The Glottal Enterprises EG2-PCX2 Electroglottograph uses a patented 2-channel configuration with dual electrodes that provides an electrode positioning indicator on the front of the unit. This allows for locating, verifying, and recording proper electrode position, which is an advantage over single-channel EGGs. The roughly parallel electrode surfaces in the EG2-PCX2 provide a quasi-uniform electric field through the neck that produces a signal less sensitive to electrode position changes compared to other EGGs with circular concentric electrode surfaces. The EG2-PCX2 offers several additional features over the KayPentax EGG such as USB connectivity, dual batteries, signal strength indicator, microphone
