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. Iambic Standard - A neat, crisp black textured finish base with bright decorative chrome top parts. Non-jeweled movement.
