SIR 30 - Hero
Flexible, modular design with advanced features
The SIR 30 is a customizable control unit that offers advanced filters and display capabilities for real-time processing including migration, surface positioning, signal floor tracking and adaptive background removal.
  • SIR 30 - Feature 1
    Versatile Unit

    The SIR 30 has numerous mounting configurations depending on how it is needed for each job and the work environment. This system has full internal GPS capability, USB and ethernet ports for full data transfer.

  • SIR 30 - Feature 2
    Deliver Results

    The SIR 30 was designed for high-speed GPR data collection- capable of more than 5,792 scans per second across four channels.

  • Rugged Design

    The SIR 30 is built with an aluminum exterior and rubber bumpers, and sized for vehicle rack mounts. For operation in harsh environments, GSSI created the SIR 30E, a modified version of our popular SIR 30. The SIR 30E can collect up to two channels of data.

Data Examples
SIR 30 - Data Example 1
SIR 30 2 Channel Data

Using a 2 GHz horn antenna, the top channel records asphalt layer thickness. The bottom channel shows sub-base layer information, including a shallow utility, that was collected with a 400 MHz antenna.

SIR 30 - Data Example 2
SIR 30 4 Channel Data

Data illustrates multiple utilities at varying depth. Data was collected as a 4 channel 400 MHz antenna array system with a custom made (user provided) cart configuration.

Antenna SupportCompatible with all GSSI analog antennas
Number of ChannelsRecords data from 1 to 4 hardware channels simultaneously; two 4 channel systems can be connected to form an 8 channel system
