Find your line to faster times with the Garmin Catalyst 2 racetrack driving performance optimizer. This compact all-in-one device mounts inside your cockpit and features a bright 3" touchscreen display and HD camera. On the track, real-time audio coaching (available in select languages) adapts to your performance — interpreting data and providing audible guidance while prioritizing opportunities for improvement. After the session, open the Garmin Catalyst app on your tablet or smartphone to see a composite video of your optimal achievable time with patented True Optimal Lap technology. Review your detailed performance data from the road course or drag strip — or compare your stats with friends’ data and get exportable 1440p HD videos with data overlays (requires internet connection). With purchase of a Vault plan, you can also view videos from friends and leaderboards.
