ForeFlight has introduced the latest update to its Sentry series of portable ADS-B units, the Sentry Plus, joining the original Sentry and Sentry Mini for use on a wide range of aircraft when linked to an iPad.
The lightweight plastic-case Sentry Plus builds on previous models, allowing for subscription-free ADS-B traffic and weather information, and adding a list of features to include carbon monoxide (CO) monitoring and track logging.
