VLF METAL DETECTOR TESTS - WHAT IS THE BEST ?
METAL DETECTOR TESTS FOR DEPTH RESEARCH (second page)
By Alain Châtillon, Président Latincom-Mex SA & Deepers Detector Co Email : [email protected]
IMPORTANT OBSERVATIONS :
Air testing test all metals normally gives much greater distances than those obtained in the ground test. Certain apparatus lose up to 13 cm between both, but when the detector gives a very good result in the air, it is generally - to a lesser extent - is powerful in the ground test, too.
The Ground Test for all metals is performed in a mixture of 50% bio-soil and 50% mineralized river sand, each moistened and measured before each test. Adjusted at maximum capacity many apparatus become unsteady (above all the ones with metal casings which tend to self-detect from a certain range on).
Excellent notation for the Garrett GTI 2000, easy usage, stable electronics, clear responses, good ergonomics, casing ABS, battery compartment as far from searchcoil as possible. Very good results with Fisher CZ20 (though a bit heavy). The Discovery Baron base module also gives reliable results. With its finest adjustment, the White’s 6000 Di Pro offers good detection depth but becomes rapidly unsteady. The Minelab Sovereign XS-2 works very correctly but uses up battery power in no time. Special mention for the Tesoro Lobo Super Traq, a very steady apparatus and which should give the best performances with a round searchcoil 10 1/2" (which we haven’t been able to test).
