Does anyone have any experience using either GMRS or MURS handheld radios in the backcountry for emergencies? If so what are the benefits and what exactly can you do with them. Specifically can you use both to talk to your bush pilot....when in range. I'll be using it in Alaksa so is one better than the other to contact troopers/uscg for emergencies? main use will be in the interior, not along the coast when chatting with the CG would be easy.
