Metal detector minelab iks terra 305. Coils differ in size and operating frequency

The Minelab X-Terra 305 metal detector has a lot of positive reviews from their owners or those who have already used this model. I could not resist and I write my mini review of this device, as well as talk about its pros and cons.

Minelab X-Terra 305 metal detector

The X-Terra 305 is the best in its category. Has a bunch of settings and features. But at the same time, it is easy to operate in which even an inexperienced treasure hunter can handle it.

The 305th model replaced the earlier version of the X-Terra 30 and T34, which are already like history. The new model adds two operating frequencies 7.5 kHz and 18.75 kHz. The 7.5 kHz frequency is intended for large objects, and scans great depth... But the frequency of 18.75 kHz is intended for smaller objects, such as a silver scale, a small pectoral cross and even smaller. But, it does not scan deeply. You need to buy a separate coil for each frequency.

Also in this model, ground tuning and detuning from electromagnetic transmission lines appeared, which allows you to increase the search depth and maximum sensitivity in salty soils and under high-voltage wires.

All ground adjustments are made according to new technology VFLEX. Which greatly improves the microprocessor of the metal detector.

Minelab X-Terra 305 in comparison

It is difficult for me to compare this device with or, or even with. These are completely different devices, and of different weight categories.

ICE 250 is a universal device, suitable not only for coins, it is also perfect for military search. And the X-Terra 305 is more of a coin box.

ICQ 250 does not have settings for mineralized soils, fisher f 2 is also not suitable for this. Only the AT PRO has the ability to tune to the ground, but it does not tune to power lines (electromagnetic transmission lines). The X-terra has it.

Also, X-terra works at two frequencies, the AT pro does not have this feature.

Also, these devices are famous for their high-quality assembly. It is made of very high quality, no armrest will break even under heavy loads. I wrote about this.

Pros and cons of the X-Terra 305 metal detector

I didn't really like his red barbell, it somehow looks glamorous. Although this is a matter of principle, it is not for the shape or color that we buy a metal detector.

Two operating frequencies are very good. But why not make tritium at 3.5 kHz? Then it would definitely be a hit of sales.

I really did not like the fact that some treasure hunters classify it as a "budget metal detector", since not everyone can allocate UAH 4600 or $ 550 for a "budget metal detector".

I really did not like the fact that the metal detector is equipped with a mono coil. Could have delivered DD.

On the plus side, I can say that it has a VDI. Even though it is a device entry level but for, then it already has this feature. By the way, see the VDI responses below.

I will note about new function ground balancing VFLEX, which allows it to work well in clay and salty soils.

VDI digital readout table

This table was made for those who want to learn how to use the VDI function as soon as possible and not dig unnecessary garbage.

Output: in principle, the device is not bad in its class. Ground tuning with the new technology is very pleasing. VDI also did not disregard me. The device is more intended for coins, but with a frequency of 7.5 kHz it is possible to walk around the war. The device is also great for the beach. And you don't need more.

The Minelab X-Terra 305 metal detector is the initial model of the X-Terra series. This device is perfect for finding jewelry in the beach sand, coins and other treasures of metal objects located at a depth of 25 cm for small objects and 60 cm for larger objects.

Equipped with a 9 "Concentric universal search coil and digital microprocessor control unit, which are easily assembled into a single structure on a special rod. Search is carried out at the fundamental frequency of 7.5 kHz with a base coil, as well as at 18.75 kHz when using a coil of a different size and configurations for detecting the smallest objects The digital VFLEX technology used in the Minelab X-Terra 305 has reduced the power consumption and weight of the device, and also reduced the influence of noise inevitable in analog circuits.

Metal detector brains:

The X-Terra 305 metal detector, like the entire X-Terra series of metal detectors, is made according to modern digital technology VFLEX, which eliminates the interference that was inevitable in older analog models. The metal detector is now controlled by a modern microprocessor. This allowed X-Terra to significantly improve the quality of discrimination (recognition of the type of metal), increase depth and sensitivity, and reduce the effect of electrical noise and ground mineralization compared to analog models.

Control keys:



Ground tuning: An important factor affecting the detection depth of a metal detector.
Since we are looking for treasures, coins, etc. not in the air, but in the ground, which inevitably contains various interferences that prevent the electromagnetic signal of the metal detector from penetrating into the soil. These are the remains of various metal waste, minerals with different electrical conductivity, which include clay soils, salty, ordinary red brick, ceramics and various shards and much more. Such interference has a generalized name - soil mineralization. Mineralization is one of the most important factors affecting the detection depth of a metal detector. The better a metal detector can ignore soil noises, the higher its detection depth, sensitivity and ability to distinguish metals.

The X-Terra 305 metal detector model has manual setting on the ground, allowing you to rebuild the metal detector from soil interference and search with a maximum detection depth that is not available to other metal detectors.

More expensive models of metal detectors such as the X-Terra T74 and X-Terra 705 use the automatic tuning on the ground, allowing the detector to always maintain its maximum detection depth regardless of soil composition.


The first figure shows the search without automatic tuning to the ground. Ground noises reduce the detector's effective search depth. The shaded area represents a piece of land that has not been properly surveyed.

The second figure shows how a seasoned professional will avoid missing a target. But this requires frequent manual balancing of the detector, which is time-consuming.

The third picture shows the automatic soil tuning system. The metal detector maintains sensitivity and depth throughout the entire search area without missing targets. The metal detector adjusts itself to the amount of soil clutter, always maintaining the maximum detection depth.

Electrical interference cancellation: Another important factor affecting the detection depth is electrical noise. The X-Terra 305 metal detector model has the ability to tune out such interference. There are a lot of examples when tuning from electrical interference is simply necessary, for example, when you have to work closely with other metal detectors, for example, in the attic, in the basement, at a gathering of treasure hunters or near a power line.

“My friend and I were searching in a very promising field, next to the power line. The site was rich, coins went one after another, stretching in bulk under the power line. Working nearby, I noticed that my friend with a cheaper model of a metal detector, approaching the power line, turned around and went back to the place seemingly long ago knocked out by us, glumly watching me, but not daring to cross some invisible line. The reason was the same power line that interfered with his metal detector, preventing him from working in its vicinity. The metal detector stopped obeying, phonil, showed what was horrible and did not succumb to any settings and persuasions. My anti-jamming metal detector worked stably even when I was standing directly under the high voltage line. The ability to detune from eclectic interference allowed me to calmly continue the search under power lines and make many interesting finds. Rudolf Kavchik ".

Search coils: The X-Terra 305 metal detector model is equipped with a 9 "Concentric 7.5 kHz universal coil, suitable for most search conditions. coils of other sizes and configurations are used.
