The tracker detect app makes the blue tooth trackers useless or worse a target if it is in a shed.
Also the range is limited. The TKSTAR is just a mobile phone with a specific use. I know mobile phones can be detected but hopefully you cannot distinguish between a phone and a tracker.
I still put my faith in a large chain and larger lock. Not perfect but I hope it would deter the buggers. Hidden trackers do not deter.
Datatag is a good idea. I use it on my household goods but never thought about on the bike. It wouldn’t stop it being stolen but it might lead to its return.
