Which detector is best for me?
The DD Series is geared towards enabling equipment operators to avoid hitting buried utilities within a defined area. The UI and functions are set up to support a grid search pattern.
The ULTRA series is geared towards tracing a utility from point A to point B. The UI helps the user stay on the path of a buried utility over distance.
The two use cases are not mutually exclusive: You can use a DD locator to trace utilities (the 230 and 130 have tracing modes) or an ULTRA locator to avoid them. It boils down to what you need to do most often.
DD Locators
User-friendly utility avoidance with available onboard video tutorials and optional active signal transmitters.
ULTRA Tracers
The right tool for the job for tracing buried utilities over the long haul.

Passive Modes
Passive mode is the easiest and quickest way to locate energized cables and metallic pipes. You can either select the power or radio modes.
- Power Mode: Locates power signals radiated by energized cables which pose the most significant risk to excavation teams
- Radio Mode : Traces signals originating from distant radio transmitters. These signals penetrate the ground and are reradiated by buried conductive utilities
