Portable ADS-B receivers just keep getting better, and ForeFlight’s Sentry series is a good example of this trend. Since the FAA created the 978 MHz automatic dependent surveillance-broadcast (ADS-B) network and added ADS-B In to incentivize pilots to equip with ADS-B Out transponders, the capabilities of portable ADS-B In receivers have multiplied.

The latest Sentry Plus doesn’t change the basics of ADS-B In, but it adds features that make it a more useful device including battery life of more than 18 hours, a high-performance flight data recorder, g-meter, and automatic power on/off setting. The new features accompany a 1.3-inch OLED display on the Sentry Plus, which shows battery level, carbon monoxide (CO) status, acceleration (g-load), groundspeed, and GPS accuracy. The display also gives information on connectivity with smart devices, track log download progress, and firmware update status.
