In a market long saturated with portable ADS-B receivers, ForeFlight tosses a new model in the mix. Still, the $799 Sentry Plus could have enough smart features to attract the attention of buyers looking to replace aging vintage models, or even those who want to supplement new panel avionics.
At first blush, the 1.3-inch OLED display-equipped Sentry Plus seems large by modern standards, but there’s a lot packed into the 4.3 by 3.3 by 1.3 inch chassis. The device weighs 0.46 pounds and comes with a suction mount (attached via 1/4-inch-20 bolt tripod hardware) for window/surface mounting. In addition to external power input, power is also provided by an internal battery that has an 18-hour endurance, which ForeFlight says is the best in the market. What makes that battery life more impressive is the number of onboard sensors it has to power.
