This unit is like having a personal coach at your side. Its the first and only AED with a full-color interactive display that shows step-by-step videos for performing CPR, rescue breathing, and external defibrillation. It delivers clear text messages along with the corresponding videos that reinforce the voice instructions to coach rescuers how to properly use the AED and perform CPR. This unit is the smallest (weighs less than 3 lb) and the most durable, tested to U.S. military drop and shock specifications.
