Sea Hunter Mark 2 works under scheme PI which does not react to salty water or black sand. This technology PI, is specially calculated on search in salty water, on a beach, and allows to conduct search in crude soil. A unique minus, absence of the discriminator. Though some PI detectors have discrimination of metals. Though it is possible and to tell that at Mark 2 there is a similarity of the discriminator which is at VLF detectors, it is named, discrete elimination threw - dust, supposes elimination of the certain undesirable purposes.
The metal detector has two modes of the discriminator, standard and discrete. The standard mode works, as well as all PI detectors and deduces a constant sound signal which is called Treshlod and which changes when the coil is over the purpose. Discrimination in this mode is possible, but at increase in the discriminator depth of search will be reduced, in the most extreme position of the discriminator it can decrease to 50 %. The discrete way of the discriminator works as usual VLF the detector. The coil is required to be spent over the purpose for reaction to metal, it is a dynamic mode. Discriminator use supposes, that you have precisely chosen a certain range of the purposes to reject them without loss of depth of detection. The search coil 8 inch, quality good, a capture zone as.
The metal detector is completely water-proof, search can be conducted on depth to 200 foots, the detector from 8 batteries or accumulators of type AA eats, there are power supplies separately from the electronic block and possibility of course of water is excluded. With itself there is a cartridge training to video having looked which, you receive the full instruction on use, the truth in English.
Field tests:
This season simply does not carry, have received Hunter Mark 2 already in the end of a season. But as at us strong the spirit submariners possible taki will agree with one, on check, preliminary having supplied it (only after the test) with a vodka bottle. Detector options before immersing: Standard Trash Elim, Elimination on “0”. 2 coins for 20-25 minutes, anything valuable have to begin with walked on the edge of coast, it would be desirable to check up simply how there is a response to damp soil. Naturally diskrim on zero, caught all purposes. Threshold have switched off, buzz on the earth of special effect by search has not given it. Further, the colleague began to come into water in regular intervals, thus the detector was in working order, has reached approximately on a breast, at change of air with water Mark has not submitted special glitches or what problems.
It was possible to plunge to our tester on 3 metres as much as possible, it under water has found some fragments from metal, well and it it would appear enough that more less will be defined with this detector though, certainly it was necessary potestit it still few times under water but unfortunately weather at all did not allow. The situation has appeared basically similar to all detectors which work under water. At immersing adjustment of a threshold sound on 3 was used, elim on 0 and the discriminator type varied in the standard at a find of the purpose and in a discrete mode. What conclusion can be made on these two positions, in the first in a standard mode it is worked more more habitually, we add a little a threshold sound and all purposes are more less clear at detection, the sound increases at purpose approach to the coil accordingly, elim not so strongly influences depth of search, but it is necessary to remember that if zagrubit discrimination more strongly that and depth of search will decrease. In a discrete mode we receive at once our old, kind VLF the detector, all same options, elim discriminates metal, the above its installation, the bolshee a ferrous metal exception. In general itself Mark 2 has been developed as PI the car but. There is also an alternative in a mode of the discrete discriminator. Depth of search with the standard coil on a coin in size with 15 kop the USSR – 20-23 sm, size with 2 kop the USSR – see till 18-19 larger purposes, probably to find out on distance to 40-45 sm, it is bank from koly, a mobile phone. The maximum depth of search for this purpose impulsnika to 1.2 metres.
The resume
Mark 2 good not expensive PI the metal detector, is intended for search under water. Especially does not differ from the predecessor, the discriminator is executed typically for PI cars, reactions to salty soils are almost brought to naught. Very conveniently gathers in the compact tool for search under water, will approach a wide range of divers in particular to beginners who wish to try ponyrjat with the metal detector.
