N2  - A new Scintrex gravimeter, CG5, was released onto the market in 2002. The CG5/352, which was upgraded from the CG3M/352, was tested at various fields. CG5 meter has a new raw data acquisition mode. If the mode is enabled, unprocessed 6 Hz data (gravity, tilt-x, tilt-y, and temperature) are stored in memory. I examined the potentialities of the raw data recordings to improve efficiency of gravity monitoring. Long-term changes which evolve over months and years can be monitored by gravity measurements with profile or areal coverage at respective repetition intervals. If short-term changes are expected, high repletion rates and/or continuous gravity recordings will be required. Postprocessing the raw data is effective to detect signals both in the cases. A combination of the continuous measurements and reiteration surveys with CG5 meter can cover a considerable part of the ranges both in time and space domains.
