Well whatever DSC Handheld you use, I suggest you upgrade. It sounds more like a liability than a safety device. As Gotchi says, the Standard Horizon 851 does not suffer with any of those problems...
Even if a DSC radio were to send an old location, it would mark it as such and the speed and direction info would still be valuable to the rescuers.
