The Radio Shack meters are fine for measuring instantaneous levels near the source. Good inexpensive device for testing models for compliance with club standards, once such standards have been established. For measurements needed to set club standards traceable to the applicable codes and ordinances in the locality, an integrating/recoding meter is needed, for a couple of reasons. Ordinances usually specify allowed maximum levels at the noise sensitive sites (residence, school, et al) usually at the property line, at an 'equivalent' dB level, that is an average over some specified time period, usually one hour. The RS meter doesn't have the sensitivity (lowest range is 60 dB) to monitor typical ambient levels and noise abatement ordinance-specified levels at the impacted (i.e., receiving) locations, nor the ability to record a running average of measured levels over some interval. A sound meter up to that task is too expensive to warrant purchase by a club, but can be rented for the short time (a day or two) needed to conduct a reasonable sound survey. The whole point of the survey is to be able to demonstrate, in exactly the same measurement units and at the same locations as specified in community standards, that those standards are being met when your club standards for source levels are being adhered to.
