10Hz GPS Based Performance Meter Box with Mobile App - Car Race Lap Timer and Drag Meter - Racing Accelerometer Data Logger

Really good piece of kit. It is extremely easy to use, always gets a good signal and the accuracy of the measurements seem very consistent. Good size display and suction cup holds well no matter how violently acceleration is. Highly recommend.

Is perfect for what we ordered it for. My husband loves it

I previously gave this a two star rating based on issues with the app which is important for future upgrades and capabilities for the unit. After providing details of my issue, the RaceBox team got back to me and asked me to verify a fix they made to address the issue in a beta release of the app. I got another unit and the app did connect to the unit. That weekend I had an opportunity to use the unit on track. It performed outstanding. The team added the track I was on a day after I requested it. The GPS was rock solid and accurate to within 8 inches. The output of the device while driving is very good and it gives great feedback for each lap to include letting you know you're running your best lap/segment for each session. The data captured by the device and ability to compare laps is very useful and accurate. The data files of your session can be uploaded to their cloud server and downloaded in file formats that are compatible with rendering software. I was easily able to sync my GoPro video with the data files. Only glitch was that the in car display showed speed in KPH not MPH. Figured that out when I was looking at 200 in the speed box on a back straight...I wish. The team indicated they are working on a fix for that but the data did properly record speed in MPH. I'm really looking forward to exploring some other capabilities of the unit next year. I can't say enough about the customer service from these folks. It was a 10. If your looking for something that can accurately record your session and lap times independent from various apps that run off your smart phone, then this is it. Would definitely recommend it.

Funciona increíble, sin hacer prácticamente nada pero no trae instrucciones por lo que hay que indagar por tu cuenta para encontrar los ajustes y opciones en el menú. Eso es complicado

Super Racebox! Einfache Handhabung! Kundenservice immer erreichbar bei Fragen Schnelle Rückmeldung! Die Box kann ich nur empfehlen!

There are so many things to like about the products but here are the main highlights for me. Great quality and very intuitive UI. I also like the fact that the app is constantly getting new features added. I love how easy it was to add a new race track (the device already has an impressive number of pre-loaded tracks but being able to add custom tracks fast and easy is a huge plus). I am impressed with the accuracy as I compared the results and they are very consistent. The display is very easy to read at a glance. I am not huge into drag times but I tested that function as well and I was impressed with the predictive function. Some of the other positives: -Compact and easy to store -Great Battery life -Easy to use -It takes no time to move it from one car to the next I can't wait for more track days so I can use it and improve my results.
