Garmin Catalyst‪™‬ 4+

I bought this device right when it came out and I’ve been using it for the last couple years. It’s truly an unbelievable device. I have Motec in my race car and it’s quite complex. This device is the very simple to use and allows me to have realtime input while I’m racing. I connect the audio to my headset, so lap by lap, I get info about how to drive each corner better. This is invaluable during qualifying and racing. Five stars.

I’ve now done a complete season using the Catalyst. As a lap timer it has been excellent, I like seeing real time if I’m ahead or behind my session best, def helps you concentrate on getting better. The coaching part I have not really used as I cannot here the voice over the wind and engine noise! But you can use ear buds, but I just haven’t.
I do like the optimal lap view, this is what I use to improve my laps the most. Piece it together and eventually you can achieve that ‘optimal’ lap. I’ve only managed that once at my last track day. My best lap was within 0.01 of the ‘optimal’ lap. I was very happy!
I took 1 star away as I feel the video recording is just average. It says it’s 1080P but my GoPro 1080P looks 10x better. Maybe 720P at best, being able to overlay the speed/map/ G’s data is awesome, that part I love!
Overall a great product, highly recommended, even if the video quality could be better. The rest is outstanding!!!

Driving against your own self is probably one of the hardest things to do. The Garman has made it not only a challenge, but also a blueprint on how to do better, driving thank you for coming up with such a great tool to use for a weekend driver like me. I hope that you can make it even more simple somehow but it’s pretty good.
