Think of it as body armor for your measurement microphone(s), or any other prized possession of similar size that you need to protect from harm and the elements. Our MICro Case accommodates one or two of most of the mic's we sell, but is compact enough to fit in your backpack, shoulder bag or briefcase without evicting the rest of your gear. Constructed of ABS plastic for high impact strength, even at low temperatures, this case is shock-resistant, crush-resistant, air tight, dust-proof and actually submersible to 100 feet. It even floats — a definite nice-to-have if you work near water or routinely swim to your jobs.
