I suspect they could get several cellular GPS devices for the cost of an iPhone + some AirTags - meaning they could easily offer up one or two sacrificial ones for easy finding in order to hide a smaller one "in plain sight" (as it were.)

Or someone even less scrupulous for even less money, I'd assume?
