Sandwich Box Mark III

The new Mark III version of our Sandwich Box independent vibrator test system is now on sale. As every product of ours is vigorously tested this will ensure our product meets the requirements of the users.


The new Mark III version of the Sandwich Box benefits from:

  • Differential inputs
  • Externally triggered by TTL
  • Easier more flexible software
  • 32 bit seismic quality A/D converters
  • Extended low frequency response


Hardware and software are similar to that of the Mark II version to minimize the requirement for retraining.
