5 best deep metal detectors

To search in the land of large objects are used depth metal detectors. They have certain parameters that distinguish devices from standard metal detectors. These features are important to consider when choosing a suitable machine.

• First of all, most of the deep metal detectors do not have discrimination. And to many users, it does not matter from what metal the artifact of the Great Patriotic War, located at a depth of 2-3 m, is made.
• Depths can be equipped with a familiar coil or a large frame. For confined spaces, it is more convenient to use the familiar coil, it allows the device to be used by one operator. But in the case of a framework, an assistant will be needed, but the coverage of the study area will be more.
• Many manufacturers indicate an increased detection depth. Of course, if military equipment (tank) is hidden under a 6m thick layer of soil, then many depths will fix the target. But machine guns or helmets can be detected to a depth of 2 m. In other words, the larger the object, the deeper it is the device.
• Experienced search engines most of all appreciate in the metal detector not the depth of detection, but the stability of working with different soils. First of all it concerns the mineralized soil. Also, the device should ignore the small debris, which is abundant in the upper layers of the soil.

Our review includes the best deep-seated metal detectors. The rankings took into account the opinion of professional search engines and user reviews.

TOP 5 best deep metal detectors

5 Treasure Hound depth nozzle to metal detector Garrett GTI 2500

A simple and affordable way to retrofit a conventional Garrett GTI 2500 metal detector is to install the Treasure Hound depth nozzle. The two-frame design turns an ordinary device into the depths. At the same time, the ability to determine the type of metal is lost, but the search depth reaches 3 m. With regard to real research, the device sees a soldier’s helmet at a depth of 1.3 m, and artillery weapons can be found at around 1.7 m. It should be noted that the nozzle is produced for a long time, so it does not make the best metal detector today. But an unusual device adds to the practicality of the search device.

Users in the reviews indicate all the pros and cons of the depth of the nozzle. The main advantages are the availability and ease of modernization. But it cannot be used with other metal detectors, which significantly limits the scope of application.

4 Fisher gemini-3

In developing the Fisher Gemini-3 depth metal detector, American designers focused on mobility and versatility. The device is lightweight (2.8 kg) and compact. For transportation, it can be folded into two briefcases, and it can be brought to full combat readiness in 2-3 minutes. The device is equipped with a shoulder strap, the length of which can be adjusted to any height. One button turns on the transmitter and receiver, you can adjust the operation of the metal detector for different types of soil. The depth of detection of large objects reaches 6 m, but the model will find a small container with coins at a depth of up to 1 m.

Users in the reviews note not only affordable price, mobility and versatility, but also the reliability of the coil, protected by a casing.The disadvantages of the device owners include the instability of the settings, because of what often occurs false positives.

3 Detech SSP-5100

Detech SSP-5100 depth metal detector is based on PI induction technology. Thanks to this scheme, the depth of detection of large objects can reach 9 m. Experts note the high sensitivity of the device to objects of various sizes (up to 6 m). For example, the depths' soldier's helmet finds at 1.6 m, and the machine gun - up to 2.0 m. The transmitter emits waves at a frequency of 100 hertz, the model quickly adjusts to the ground. The manufacturer has thoroughly worked on the display and intuitive menu. The device is suitable not only experienced search engines, but also for beginners. Thanks to the automatic mode, the device independently amends the ground and the magnetic field. The connected frame has dimensions of 1x1 m, so you will need an assistant for the search.

Users consider depth to be the best device for serious exploration. He is easy to work and unpretentious. Only the price, according to experts, is somewhat overpriced.

2 White's TM-808

Among the deep metal detectors, the most popular in Russia is the American development White's TM-808. Users of the search engine "Yandex" show increased interest in the device for a number of reasons. First of all, in practice, the motto of the company "To Customers - Quality and Affordable Prices" works. The device is easy to use, it is equipped with only coils. Therefore, a single person can use a metal detector. The manufacturer claims a detection depth of up to 4 m, although in practice this figure looks more modest. The model demonstrates the best performance in a limited space. TM-808 cannot determine the type of metal, which is not always necessary.

Although the device is already outdated technically, but the feedback continues to come mostly positive. There are several drawbacks to the American depths. This is the deformation of the coils and the fear of moisture.

1 Nokta Invenio Smart

The Turkish depth metal detector with the Nokta Invenio Smart georadar made a real sensation in Germany at the IWA OutdoorClassics exhibition, which was held in 2018. The novelty is a unique intelligent system that not only signals the presence of metal in the ground, but also analyzes the data and shows the object in a three-dimensional image . In addition, the device accurately indicates the depth, as well as the overall dimensions of the find. With the help of the depths can find a variety of objects and anomalies in the ground. It can be small coins and weapons, tunnels and caves. You must first select the appropriate program. Experts point out excellent discrimination, so the search engine will not be distracted by digging out unwanted metals.

The high price does not yet allow a wide range of search engines to acquire such a device. Professionals in the reviews admire the novelty, predicting a great future.
