Mini S - Standalone GPS Based Performance Meter Box 25Hz - Car and Motorcycle Lap Timer and Drag Meter with Mobile App - Vehicle Racing Timing System

Typically, to have something like this costs thousands of $$$ but somehow Racebox managed to squeeze an incredible amount of tech into a small, very affordable device that's about the size of a JBL clip speaker (3x3x1 inches roughly). It has extremely accurate GPS (down to about a foot) and an accelerometer that updates much more than the usual once per second that pretty much any phone or camera like a gopro or insta360 captures, which means clean telemetry data for all your track day videos that nobody watches but your mom. It has a good battery which should last a whole day at the track and hours worth of space for recording. The app works very well and is fairly easy to use. It has hundreds if not thousands of tracks and layouts pre-programmed in the unit and it somehow also records weather conditions and timestamps on all your recordings. I could write a review 10x as long on all of its features but just do yourself a favor and buy one already. Lastly, for motorcycles they recommend placement on the tail but this was where I mount my insta360 sometimes, I instead placed it on the fuel tank under my chest when tucked. I thought this might impede the gps reception but it had zero effect. The device was getting down to 1 meter accuracy inside my house! So if you're outside, expect it to be around 10-12 inches regardless of placement. (For comparison, most phones barely get within 15ft, but can at times be hundreds of feet inaccurate).

I’ve met some track folks and this is the one you want I’ve realized . Gps built in, no phone needed to be with you . Simple and easy

One best lap timer of all time.

Buon GPS

Fitted under the seat of my panigale and works great
