Garmin describes the GDL 88 as the “first dual-link solution for certified aircraft that not only provides a path to ADS-B Out compliance for many pilots, but also brings subscription-free weather and advanced traffic display to the cockpit.”
While we’re more than a little tired of hearing marketing types trumpet everything from a cup of coffee to software version umpty-dot-twelve as a “solution,” we found that the GDL 88 is currently the easiest way to get a full-up, self-contained ADS-B-compliant system.
