PACKTALK PRO comes with a built-in crash detection sensor made especially for on-road motorcycle riders. It senses what your head feels and knows exactly when to make that important emergency notice when things go wrong. But it doesn’t stop there. With our top-of-the-line 45mm JBL speakers as standard, expect nothing but the best sound in the business. Our newest PACKTALK PRO is not just about brains. With an all-black-matte exterior it is a marvel of stealth and beauty. Auto On/Off, 15 DMC group members and IP67 design are there to augment your active lifestyle. PACKTALK PRO - mind-blowing performance now comes standard.
