The ARC T23 Series Two-Wire Surveillance Kit is very popular with nightclub, law enforcement, security, hotel staff, hospitality, and restaurant employees. The PTT wire is long enough to be run down the sleeve. The high impact polycarbonate microphone, PTT housing and the transducer is field repairable. The optional active noise canceling microphone cancels background noise during transmissions. The wires are Kevlar reinforced and include durable strain relief. The transducer can easily be switched out in the event of a future failure, saving the user money. The hypoallergenic acoustic tube is replaceable and is available in clear, black, or tan. The T23 also comes with an open ear insert for situational awareness.
