Separation Alert device

[Angeli]

Hi guys

I have a tendency to leave my cell on a table in clubs

As I have a new cell, I would like to take some device, one part in my pocket, other attached to the cell, and when the distance between two is at some point (1m, 2m) it emits a sound

After some searching I found TrackR 2 generation, then trackR Pixel, etc - what are your experiences and what would you suggest?

I need a loud tone, and working
...distance testing is really not an issue, as I guess all will work on those 2m I need

tnx
