@vinay: yes, you can compare runs and see the IMU lines. I'd recommend using the built-in comparison, which provides the delta time chart. This chart shows you in which turn/part/section you are going slow/fast. For example, you can pick a faster friend and overlay the two runs. You'll be able to spot where your friend is going faster.

@Life1: Well, it's missing some things... and it's even more expensive

@Janne88: at the moment with two, but it's possible to use more. Just an app update to add this...

@winko: You need a crystal (with its pF capacitors) to keep accurate timing, plus a good GPS module. Actually, 4 cores are not needed. You need a proper antenna, proper RF matching, robust code, robust hardware, and a lot of other things... Chrono is working very well in the woods, but for the best timing experience, you can always use the remote transponders. You can still compare routes and draw custom waypoints (based on GPS this time).

@rojo-1: Hello rojo-1, thanks for your questions. 1) The GPS is always present (since it's coming from the GPS), but you can decide to exploit the built-in speed sensor (thanks to a magnet placed on the wheel) to get the real distance traveled. This is very important to get accurate comparisons. 2) We're considering letting you load the Chrono files into our BYB Telemetry PC software. In this case, it will be possible to export the raw data. 3) Yes, the IMU data (3-axis gyro and 3-axis accelerometer) are included in the data set. You can consult the charts or see the shocks directly on the route (the route is changing colors according to the speed carried or the shocks perceived). We're always available to reply to your questions also here: [email protected]

Yeah, the main thing here is that you can pair with two remote triggers (transponders), one at the start and one at the finish. The trigger time is real and accurate. By the way, the GPS of Chrono is not comparable to a smartphone's or ciclo-computer's. It's very expensive, 25Hz refresh rate, and multi-constellation. You can clearly see that classic ciclo-computer GPS lines are usually "broken and very segmented". Chrono, even at high speed provides you smooth lines.

Hello everyone, I'm Enrico the founder of BYB Tech. When designing Chrono, we wanted to create an extremely accurate device. We are aware that the GPS reception can be poor inside a deep forest. To avoid that: 1) We tested more than 50 different antennas. We find out the best antenna considering a lot of different factors. 2) We're using a 25Hz fast refresh rate and multi-constellation module able to link to a lot of satellites. This module is extremely pricey and it's usually not used in commercial products. 3) We provide Chrono with a set of external remote triggers. The external triggers are essentially transponders. By using the triggers placed directly on the track your timing is not dependent on the the GPS reception. You'll get exactly the time you did between the start and finish trigger. More than having the proper time, you'll still get the GPS map and a lot of relevant information on how to improve your performance. Why do we implement the triggers combined with the GPS? Because, given two runs, is not enough to know if your run #1 is 03:45.347 and your run #2 is 03:46:281. It's more interesting to understand where you lost time in run #2 or what you did exceptionally well in run #1!
