Comparison Minelab X-Terra Pro vs Minelab Equinox 600

The size of the standard coil (frame) of the metal detector. Theoretically, the larger it is, the deeper the device is able to “see” and the more space it captures in one pass, but the worse it is suitable for searching for small objects and the lower the accuracy with which it localizes them. At the same time, these characteristics depend on so many other factors that in fact, the size of the coil itself affects them very little.

Note that for coils (frames) of an elliptical shape, only one size can be indicated — along the length.

The number of individual operating frequencies at which the metal detector can operate. For more on the frequencies themselves, see "Detection Frequency" below; here we note that the more options ( 3 frequencies and more) are provided in the design, the wider the capabilities of the metal detector, the easier it is to adjust it to the specifics of the objects being searched and the environment. However, most models have one frequency.

The operating frequency (or frequency range) of the metal detector. This is one of the most important parameters when choosing a device, because the optimal frequency for different cases will be different — depending on the size and material of the items being searched, the characteristics of the soil and other factors. Detailed recommendations on the choice of frequency for each specific situation can be found in special sources; And already on the basis of this information, it is worth choosing a specific model.

Note that the actual frequency at which the metal detector will operate also depends on the installed coil — they are usually made for a specific frequency. Therefore, to use the full capabilities of the device with the ability to adjust this parameter, you may need replaceable coils.

The number of pre-installed programs for searching for various materials. Their number reflects the capabilities of a particular model, allowing you to start working right off the bat.

Regular metal detector search programs include detection of coins, all metals, jewelry and relics. In some models, this list can be expanded with "Beach" programs, custom (user) detection mode, etc.

— LCD display. The presence of its own display in the design of metal detectors. This feature makes working with the device more convenient and visual: through the display, you can display more different information than with the help of an audible alarm or indicator lights, and it is easier to perceive. On the other hand, such devices are more expensive than similar models without a screen.

— Arrow indicator. The presence in the design of the metal detector of an analogue dial indicator to display data on the search process. Such an implementation is much more modest and cheaper than the same LCD display, but an order of magnitude more convenient than without visual notification at all.

— Display backlight. The presence of a backlight allows you to use the display of the metal detector in low light conditions — up to complete darkness. Note that this function can be useful not only at dusk, but also in the daytime — for example, when searching in a dense forest in cloudy weather. See above for details on the display.

— Built-in speaker. The presence in the design of the metal detector of its own speaker. Such a speaker allows you to use the device without headphones, which are not always convenient, and sometimes unsafe (for example, when working in places where traffic can move).

— GPS module. The presence of a GPS satellite navigation module in the design of the metal detector. This module allows you to determine the current geographic coordinates of the device, and the options for using this data can be different: recording search routes, fixing the places of individual finds, and even full-fledged navigation with laying routes from point to point.

— Armrest.... The presence in the design of the metal detector of an additional support in the area of the operator's elbow. This support reduces the load on the hand, and also makes the hold more stable and at the same time controllable, allowing you to comfortably hold the device in one hand.

— Headphone output. The presence of a headphone output in the design of the metal detector. This can be either a standard connector that allows you to connect any compatible "ears" (for example, a 3.5 mm mini-jack output, popular in portable audio equipment), or an original proprietary interface that allows you to use only specialized "native" accessories. Anyway, headphones are often more convenient than a speaker, as they allow you to hear the signals from the device well even in a rather noisy environment.

— Headphones. The presence of headphones in the scope of delivery of the metal detector. Usually, such headphones have high quality and accuracy of sound transmission, so that the user can be guaranteed to hear all the signals and tone shades of the signals. "Ears" can be wired and wireless, and in underwater models (see "Type"), they are, respectively, made waterproof. This function is convenient because you do not have to search and purchase the best headphones for the metal detector on your own.

The longest possible time of continuous operation of the metal detector without changing or recharging the batteries. Usually, some “perfect” time is indicated for the most optimal mode: constant stable operation of the coil without unnecessary energy consumption for sound signals, display indications and other additional functions, fully charged batteries or high-quality replaceable batteries, etc. Therefore, the actual time of continuous operation is likely to be somewhat less (how much depends on the features of the work). Nevertheless, this parameter describes well the battery life of the metal detector and allows you to evaluate its suitability for work "in isolation from civilization" (as well as the estimated number of spare batteries that may be needed for a complete survey of the desired territory).

Additional accessories and parts included with the metal detector. These can be devices for protection and ease of carrying in the working position or during transportation — belts, bags, cases, rain covers for the control unit; special equipment required for work — for example, a grounding rod for models with the RF operating principle; and other additional equipment. The presence of batteries and a charger for them in this paragraph is indicated only if the device uses replaceable elements (see "Power"), because cordless metal detectors are by default equipped with a battery and “charging”, and there is no need to specify this. Also, this paragraph does not cover spare replacement coils — their presence or absence characterizes the “Number of coils” paragraph.

The total weight of the metal detector in the working position is with the installed coil and batteries (if both are removable, see above). This parameter is quite important, taking into account the fact that during operation the device has to be kept on the weight: long-term use can be very tiring even with a relatively small weight and the presence of an armrest (see above). Therefore, light weight is a noticeable advantage for any metal detector. At the same time, other things being equal, lighter models tend to cost more, so you can use another option — a shoulder strap that reduces the load on the hand. And for underwater metal detectors (see "Type"), this parameter is not particularly relevant, because. objects underwater lose a significant amount of weight.
