Is there any way for me to buy it locally in the US or is it only available in France?

Thanks.

Only available in France. Easy to deal with them directly, no issues.

Iíd seen this on eBay while back. Iíve got a timing system for single vehicle. But the ability to do multiple vehicles has me interested now.

Do any other transponders work with this system?

No, only their transponders.

If you notice any miss lap, you can easily change LapMonitor location on the track to keep on getting good detection as LapMonitor has a long bluetooth range
How much in U.S. dollars, would it cost for the timing system, each additional transponder, and shipping to the U.S. ?

Thanks for the post. I have a nice backyard track and use a phone app that will record and broadcast via bluetooth one car at a time on track. My racing has improved dramatically since finding that app, to the point I also now keep excel spreadsheets to track my laps, fast laps, average laps, efficiency, and standard deviation of all my practice time. I've been looking for an affordable way to add competition (more cars) to the practices, and this looks like it may be it. I'll be checking this out for sure

Iíve been doing similar for on road and MiniZ. Iíve got a individual system(Zeppin lap timer) and use LapTracker app for my phone. But Iím starting to consider this for the 1/18 group I run with.

Today there was a post on lapmonitor's facebook regarding differences of 1/100 sec which reminded me that when I tested it, for the local track, this effect was way bigger (tested by checking at the two extremes of the track's width when the car was detected).




Anyone knows if this is somehow handled by the software or hardware? I don't care, at all, it's a fantastic product, I'd just like to be able to now what is a significant difference and what is car placement between laps, and of course over multiple laps this will average out.

Hi, thanks for explaining this case, indeed when car path when passing the lap counter is very different between two passes (your drawing is showing the worst case) then accuracy is worse than few 1/100s .
But this is not the normal use case of racer who is battling for a 1/100s .The error in this case is dependent of the speed, the faster the car goes the better is the accuracy, for example a car at passing the lap counter at 40km/h and a lap with 2 passes separated by 2 meters you can get an expected error of 6/100s
Also this error is not cumulative and will be canceled at next lap when going back on the common car path of the driver.
We tested on a track and compared to video timestamp and error was few 1/100 secs differences (usually less than 2-3/100s) you can check it on some of our youtube video
This can be improved with software but not yet implemented in our software but as I wrote above the case you describe is not the normal use case when you're doing your best laps and as you wrote and expect the next lap this error is automatically corrected

I've been using Lap Monitor for a few months now. The Lap Monitor is within 1 to 3/100 secs of My Laps. A lot of my buddies use Lap Monitor and all have had great experiences out of it. It's a great tool to have at the track.
