Garmin Catalyst is an industry-first racing coach and driving performance optimizer (device not intended for public roadway use) that’s changing the world of motorsports. It mounts in the cockpit, gathering performance data and providing real-time audible coaching. Immediate session analysis helps drivers of all levels achieve their full track driving potential. Groundbreaking True Track Positioning technology uses built-in sensors and 10 Hz multi-GNSS positioning to automatically generate your car’s racing line on the track. Plus, our revolutionary True Optimal Lap technology shows your best achievable time, based on lines you actually drove and can repeat. While on the track, hear real-time coaching cues through a compatible Bluetooth-enabled headset or car stereo (headset sold separately). After your session, use the touchscreen display to immediately review your performance data and see your major areas for improvement.
