Appareo has raised the bar again. The Stratus 4 is the most powerful portable ADS-B receiver the company has ever built, packing a full-color touchscreen, integrated G-force meter, flight data recorder, and an 8-hour swappable battery into a unit that weighs just 10.6 ounces. If you rely on subscription-free weather and traffic in the cockpit, this is a significant upgrade.
