The Vivax D18 Sonde with Eyelet End Cap is a specialized and efficient locator accessory engineered for high-precision underground tracing. Measuring just 18.5mm in diameter and 80mm in length, this compact sonde is optimized for navigating tight spaces and narrow conduits where larger transmitters cannot pass. It operates on a standard 33kHz frequency, delivering consistent signal strength for utility maintenance and construction professionals.

How deep can the Vivax D18 Sonde track?

This sonde provides dependable detection capabilities for underground utilities at depths of up to 4.5 meters (15 feet). The 33kHz signal is optimized for penetrating various soil types to ensure accurate pinpointing from the surface.

What materials is the D18 Sonde compatible with?

The D18 Sonde is specifically designed for use within non-metallic pipe materials to avoid signal disruption or shielding. It can be integrated into PVC, clay, or concrete piping systems without interference.

What is the purpose of the eyelet end cap?

The integrated eyelet end cap provides a robust attachment point for securing the device to a pulling cable or flex rod. This functional design feature facilitates the easy deployment and retrieval of the sonde through complex ducting systems.
