The Vibroplex© Iambic is the modern descendent of the Original. It incorporates the traditional Vibroplex© look for use with modern electronic keyers. The code speed with the Iambic depends on the particular electronic keyer with which it is operated. And, you get the same crisp operation at 5 words per minute as you do at 50+ wpm. Weight 5 lbs. Cord not included. Available in four models.
