Scope & limitations
Manufacturers publish center frequencies; real performance still depends on site conditions. We pick hardware to match the stated purchase order—not to win a theoretical depth contest.
Outdoor utility locating
Lower-frequency antennas often help when cover is deeper and targets are larger conductors or pipes—but you sacrifice horizontal resolution. In congested corridors we may use multiple passes or correlate multiple lines of evidence. Moisture still dominates; see soil moisture and depth.
Concrete and slab scanning
Higher-frequency antennas typically resolve closely spaced features near the surface—rebar mesh, conduit bundles, radiant tubing risk zones—when the slab section cooperates. That maps to our concrete scanning offering, distinct from turf or asphalt utility routing under GPR & locating.
Decision support
If your team is torn between slab work and exterior trenching, start with concrete scanning vs utility locating before booking.
