Key Features & Benefits
1. Powerful & Versatile 2273M Locator:
-
Multi-Function Operation:Â Functions as a high-performance inductive locator, a sensitive inductive probe (for close-proximity tracing), and a precise fault-finding tool.
-
Active & Passive Modes:Â Actively trace a specific line with a signal from the transmitter, or use passive modes to detect power (50/60 Hz) and radio (RF) signals on unknown utilities.
-
Dynamic Depth & Current Display:Â Provides real-time, on-screen depth estimates and current measurement (mA). This allows you to not only find the line but also identify it by signal strength and trace its path with confidence.
-
Peak/Null Modes:Â Switch between peak (arrow) and null (dip) response modes to suit different locating conditions and user preference for the highest accuracy.
-
Rugged, Ergonomic Design:Â Built to withstand harsh job sites with a weather-resistant, drop-tolerant housing. The intuitive interface and comfortable grip reduce user fatigue.
2. High-Output 5250 Transmitter:
-
Multiple Coupling Methods:
-
Direct Connection:Â Connect directly to a known pipe or cable for the strongest, most precise signal.
-
Inductive Clamp: Couple a signal onto a specific line without a direct electrical connection—ideal for live power or communications cables.
-
Inductive Mode:Â Broadcast a signal from the transmitter placed over the ground to induce a signal onto buried utilities without any contact.
-
-
High Power Output:Â Provides multiple power settings to push a clear signal through long distances, difficult soil conditions, or congested areas.
-
Advanced Signal Patterns:Â Offers multiple frequencies (e.g., 512 Hz, 8 kHz, 33 kHz) to optimize the signal for different types of utilities and ground conditions.
3. Superior Fault-Finding Capability:
-
The system excels at pinpointing faults in buried cables, such as sheath faults in jacketed power cables or shorts in direct-buried telephone lines.
-
The A-Frame accessory (often included or available) works with the locator to provide a precise distance-to-fault reading, speeding up repairs and minimizing excavation.
