Personal mobile radio: It's a standard that operates on the 446 MHz band. It has eight channels with a couple of 'tone squelch' systems ('privacy channels'), with CTCSS being perhaps the most common. Range is typically about a kilometer, which is adequate for convoy use where the vehicles are rarely more than a couple of hundred metres apart. Here's a Wikipedia link. You can buy a pair of handheld transceivers for under £50, which would probably work OK, but you tend to get what you pay for. HTH, GeoffSorry what’s PMR !!!!!!

Edited to add that you don't need a licence to use PMR.
Check what licence You'll require to work Amateur radio outside the UK because the entry level licence isn't accepted anywhere else. Other than VHF with limited distance amateur radio isn't a guaranteed method for emergency communication I'd be think along the lines of a satellite phone if going seriously off gridHi all, we are looking at overland, remote areas of the world ( possibly fort william?) no seriously areas like India, South Africa,
