>>761510VHF/UHF has a bit of a limited range (less than 150km in best circumstances,) and their effectiveness depends a lot on where you are and who's listening. In some cases, they're quite useful if you can hop on a forrestry/park repeater and ask for help, or raise somebody through the local HAM or GMRS repeaters. In other cases there won't be anyone on frequency and you'll just be stuck until somebody calls it in after you don't get back in time and then you can use the radio to guide in search teams, IF you have their frequencies.
If you're looking for something to reach out for help when you're in remote areas then you should consider a SPOT or PLB. If you want to chat with your friends while out hiking in separate groups then get one of these and stick to MURS frequencies.
