Used in great working condition sentry ADSB with suction cup. Cable is not included.

Sentry is a compact, affordable ADS-B receiver specifically made for ForeFlight. In addition to popular features like ADS-B weather and traffic, Sentry also includes a carbon monoxide detector to warn of dangerous conditions in the cockpit. No larger than a deck of cards, Sentry packs long list of features into a small size, but still offers up to 12 hours of battery life.
