A new addition to the 3M™ Dynatel™ locators 2200M series, the 2220M locator is designed to provide a simple and accurate solution to locate buried pipes, cables and sondes in even the most challenging field conditions. The rugged, highly sensitive receiver uses two active trace frequencies and provides a bar graph, signal strength and direction indication to the pipe/cable. In addition, the receiver is designed to detect passive power and auxiliary frequencies that do not require the use of a transmitter.

3M™, 7000133066, Locator, Series: 2220M, 0 to 30 ft Measuring, +/-2 to 10 % Accuracy, (8) AA Alkaline Receiver, (6) C Alkaline Transmitter Batteries Power Source, Backlit LCD Display, 0.1 dB Resolution, IP54 Enclosure

• Four active trace frequencies which can be used individually or simultaneously to compensate for varying field conditions
• The receiver incorporates passive power and auxiliary frequencies that do not require the use of the transmitter
• Graphic display to distinguish between targeted cable and other cables in congested area
• Accurate multi-antenna design for various user selected locating modes directional peak, multi-directional null, plus a single antenna special peak mode for deep depths
• Directional mode utilizes all peak antenna design for improved left/right guidance and accurate locates in challenging conditions
• Compatibility with select GPS/GIS field mapping instruments for real time mapping of electronic markers or pipe and cable facilities
• The 3M™ Dynatel™ locator 2220M series is designed to find the path and estimated depth of buried pipes and cables
• Passive frequencies for power and cathodic protection system
• Detects frequencies from sondes and remote transmitters (512 Hz, 640 Hz, 33 kHz)
• Direct readout of active duct probe (zoned)
• Cable/pair identification
• Receivers incorporate an expander function to make peaks and nulls more pronounced
• Receiver and transmitter self test each time the unit is turned on
