DRT 4411B

Survey Equipment

Monitor a huge political protest

Review by Jennifer Lynch

Are you trying to monitor a huge political protest? Look no further than DRT. Nicknamed “dirt boxes,” these devices can locate up to 10,000 targets and can process multiple analog and digital wireless devices all at the same time. They’re even capable of intercepting and recording digital voice data. The best thing about the devices is the fact that no one may ever know you’ve used one. Just be careful — if your targets do figure out you’ve used a DRT box, and you haven’t gotten a warrant, they may be able to convince a judge to throw out all the evidence you’ve collected on them after you used the device.
