SPOT trackers are cheaper than I thought – I’d always thought the month charge was similar to a mobile, but it’s only a couple of quid.

PLB has no monthly charge (iniital cost is about £180) but they work anywhere with some view of the sky and th ebattery lasts about 5 years.

When my daughter was little we got some custom silicone wristbands made with our phone numbers on for her to wear when we were out and about at busy places in case she got lost / separated. I can’t remember the cost now, but they were pretty cheap.

I ride naked, I’m all for intrigue.
