Maximize your performance on the racetrack with the Garmin Catalyst track recorder and race coach. You'll make the most of your day of recreational track driving with analysis of your performance, audible coaching from the Catalyst over your car stereo or headset, and maps showing exactly which line will get you through the turns the fastest. The Catalyst uses multiple global navigation satellite systems and a global track database to precisely plot your location on the track, and its True Optimal lap feature combines your best times for each track segment to show your optimum drivable time, using lines you drove and can repeat. Best lap time, delta (pit stop) times, number of laps, and total session time are captured for review, and the Catalyst's Automatic Interpretation technology saves you from having to upload data to a computer for thorough analysis. It's easy to compare track sessions and get immediate adaptive suggestions on improving your performance. The included dash cam records your session and can be played back synced with your driving data. The unit comes with a mount for your car that can be effortlessly adjusted for easy viewing.
