VERT Wearable Jump Monitor with Jump Rate is a device worn near the waist of an athlete either by the VERTclip (for combines and quick testing) or integrated within an article of clothing such as the VERTbelt (for practice and games).

anyone used one? how accurate? wud be interesting to see the results compared against a known reliable method (Vertec) ..

i wouldnt mind hacking up something similar if it's reliable with older phones lying around

adarqui:
i was actually looking for this specifically (*i think*) .. saw it on some show on espn.

nice thanks!

I plan to eventually get something like this and play with it.. surprised none of us dabble in these vert devices (yet).

Coges:
That's surprisingly reasonably priced if it's quality and gives accurate measurements.

To be honest i dont know if they have any special sauce which you can't get with any device with an accelerometer. eg go on aliexpress and you can pick up a chip with bluetooth 4.0, accelerometer etc for $1/each. There's also more 'established' alternatives with sensor devices like the Metawear R for around $38 usd. Im tempted to get a few units off aliexpress and play with them. The vert linked above seems to be IOS only .. and it seems way overpriced to me for what it does.

I really do like the idea of exploring putting an accelerometer on your COM to get true vertical instead of stretchy/tippy toey/ vertical but i do have some doubts. for one how do you find ones COM accurately? does it even matter? And finally .. how does it compare to say video. Did anyone work out a good way to get accurate vertical off video? using COM i guess

Exactly, there's error associated with every method. Counting frames on video is also inaccurate (there used to be a good post by vag about the hangtime calculator for example but I can't find it). I've said it 1000X, the best and cheapest way is [highest touch-standing reach or head height]. You can measure your reach or height very accurately and indoor basketball rings are pretty standard (and you can measure them as well if there's doubt). Then just frame the jump video well enough and you're going to be very accurate. If you have money to burn go for it but I'd spend the money on better shoes, protein, bands....
