The DAS-M is the latest system from MPT, it is modular, flexible, and supports multi-source transmitting.

Multiple main units can be chained together with or without multiplexors to add more electrodes, receiver channels, and transmitters to the system.

Flexible data acquisition modes including spectral IP and full waveform recording at 1200 samples/second.

Radio Communication

The DAS-M uses radio communication to operate the system from a normal Windows PC or Tablet. 

Averaged data can be sent real-time to the control PC while full waveform data is recorded to a USB flash drive attached directly to the system. 

Patented Multi-Source Transmitting

Each main unit has a built in 250 watt transmitter and 4 high precision, fully independent receiver channels. 

It is possible to transmit from each DAS-M simultaneously, even from completely separate lines of electrodes. 

Transmitting from multiple units at once allows for greater depth without large, high power, transmitters. Transmitting and receiving between separate lines allows for extreme flexibility when working in rough terrain and urban settings where it may not be possible to run cables for traditional ERT systems.


The DAS-M was designed from the start with modularity and expandability in mind while reducing the need for extension cables.


Adding a MUX-M box expands the system by up to 16 electrodes without the need for extension or dedicated signal cables. 

A second DAS-M can act in exactly the same manner as a MUX-M, but it can also allow for use of it's internal transmitter and receiver channels for unparalleled flexibility in the field.


This system was designed from the ground up to be ideal for surveys in urban settings and difficult terrain. 

Each box is light weight and easy to carry, with minimal connections required in each setup. 

Multi-Source transmitting makes previously impossible site configurations accessible, even transmitting across roads, rivers, or other impassible areas. 

The main units also support full waveform recording at 1200 samples/second on all 4 channels.

Fully independent receiver channels allow for greater flexibility in array design.
