On the test it has appeared new Fisher 1236-X2 metalldetektor, konstruktiv typical for Fisher, consisting of 3 parts. New 1236-X2 - Fisher's the latest version, its previous model 1235-X. Those who used 1235-X, know that it is simplified enough detector which works adequately, and new 1236-X2 does all the same, but it is more and better.
At first sight, 1236-X2 it is similar on 1235-X, but, has a little unique and valuable enough improvements. From which best it Silencer circuit.
1236-X2 works on low frequency of search 5.7 KGTS. Two modes of search, static (a mode pinpojnt) and dynamic in a discriminator mode.
Four regulators — three of them – multipurpose, switch Silencer, the button pinpojnta, an exit on ear-phones and built in dinamik. Electronics block is put on a bar on runners, as at Fisher's majority, simply and conveniently.
A detector food is carried out from two 9-volt batteries. Has mode VCO.
Управлениe
Sensitivity - a multipurpose regulator. Having turned it counter-clockwise against the stop it is possible to check up a condition of batteries. In this position, 1236-X2 will give out the sound signal specifying force of batteries. Low or not a signal specifies that batteries are time for replacing.
Volume — the loudness regulator as includes/switches off the detector, regulates loudness for built in dynamics or to ear-phones.
Frequency — a useful regulator/switch of frequencies. This regulator establishes working frequency 1236-X2 to eliminate hindrances from detectors working nearby. ‘ 0 ’ it is used for a normal operating mode and establishes frequency 5.7khz. Turn will increase clockwise frequency from 5.5 khz to 5.9 khz.
Disc — Other multipurpose regulator. When the regulator is completely turned counter-clockwise to position Iron, 1236-X2 is adjusted to eliminate ferrous metal and small nails.
Silencer - For us this function was new. Because of high sensitivity, it is a lot of detectors with which I worked in strong mineralizovannoj to soil, generated phantoms and unstable work. Sensitivity reduction to avoid the last, unfortunately, reduces depth of search. 1236-X2 now has 3rd derivative way VLF discrimination “Silencer” which eliminates this problem.
Pinpoint — If to press and keep this button, the detector will pass in a static mode of search that is preferable to definition of the centre of the found object, with function VCO. The located purpose answers with an increasing sound signal.
Field tests:
One of Fisher's better qualities 1236-X2, is simplicity of adjustment, it occupies pair of minutes and you are ready to work. We started to test the detector in a garden, behind the house, the blessing a place was enough, have been established the target test for various depth. So search has begun with installation “on zero” is available in view of the discriminator, installation on 0. As one would expect, we waited signals from all purposes, colour and black, soil normal, any serious mineralization. The coins dug on 35 sm, 5 kop the USSR have not responded, though sensitivity tried on a maximum, in a mode pinpojnta the signal was, but such weak that in a normal state of search it can be caught only in ear-phones. Coins on depth of 25 sm have responded with stable enough signal, in a mode pinpojnta is even more accurate. The helmet has been buried on depth of ~75 sm, and again in a mode of the discriminator the signal was so weak that we simply knew that there a helmet, and so, very difficult. . Though in a mode pinpojnta that that already was more less similar to a signal. On air a helmet saw from distance of 75-80 sm in a mode pinpojnt.
On a beach the detector has proved to be from very good parties, in the first metallomusor in the form of stoppers and uvulas from beer banok has been rejected practically at once with transition in mode Silencer. It has pleased us, completely not badly, coins lifted too adequately, I for myself have noticed that 1236 as that is a bit better myself conducted than its younger colleagues, in the first, at once it was clear that the detector reacts accurately, happens such that feel that the device doubts, one signal another, and here as that is accurate.
Though Silencer works well by search in places of the big congestion metallomusora or it is strong mineralizovannyh soil areas, I do not recommend to use it by search on pure places or by search of the deep or small purposes. It can muffle the weak signal proceeding from the deep purpose or a small product. Use it only if necessary.
The conclusion
With compact, easy on weight and simple on adjustment, 1236-X2 it is possible to make at once the recommendation, as the excellent detector. I do not think that you will make an error if we will get this detector.
As noted above, new mode Silencer works well and the detector confidently behaves there where earlier it was a problem, therefore it is necessary to include in search, zones with a high mineralization or containing a considerable quantity metallomusora. 1236-X2 it is very easy in use and does by its detector for the person with any qualification and experience. Will approach both to the beginner and the searcher with experience.
