MASW Tool Package Lease

Contact for quotes.

We provide a complete set of tools (hardware and software) for MASW investigation with short- (1 day) and long- (multiple month) term
leases.  Each package comes with a laminated (5-page) binder for data acquisition and processing instructions.  How to assemble
hardware components and how to set data-recording software are graphically illustrated in the binder.  Each package comes with the
ParkSEIS (v. 3.0) AUTO data-analysis software, which can be used in the field to automatically generate the desired result (1D profile or
2D cross section) after data acquisition.  AUTO results are reliable for most MASW data sets (~75%) that have high-very high signal-to-
noise (SN) ratios.  Brief instructions on how to process more challenging data sets (low-medium SN ratios) are also graphically
illustrated by following the conventional (manual) data-analysis sequences.  

We provide rental packages with preset configurations for both 1D and 2D surveys in the following depth ranges:

  • shallow (< 30 ft)
  • medium (< 50 ft)
  • deep (< 100 ft)
  • very deep (< 300 ft)

All packages will include the following (basic and optional) items needed for MASW surveys:
