Operators who switch shoulders, work around obstacles, or need to transmit without repositioning their grip can do so without adjusting technique. The ergonomic housing keeps both buttons accessible whether the unit is mounted on the left or right side of a chest rig or plate carrier.\u003c\/p\u003e\n\n\u003ch2\u003eNEXUS Connectivity Across US and NATO Headsets\u003c\/h2\u003e\n\u003cp\u003eNEXUS headset connectivity means the PT21 works with a wide range of tactical headsets built to US and NATO standards, not only Silynx's own lineup. Operators who already run a compatible headset can integrate the PT21 without replacing existing equipment.
