The Appareo Stratus ADS-B weather receiver is short on cost and long on value. When it’s connected to an iPad running ForeFlight Mobile Pro, the Stratus box brings free high-quality weather to the cockpit. Weather products include Nexrad, metars and TAFs, pireps, TFRs and more. Stratus, which has a built-in WAAS GPS in addition to its ADS-B receiver, is completely portable and operates without any wires. It has an eight-hour battery life and, best of all, it works flawlessly. Stratus sells for $799 and is available exclusively from Sporty’s Pilot Shop.
