Our Goal at Xenogenesis RADAR is to help you hit nothing but concrete. We try to help our customers avoid all Rebar, Conduits, PT, Beams, and Anchors. Some times there just is no clear location and moving the hole over a foot in another direction is not an option. In these cases, we try to help you pick the safest option available. In the picture above there was not a good option to avoid all contents of the concrete slab, so the technician would choose the clearest example of rebar and make a recommendation of where to core.
