Fly with confidence and peace of mind. Fly with Mid-Continent Instruments' new 4300 series electric attitude indicator — the Lifesaver^® gyro. Even if every other system in your aircraft's avionics panel goes dark, the Lifesaver^® powers on. The only attitude indicator with a self-contained battery backup, it delivers one full hour of emergency attitude reference. One hour of precious time to pull you through when trouble strikes and all other power fails. Can you live without it?
