If you get Ross Bentley’s emails you probably already know that Garmin just released their new AI driving analyzer and coach, the Catalyst. Best that you read the marketing materials rather than me try to hit all the features but they are not (yet) competing directly with a full data system and advanced PC analysis software. This is a stand-alone tablet plus camera that records your laps then applies AI to identify “opportunities” to lower your lap times including real-time audio coaching for some things. If it were by some unknown company I would be thinking just another gimmicky gadget, but by multiple accounts Garmin has been working on this a long time. Anyway, it’s very focused, no additional inputs or add-ons but there’s still quite a lot to it. Even if all you want is a good predictive lap display and video with basic overlay, this isn’t a bad deal. At $1000 it’s the same as an AiM SmartyCam, JUST the camera.

Seems to offer similar functionality as the AIM Solo but a nicer display?  Is there some sort of software package for analysis like AIM offers?

It is not intended for PC based analysis and is both more and less than the Solo. It boils even the basic data down to the absolute basics, auto-comparing segments from your session of laps looking for what worked best then formulating specific recommendations for what to do with regard to speed, braking and line, what they term Opportunities. Then you can look at graphical representations of the recommendations and see both in graphs and synched images and video the difference between one lap and another, all compiled for you rather than trying to interpret the data yourself.

I think one of the best experiments would be to run it in parallel with a Solo then look at the AiM data to see if roughly the same conclusions are reached. Surely they did a lot of that during development of the AI.

One of the things unique to this, at least as I read it, is that the AI includes the video “view” as data input when evaluating your position on track etc. This is surely a first in consumer products of this type and if it’s legit then quite interesting.

Delivery of mine got pushed to end of the day but I’ll be posting what I learn with it on the Catalyst FB group over the next week.

There's not much technical info available that I could find, but the Catalyst sounds "interesting".  One inherent limitation with GPS data acquisition is that it can only be accurate to with a few feet.  That is plenty good enough for lap timing, calculating g-forces, etc, but for refining your driving line, it is not precise enough.  The Catalyst, near as I can tell from the marketing materials, seems to also use a high resolution video camera to determine your driving line with improved precision compared to GPS alone.  I suppose this is a spin off of all the work going on to use video to control self-driving cars, lane departure warning systems, etc.

autocrossers have been using 10hz gps to compare lines on an autocross course for 10 years. its accurate enough to compare line choice on a race track.

Well there’s accuracy in an absolute sense and there’s repeatability. This purports to be at the upper end of both for systems not using ground-based correction so under ideal conditions (the flat plains of Kansas) it may have sub-meter repeatability during the course of a session at least. :) But I think your surmise is probably correct.

First track test:

We had one in a car for the PDE at Gateway this afternoon but the driver managed only two interrupted sessions before someone in the intermediate group moved a wall with their Honda and ended the day. So total laps was about 17 of which only a few were at any pace. As the driver was also an instructor for other sessions he had little opportunity for me to demonstrate the capabilities so we didn’t get much review done. After session two I had accepted the coach voice prompts for the three identified “opportunities” to be active for the next session but that never happened. Oh well, we did at least get through the basic install & setup, recoded laps in two sessions and got “opportunity” feedback of several types for braking and line. The driver may choose to chime in here on his initial observations and experience though it was very limited.

Next up will be a very different test, twin 10 hour enduros this coming weekend. There really isn’t time to do this right so it might turn into an exercise in frustration, but there are so few opportunities left this season that we don’t want to pass one up. The most experienced driver is running first so the temptation is to let him put down a series of clean laps at the target pace then leave it running as a single session for all the others to work from. But of course that means no review during the race. So I’m sending a second unit to give them the option to swap it every driver change, allowing review of the most recent laps by the driver immediately after their session. First time out with it I favor the swap approach at least the first day, then decide which way to go on Sunday. I won’t be there myself but I’m hoping that their car is trouble free and circumstances allow them to work with the Catalyst.

This device looks pretty slick.  I'm curious as to how you mounted it.  I'm not a huge fan of the suction cup method.  Looks like there is a solid mounting method but still requires multiple arm "extensions" so mounting it flat somewhere does not seem to be an option.  Also the camera isn't moveable either with a single adhesive mount- not sure why they did that.  I'm sure there is a work around- thoughts on that one?

Because I’m moving it around a lot I’m using the suction cup. I agree that it is an iffy method particularly for something of any size and weight but done correctly the one they provide is very strong and I doubt it would come off short of fracturing the glass. A small screw/bolt down base comes with it and I would absolutely use that instead for a more permanent install but that won’t happen in a lot of track days cars.

My bigger issue with the mount system is that the tablet lacks any means of tethering it. It would have been a simple matter to incorporate a small tether slot in each end and should have been a no-brainer at the moment they chose a magnetic connection from tablet to base.

What did you do with the camera for mounting- assuming you are using it and didn't just use the adhesive?

The camera is not optional. I used the provided tiny adhesive mounts for now. There are small suction cup versions out there that probably use the same ball size but for now it’s simplest to just stick it on the windshield with the provided mounts. Easy enough to replace the adhesive and use them again, the camera is small and very light.
