The highlighter tool lets you filter finds by material without searching for them. The discrimination function is introduced into metal detectors for targeted searches – so that the devices do not react to useless garbage such as bottle caps, pieces of fittings, chips from cigarette packs, etc. This simplifies the search process and saves the excavator from unnecessary work of extracting uninteresting objects from the ground.
In advanced detector models, information about objects in the soil can be obtained from the numerical values of the metals that are displayed on the screen. Entry-level metal detectors do not have such options, but getting a detection using discrimination is not difficult.
With no discrimination, the detector sees all metals within the detectable range. By increasing the discrimination value, the filtering of metal debris begins. The best way to practice is to scatter some sample targets over a short distance. Starting at the lowest highlight point, scan these objects and gradually increase the highlight threshold until the object is discarded.
Store the results in your memory or write them down – this way you can learn to distinguish literally “by eye.” The function saves effort and time, helping you decide whether to drill or not.
Metal Detecting Tests Discrimination Vs Performance
what is a distinctive metal detector
The second oldest model “Asqui” in the line of metal detectors Garrett wears the article Ace 250. Is this device worth its money and what is its advantage over the “junior” fellow? You can find the answers to these questions in this review.
Garrett Ace 250 features
As for the distinctive features of the 250th model from its predecessor, here are the following points:
Fully revamped control unit
More search modes
Advanced Discrimination Settings.
Unlike the 150th Aska, the Garrett Ace 250 has more controls. The number of sectors on the sensitivity scale has increased from 4 to 8, and the identification scale has 12 divisions, which is 7 more than ace 150.
However, the main distinguishing feature of this model is the presence of a discrimization function, which allows you to exclude certain parts of the scale from the search. It should be noted that memorizing the settings of discrimination and sensitivity is possible only in the user mode. When using other modes, the settings are automatically reset to the factory after the metal detector is turned off.
In other words, the Garrett Ace 250 is an upgrade of the previous modification and, it is worth noting, very successful.
Garrett Ace 250 Features
The metal detector of this model is designed according to the VLF scheme and has the following technical and operational characteristics:
Frequency – 6.5 kHz;
adjustable barbell (101-129 cm);
Power – 4 AA batteries
6.5 x 9 inches concentric immersive coil;
Work time (maximum sensitivity) – 15 hours;
5 search modes – “all metals,” “coins,” “relics,” “jewelry,” “user mode.”
If we compare the characteristics of the Ace 250 with the technical performance of the same 150th “Asaki”, the new model added 2 new search modes. Otherwise, both metal detectors are identical.
Depth of detection
According to the manufacturer’s official website, this model of metal detector is able to detect a coin (15 kopecks 1924), lying flat, at a depth of up to 17 cm. As for large objects, Garrett Ace 250 is able to detect them at a depth of up to 1 meter.
Garrett Ace 250
In Ukraine, the metal detector of this model is presented only in the modification of the standard, which includes:
6.5 x 9 inches coil;
As you can see, the metal detector is equipped with everything you need to search for “treasures,” and the presence of training videos will allow you to quickly learn all the nuances of working with this device.
