Peltor 3M Dual Com Tac III MT17H682FB-19 SVbrbr3M Peltor Comtac III two-way radio headset is the third generation of Comtac headsets to be produced by Peltor specifically for use in tactical and combat situations where durability in harsh conditions, compatibility with standard police and military gear, and reliable function are all basic requirements. The Comtac III ear cup profile has been improved, to better and more comfortably fit users wearing a variety of tactical helmets used by military and law enforcement professionals, including the Advanced Combat ACH and MICH Helmets. Ambidextrous boom mic placement, better salt water resistance, immunity to EMI events and improved TXTX fail safe features, all combine to make Comtac III the best two way radio headset available for the modern warefighter or tactical police operative. Comtac III has a fixed connecting wire with a NEXUS TP-120 plug that fits into the mating jack on your choice of PTT radio adapter cables. The PTT adapter cable then attaches to your portable radio or intercom system. A wide variety of PTT radio adapters are available to enable use of Comtac III with most two way radios currently in use.brbrIn addition to providing two-way radio connectivity, Comtac III includes two external microphones that pick up ambient sounds and amplify these up to 18 dB, providing the user with hearing that is considerably more acute while wearing Comtac III than he would have with an open ear. In the event of a nearby weapon discharge, the Comtac III amplifier instantly shuts down, providing the user with hearing protection from the noise event, automatically. As soon as the ambient noise returns to a safe level, the headset automatically resumes amplifying low sounds, providing unparalleled situational awareness while automatically providing reliable hearing protection every time it is called for.brbrFeaturesbrbr- Two-way radio connectivity with most radios via PTT adapter cables.
