal choice for an amateur than a mid-level or more.
| Fisher F22 Specifications | |
|---|---|
Operating Frequency | 7.69 kHz |
Search Coil | 9” triangulated elliptical concentric waterproof search coil |
Audio Tone ID | 4 |
Maximum Search Depth | 9 inches |
Highlight Features | 10 adjustable sensitivity levels; numeric target identification; iron audio |
Fisher F22 can be considered as a blast in the niche of metal detectors for beginners.
Best For Coin: Bounty Hunter Land Ranger Pro
- Has auto and manual ground balance
- Lightweight
- Able to be used in very shallow water
- Can cover a lot of ground quickly
- Pinpoint button
This Bounty Hunter Land Ranger Pro feels good in hand with lots of amazing features of a mid-range metal detector.
One of the most delightful features of this machine is its ground balance adjustment, which really comes in handy when you have to move and change hunting location consistently. It’s quite impressive and rare for a detector that is more than $200 to own a manual/ auto ground balance. And, the great thing here is it works like a charm and not less than a high-end product!
The 7.69 kHz frequency is not perfect for gold prospecting, though it’s ideal for bigger items or coins. Moreover, while the search coil is waterproof, the whole unit is not, so you cannot use it for beach or freshwater hunting. However, if you just intend to apply it for very shallow water, it’s acceptable.
We appreciate the pinpoint mode, but to be honest, Bounty Hunter really needs to improve its pinpointer button on this model as it’s totally not reliable. It’s flaw, hard to use and its durability is inferior, which is completely different from other features.
| Bounty Hunter Land Ranger Pro Specifications | |
|---|---|
Operating Frequency | 7.69 kHz |
Search Coil | 11” DD elliptical waterproof search coil |
Audio Tone ID | 4 |
Maximum Search Depth | 10 - 12 inches |
Highlight Features | 7 detection modes; 2-digit numerical system; enhanced V-break; iron audio |
Bounty Hunter Land Ranger Pro has all the top-ranked needed factors to be the best metal detector for coins, but its pinpoint button quality should be taken into consideration if it’s an essential feature for you.
Best For Brass Relic Hunting: Garrett AT MAX
- Versatile
- Waterproof to 10 feets (3m)
- Both manual and automatic ground balance adjustment
- Fast response speed
- Pinpointer is accurate
- Pricey
Once you choose to invest in the Garret AT MAX, it means that metal detecting is no longer a fun hobby but a serious passion for you to follow. This product stands on the boundary between a mid-range and an advanced metal detector.
This All-terrain machine can tackle a wide range of extreme ground conditions for different hunting purposes, from coins, jewelries to brass relics. And, besides having some available great features that have made the name for Garret’s products, there is something new at this.
The most bang-for-the-buck feature that we’re into in this model is its built-in pinpointer as it can target the location of the object with ridiculous precision.
Now, instead of being equipped with Bluetooth-technology headset as Garrett’s old models, this guy comes with the Z-lynk wireless technology, which has greatly fixed the slow data transferring or the signal delay that often appears with the Bluetooth.
Everything is perfect except its price. At this price range, you might confuse whether you should invest more to upgrade to a truly advanced detector or not, or if you have a tight budget, maybe you should stay with the Garret ACE 400 or the Bounty Hunter Land Ranger Pro.
| Garrett AT MAX Specifications | |
|---|---|
Operating Frequency | 13.6 kHz |
Search Coil | 8.5 x 11” waterproof DD search coil |
Audio Tone ID | 3 |
Maximum Search Depth | 12 inches |
Highlight Features | 44 iron discrimination segments; Z-lynk wireless technology; iron audio; pulse width modulation; 4 search modes |
If you finally want to get serious in metal searching or some basic detectors do not fit the bill anymore, Garret AT MAX is a pro-grade choice that is worth every penny.
Best For Beach: Teknetics Delta 4000
- Waterproof coil and control box
- Lightweight
- Easy to use
- Good discrimination
- No ground balance adjustment
- Not reliable pinpoint button
Teknetics Delta 4000 is a great little metal detector. To say the least, it can outperform a lot of products with the same abilities but cost more than twice the price.
This, of course, is not a model that you can dig into right away at ease, but overall, it just takes a little to get used to and totally take control over it, even if the user is a kid.
So, what are other factors that make this so good? The first one that must be mentioned here are its notching and discrimination, which really aid in getting rid off the junk. It also provides you with a 0-99 number scale, which is often found on some much more expensive units.
The tip that we found to make this machine 100% perform its ability in beach hunting is you should adjust the sensitivity to fit with the fixed ground balance. Furthermore, most metal detectors are set for US coins but actually there are also a massive number of UK coins on the beach, so if you know how US coins are read on the display, it will be a huge advantage.
This guy does not show any weakness in the wet sand condition as well when it can find coins at the depth more than 6 inches.
In general, Teknetics Delta 4000 does not possess any special features, but it gets most of the detector’s salt-water jobs done as expected.
| Teknetics Delta 4000 Specifications | |
|---|---|
Operating Frequency | 7.8 kHz |
Search Coil | 8'' waterproof concentric coil |
Audio Tone ID | 3 |
Maximum Search Depth | 8 inches |
Highlight Features | Adjustable sensitivity; 2-digit numerical target ID system; adjustable discrimination |
Teknetics Delta 4000 is not the cheapest by any stretch but an affordable and worth-trying unit to break you into the hobby.
How To Choose The Deepest Metal Detector?
Although you have already been provided with some of the best detectors above, it’s still highly recommended that you should have in hand some essential buying criterias to make the most appropriate decision. Let’s make a brief walk-through of them!
Search Coil
There is a collection of considered factors about the search coil, but today, as our title is choosing the deepest metal detector, we will just dig into the aspect that affects the searching depth most, which is size. When you read detectors’ specifications, you must see a variety of coil’s sizes, right? So, the question popping up here is, is there any difference among them?
Many people just simply think that the larger, longer the coil is, the deeper it can search. Well, that conception is true, to some extent, but not enough! To make it clear, we divide all coil sizes into three main groups:
- The first one is small coils, which lengthen from 6 to 9 inches. Normally, these coil xlengths will bring you the shallowest searching depth, but in the areas with lots of metal litters, they can be compared with the larger sizes or even work better because of their great discrimination.
- Next, there are medium coils, which range between 10 and 14 inches. Besides, the most common length range that you often come across in a mid-end metal detector for deep hunting are 10 and 11 inches. And these lengths are most suitable for low-mineralized level sites.
- And, when the coil is over 15 inches, it’s a large one. This can hunt deep down the soil to find treasure, but will be annoying for littered metal areas.
Searching Depth
How deep that one metal detector can reach is not only depending on the coil, but also many other external factors such as ground conditions and the object sizes. And, different models of detectors have been specifically designed for a wide range of purposes.
For example, some are waterproof for sea hunting, while some with high frequency can handle mineralized grounds. So, identifying your purposes and locations is also a necessary step contributing to maximize the searching depth.
Frequency
The more frequencies that a detector features, the more expensive it is. Still, that also comes at its quality and accuracy. For those who don’t know, each type of metal has its own detecting frequency.
Therefore, of course, a multi-frequency detector will outweigh the single-frequency one when it comes to versatility. However, after all, although frequency is important, it’s not the sole decisive feature.
Discriminication
Discrimination is the ability to skip trash and focus on your wanted searching items. Without a good level of discrimination, you will receive a lot of beeping during your searching process as your detector cannot clearly distiguish between trash and valuable objects.
Weight
Weight is not the factor that will affect the searching depth, but it decides your comfort when using. Many detectors tend to ignore this until the problem comes that their arms get hurt after a long period holding a heavy detector.
So, please always keep this feature into consideration before buying your detector. Some lightweight and compact machines will enable you to enjoy this special hobby during the whole process instead of putting up with a pain in the neck.
Price
The most expensive sometimes might not be the best. So don’t push your budget too hard to run after a fancy model. Especially if you have just started out taking up this field, perhaps some advanced features from that machine are unnecessary for you.
A basic, affordable detector but still can meet your needs is all that you need to learn about metal searching from scratch!

FAQs
How deep can metal detectors detect coins?
This is a tough question to give an accurate answer. When mentioning depth, each metal detector will have its own maximum depth for different metal objects’ sizes (in this case is coin size) in different ground conditions.
Can metal detectors find coins?
Yes, of course. There are even some models designed with specific features just for finding coins.
Where is the best place to find old coins?
To be honest, oil coins can be found anywhere, but we suggest that you should find them around your house and neighborhoods first. After that, you can prioritize going searching around churches, old parks or old battle grounds.
What's the best frequency for metal detecting?
It’s the fact that no frequency is ideal for all kinds of metal detecting. Each metal category, and even each size of one metal will have different conductive responses. That’s why a single-frequency, no matter how the manufacturers have advertised that they have found the best frequency for metal detecting, it’s just a compromise. So, more is better, get a detector with as many frequencies as you can!
Can you detect metal in a cemetery?
Yes, you can, but please make sure that you will never do anything disrespectful, illegal things!
Conclusion
The metal detector that has taken the first place in our heart is the Garrett ACE 400 but maybe, after reading our review, you will realize and choose your own best deal.
