ForeFlight thinks there’s still a sizable market for budget-based portable ADS-B receivers so it came to AirVenture last month with a new model: the Sentry Mini. Think of the Mini-priced at $299-as the little brother of the full-sized Sentry receiver ($499) the company brought to AirVenture last year.
Like the full-sized Sentry, the new Mini is made by Montana-based uAvionix and has dual built-in antennas for receiving weather and traffic on both 978 MHz and 1090 MHz frequencies. The product’s name suits it well-the device is 3.3 by 2.3 by 0.6 inches and weighs 0.1 pounds. Check that against the full-size Sentry, which measures 3.25 by 2.25 by 1.25-still compact.
