Profile: Kolectric Research Ltd. provides rebar detection services. Our MC8020 model uses a newly designed probe believed to incorporate the most accurate depth and bar size determination routines available. This, combined with extremely good resolution of multiple bars, sets the unit apart from others, and sets the benchmark for cover meter surveying. The new K9 probe searches using a version of "pulse induction" techniques proved to give more accurate results in areas of bar congestion. When the instrument selects the bar size accurately, then precise depths can be displayed. 8020 uses high-powered processors in conjunction with pulse induction search technology. The automatic bar diameter determination within the parameters defined, enables very precise depth readings and bar orientation to be obtained even where there is the need to discriminate between bars on close centers.
