On the test model Fisher 1270, this model is partially based on model 1266-X which became the original standard, in the world of searchers which prefer Fisher models 12XX. The first model of this series was 1260-X, in due time the most popular, then Fisher has let out 1266-X which became even better. Model 1270 combines all former functions plus new workings out which we and will try to check up in field conditions, and has been let out 1270 to 70 letiju firms Fisher.
Konstruktiv the detector typical for Fisher, 3 shtangovyj, a handle pistol, an armrest standard with softening small pillows. Ergonomics top-level, weight not big, about 1.7 kg with power supplies. 1266-X had such function Silencer, and here 1270 already has addition to it that does by its more universal and much functional detector. In 1270 began to apply new type of the discriminator separately on ferrous metal as there is also a regulator for standard function of the discriminator, is in the detector and function Treshold though who does not like this buzz, it is possible to work and in silence. The discriminator allows to operate as acceptance of small subjects from ferrous metal, and to full cutting off from search. As in this model there is a trigger, the switch which is on the block of electronics and is switched by means of a forefinger, it is convenient enough to use pinpojntom. You have probably noticed that 1270 works on higher frequency 8.2 KGTS in difference from 1266-X which worked on 4.8 KGTS. It should improve abilities to find out the purpose with low conductivity.
Eats 1270 from two 9 volt batteries, type "Crone", good batteries suffice on 30-40 business hours. The light indicator will warn you a blinking if batteries sit down. In general I recommend to use accumulators of this type, for example 1600 amp/ch, they suffice on 30-35 business hours, then has simply charged them and again it is possible to work.
1270 has three types of the discriminator: Normal Discrimination, Enhanced Iron Discrimination and All-Metal Ground Balanced. The normal type of the discriminator works beginning from nonferrous metals with low conductivity, covers, stoppers etc. and finishing coins. Elimination of ferrous metals mode Iron Discrim manages.
Switch Silencer has the same operating mode as we described in model 1236, but in 1270 has appeared also a range on ferrous metal. Detector operating modes are easy for changing by means of the trigger which is on the block of electronics. For example, to pass in a mode pinpojnta it is possible having pressed and keeping this trigger. Works pinpojnt at 1270 perfectly well. The detector reacts to coins accurately, in the course of testing we had been lifted some coins from depth of 26-27 sm that for such class of detectors very much it is not bad. Certainly there were also phantom signals, but at repeated prohodke on a signal, all rises on the places. Quality Fisher is known by everything, all over the world therefore to concern in details konstruktiva we will not be, all is made soundly, any ljuftov is not present. In general in my opinion 1270 it is possible to carry to detectors of a professional ruler already.
So in field conditions we have carried out the test, soil normal, weather dry. Advantage 3-5 kop the USSR lifts coins confidently about 24-26 sm, it is less than coin on dimensions (2 kop the USSR) see from 17-18 the Buckle from sovdepovskogo a soldier's belt about 45 sm, a bucket of 70-75 sm, 1.3-1.4 metres the car are maximum. All gaugings in a mode all metals, the discriminator on zero, sensitivity almost as much as possible, the coil the standard - 8 inch. Gauging on the car was in a mode pinpojnta. I think that indicators will be better with 10 inch coil Spider. As is and 5 inch coils "Sniper" for these cars.
To describe in detail, as well as that we dug out, I will not be, I think vrjadli to whom interestingly, but the fact that the detector works top-level, it is conclusive. There were we and on a place where the high mineralization of a ground, certainly phantoms were on the maximum capacities, but, having dumped sensitivity, the detector somehow revives. And transition in mode Silencer has an effect, so on this mode at pass over a coin on soil with a high mineralization, the detector works faster, than out of this mode. Mode Silencer Iron very effectively to apply in strongly littered places, the device becomes not so is sensitive to ferrous metal, for the account of it it is possible to avoid all this dust.
The conclusion:
The professional detector, has all functions for the productive search, the improved discriminator with possibility otstrojki both from black and from nonferrous metals independently. High sensitivity. Difficult adjustment is enough not. Function Silencer is improved, now is applied both to colour and to ferrous metal. Will approach both to the professional and the novice user.
