The new SwatTAC II is built to military specifications. The electronic headset features a new thinner profile designed for an ideal fit under PASGT model ballistic helmets. A new volume/on/off control pad design is easier to use and waterproof. The advanced electronics operate on 2AA batteries (good for 270 hours) and enable 2-way radio communication at all times even if the batteries deplete during use. The headset, built by Peltor, comes standard in covert black with blackened steel arm guides to eliminate any possibility of glare or reflection. The flexi-boom microphone is noise canceling and there are a wide assortment of military and police radio in-line PTT options available. The cups offer a noise reduction rating (NRR) of 21 dB and the electronics offer omni-directional, ambient surround listening ability in stereo with a safety impulse cut-off of 82dB.
